The pressure of a 70.0L sample of gas is 600 mm Hg at 20.0C. If the temperature drops to 15.0C and the volume expands to 90.0L, what will the pressure of the gas be?

Answers

Answer:

458.7 mmHg

Explanation:

Step 1:

Data obtained from the question. This includes:

Initial volume (V1) = 70L

Initial pressure (P1) = 600 mmHg

Initial temperature (T1) = 20°C

Final temperature (T2) = 15°C

Final volume (V2) = 90L

Final pressure (P2) =...?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This is illustrated below:

T(K) = T (°C) + 273

Initial temperature (T1) = 20°C

Initial temperature (T1) = 20°C + 273 = 293K

Final temperature (T2) = 15°C

Final temperature (T2) = 15°C + 273 = 288K

Step 3:

Determination of the new pressure of the gas.

The new pressure of the gas can be obtained by using the general gas equation as shown below:

P1V1/T1 = P2V2/T2

600 x 70/293 = P2 x 90/288

Cross multiply to express in linear form

P2 x 90 x 293 = 600 x 70 x 288

Divide both side by 90 x 293

P2 = (600 x 70 x 288) / (90 x 293)

P2 = 458.7 mmHg

Therefore, the new pressure of the gas is 458.7 mmHg

What is the molariity of a 50.0 mL aqueous solution containing 10.0 grams of copper (II) sulfate, CuSO4?

Answers

Answer:

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]

Explanation:

Molarity is a unit of concentration that is based on the volume of a solution and represents the number of moles of solutes contained in a liter. The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution and is expressed in units (moles / liter).

[tex]Molarity=\frac{number of moles of solute}{Volume}[/tex]

You must calculate the number of moles of CuSO₄. So, being:

Cu: 63.54 g/moleS: 32 g/moleO: 16 g/mole

the molar mass of CuSO₄ is

CuSO₄=63.54 g/mole + 32 g/mole + 4* 16 g/mole= 159.54 g/mole

Then it is possible to apply the following rule of three: if 159.54 g of CuSO₄ are present in 1 mole, 10 g in how many moles are they?

[tex]moles=\frac{10 g*1 mole}{159.54 g}[/tex]

moles= 0.063 moles

Then:

number of moles of solute= 0.063 molesVolume= 50 mL= 0.05 L (Being 1L=1000 mL)

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.063 moles}{0.05 L}[/tex]

Molarity= 1.26 [tex]\frac{ moles}{L}[/tex]

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]

Which hydrocarbon belongs to the Alkyne homologous series?
(A) CHCH
(B) CH2CH2
(C) CH3CH3
(D) CH3CH2CH2CH3

Answers

Answer:

(A) CHCH

Explanation:

Hello,

Alkynes are formed when triple bonds are formed between carbons, it means that due to the triple bonds, three bonds are already exhausted and carbon atoms need four bonds to attain the octet, for that reason, an extra bond is allowed. Now, such extra bond, when talking about hydrocarbons is filled with hydrogens, for that reason the alkyne should be (A) CHCH as it also accomplishes the following formula which is not accomplished by the rest of the options:

[tex]C_nH_{2n-2}[/tex]

Since n=2, we have:

[tex]C_2H_2[/tex]

Which matches with CHCH.

C2H6O(g) + 3O2(g) 2CO2(g) + 3H2O(g) Inside the piston of an automobile engine, 0.461 g of ethanol (C2H6O) gas reacts with 0.640 grams of oxygen gas to produce carbon dioxide and water, according to the balanced equation shown above. What is the limiting reagent?

Answers

Answer:

Oxygen is the limiting reactant.

Explanation:

Hello,

In this case, given the reaction:

[tex]C_2H_6O(g) + 3O_2(g)\rightarrow 2CO_2(g) + 3H_2O(g)[/tex]

Hence, given the masses of both ethanol and oxygen, we are able to compute the available moles ethanol by:

[tex]n_{C_2H_6O}^{available}=0.461g*\frac{1mol}{46g}=0.01mol C_2H_6O[/tex]

Next, we compute the moles of ethanol that react with the 0.640 grams of oxygen considering their 1:3 molar ratio in the chemical reaction:

[tex]n_{C_2H_6O}^{consumed\ by\ O_2}=0.64gO_2*\frac{1molO_2}{32gO_2}*\frac{1molC_2H_6O}{3molO_2} =0.0067molC_2H_6O[/tex]

In such a way, since there are 0.01 available moles of ethanol but just 0.0067 moles are reacting, we evidence ethanol is in excess, therefore the oxygen is the limiting reactant.

