I truck travel down the highway speed of 110 km/hr how long does a trip last the truck cover 2,200 km?

Answers

Answer:

20 hours

Explanation:

The time it takes for the truck to travel 2,200 km at a speed of 110 km/hr is calculated by dividing the total distance by the speed:

Time = Distance / Speed

Time = 2,200 km / 110 km/hr

Time = 20 hours

So it takes the truck 20 hours to cover the 2,200 km trip at a speed of 110 km/hr.

a. How many grams of iron (III) hydroxide were used? grams of iron (III) hydroxide (3 sig figs)

b. How many grams of iron (III) oxide were produced? grams of iron (III) oxide (3 sig figs)

Answers

The balanced equation for the reaction between iron (III) hydroxide and water vapor to produce iron (III) oxide is Fe(OH)₃ -> Fe₂O₃ + 3H₂O

a. 26.5 grams of Fe(OH)₃ used.

b. 40 grams of Fe2O3 produced

How to calculate grams used and produced?

Determine the number of moles of water produced: 0.75 L of water at STP (standard temperature and pressure) is equal to 0.75 moles.

Find the number of moles of Fe(OH)3: The reaction produces 3 moles of water for every 1 mole of Fe(OH)3, so 0.75 moles / 3 = 0.25 moles of Fe(OH)3.

Find the mass of Fe(OH)3: Fe(OH)3 has a molar mass of 106 g/mol, so 0.25 moles * 106 g/mol = 26.5 grams of Fe(OH)3.

So the answer to part a is 26.5 grams of Fe(OH)3 were used.

Determine the number of moles of Fe2O3: 0.25 moles of Fe(OH)3 produced 0.25 moles of Fe2O3.

Find the mass of Fe2O3: Fe2O3 has a molar mass of 160 g/mol, so 0.25 moles * 160 g/mol = 40 grams of Fe2O3.

So the answer to part b is 40 grams of Fe2O3 were produced.

What is a precipitation reaction?

Precipitation reactions are ones in which two aqueous solutions containing ions react to form an insoluble solid compound, which is called a precipitate. Precipitation reactions are a type of double displacement reaction, in which cations and anions exchange partners.

These reactions typically occur when two soluble salts are mixed together, resulting in the formation of an insoluble compound. Precipitation reactions are commonly used in analytical chemistry to identify the presence of certain ions in a solution.

The double displacement reaction between silver nitrate (AgNO3) and barium chloride (BaCl2) can be written as follows:

AgNO3(aq) + BaCl2(aq) -> AgCl(s) + Ba(NO3)2(aq)

In this reaction, the silver ion (Ag+) and the chloride ion (Cl-) swap partners to form insoluble silver chloride (AgCl), which precipitates out of solution. The barium ion (Ba2+) and the