Best regards.

Answer:

Oxygen O₂ will be the limiting reagent.

Explanation:

C₂H₆O(g) + 3 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(g)

First of all you must know by stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) how much mass of each compound reacts. First of all, being:

C: 12 g/moleH: 1 g/moleO: 16 g/mole

the molar mass of each reagent is:

C₂H₆O: 2*12 g/mole + 6* 1 g/mole + 16 g/mole= 46 g/moleO₂: 2*16 g/mole= 32 g/mole

Then, since 1 mol of C₂H₆O and 3 moles of O₂ react by stoichiometry, the amount of mass that reacts is:

C₂H₆O: 1 mole* 46 g/mole= 46 gO₂: 3* 32 g/mole= 96 g

Now you apply a rule of three as follows: if 46 g of C₂H₆O reacts with 96 g of O₂ by stoichiometry, 0.461 g of C₂H₆O with how much mass of O₂ will they react?

[tex]mass of O_{2} =\frac{0.461 grams of C_{2}H_{6} O*96 grams ofO_{2} }{46 grams of C_{2}H_{6} O}[/tex]

mass of O₂= 0.962 grams

But 0.962 grams of O₂ are not available, 0.640 grams are available. Since you have less mass than you need to react with 0.461 g of C₂H₆O, oxygen O₂ will be the limiting reagent.

Which statement is true about the total mass of the reactants during a chemical change?

Answers

Answer:

Explanation:

just took the test

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, the correct option is option C.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope. In chemistry relative mass is equal to the mass of one-twelfth the mass of C-12 isotope .

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

The total mass of the reactants during a chemical change is equal to the total mass of the product.

Therefore, the correct option is option C.

Explanation:

water is a highly polar molecule with strong hydrogen bonding. one of the results of this is that water can climb up a narrow tube. the phenomenom is known as:
A. catapult action (aka trebuchet onfire)
B. capillary action
C. carpel tunnel syndrom
D. capitalization

Answers

Answer:

Option B, Capillary action

Explanation:

Water molecules attach with the molecules of the surface of the container in which they are kept. This is because of the cohesive force within the molecules of water and adhesive force between the molecules of water and other substances.

The water rises up in a capillary tube because of water molecules adhere at the edges thereby creating a meniscus in the upside turned direction. The surface is kept intact by the surface tension

Now capillary action specifically occurs when adhesion to the surface of the container is higher than the cohesion between the water molecules.  

Hence, option B is correct

What is the molarity of a 50.0 ml aqueous solution containing 10.0 grams of table sal, Nacl?

Answers

Answer:

The molarity of a 50.0 ml aqueous solution containing 10.0 grams of table sal, Nacl, is 3.42 [tex]\frac{moles}{L}[/tex]

Explanation:

Molarity is a unit of concentration based on the volume of a solution and is defined as the number of moles of solute per liter of solution. Then, the molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution.

[tex]Molarity (M)=\frac{number of moles of the solute}{volume of the solution}[/tex]

Molarity is expressed in units ([tex]\frac{moles}{liter}[/tex]).

Then you must know the amount of moles of the NaCl solute. For that it is necessary to know the molar mass. Being:

Na: 23 g/moleCl: 35.45 g/mole

the molar mass of NaCl is:  23 g/mole + 35.45 g/mole= 58.45 g/mole

Then a rule of three applies as follows: if 58.45 grams are present in 1 mole of NaCl, 10 grams in how many moles will they be?

[tex]moles=\frac{10 grams*1 mole}{58.45 grams}[/tex]

moles= 0.171

So you know:

number of moles of solute= 0.171 molesvolume= 50 mL= 0.05 L

Replacing in the definition of molarity:

[tex]Molarity (M)=\frac{0.171 moles}{0.05 L}[/tex]

Solving:

Molarity= 3.42 [tex]\frac{moles}{L}[/tex]

The molarity of a 50.0 ml aqueous solution containing 10.0 grams of table sal, Nacl, is 3.42 [tex]\frac{moles}{L}[/tex]

Which of the following human activities can increase the risks of flooding?

deforestation i hope this helps

Answer:

Deforestation and Cultivation

Explanation:

First I am going to give the definition of deforestation:

Deforestation is basically the removal of trees.

The removal of trees leaves leaves very little vegetative cover to hold heavy rain fall. This is why mudslides and things happen. When the land is clear and flat, the water keeps on going instead of going into the soil. That water that keeps on going is called runoff water. If we planted trees by the rivers, that could take down the height of the floods in towns by 20%

At first I was going to say widening rivers, but that is a way to manage river water. When we lengthen the river, it is so that the water can take more time to reach the river canal.

Definition of Cultivation: The production of food by preparing the land to grow crops (especially on a large scale) animal husbandry - breeding and caring for farm animals. agriculture, tree farming - the cultivation of tree for the production of timber.

I was also going to say Cultivation. Over-cultivation is the excessive use of farmland to the point where productivity falls due to soil exhaustion or land degradation. Now this is actually why we have floods in the USA. The soil cannot soak up any water, therefore the water over flows and that is when a flood starts to happen.

Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. Cylinder B contains a gas that has a temperature closest to absolute zero.

Answers

Answer:

The correct option is;

Cylinder A contains a gas that has a temperature closest to absolute zero

Explanation:

From the kinetic theory of gases, the average speed of a gaseous molecule is found from the following equation;

[tex]v_{rms} = \sqrt{\frac{3\cdot R \cdot T}{MW} }[/tex]

Where:

[tex]v_{rms}[/tex] = rms speed which is the square root of the average of the velocities of the gas molecules squared which is used in place of the average of the gas molecules as the sum of the velocities of all the gas molecules in the cylinder is zero

R = Universal gas constant = 8.3145 J/(mol·K)

MW = Molecular weight of the gas

Hence where we have;

[tex]v_{rmsA}[/tex] = Average velocity of gas A = 0.0000001 m/s

[tex]v_{rmsB}[/tex] = Average velocity of gas B = 0.3 m/s

Since, R and MW are constant for the gas in cylinder A constant, therefore, as [tex]v_{rmsA}[/tex] ≈ 0 m/s, the temperature, [tex]T_A[/tex], of gas A is closest to absolute zero.

Answers

Answer: [tex]CO[/tex] is the limiting reagent and [tex]Fe_2O_3[/tex] is the excess reagent.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Fe_2O_3=\frac{42.7g}{159.69g/mol}=0.267moles[/tex]

[tex]\text{Moles of} CO=\frac{13.2g}{28g/mol}=0.471moles[/tex]

The given balanced equation is :

[tex]Fe_2O_3(s)+3CO(g)\rightarrow 2Fe(s)+3CO_2(g)[/tex]

According to stoichiometry :

3 moles of [tex]CO[/tex] require = 1 mole of [tex]Fe_2O_3[/tex]

Thus 0.471 moles of [tex]CO[/tex] will require=[tex]\frac{1}{3}\times 0.471=0.157moles[/tex]  of [tex]Fe_2O_3[/tex]

As given amount of [tex]Fe_2O_3[/tex] is more than the required amount , it is the excess reagent.Thus [tex]CO[/tex] is the limiting reagent as it limits the formation of product.

How many grams of KF are in 2 liters of a 3.0 M solution of KF

Answers

Answer:

mass ( g ) = 348 g

Explanation:

First you know : M = mole / volume (L)

in question you have the M and V and the formula of SUBSTANCE ( KF )

first you get the number of mole from equation above

so 3 = no of mole / 2

no of mole = 3 × 2 = 6 moles

and the moles equation is no of moles = mass ( g ) / molecular weight ( g/mole )

so you have already calculate the moles and you can know the MW from the Question

Mw of KF = 39 + 19 = 58

so n = mass / MW

so 6 = mass / 58

mass ( g ) = 348 g
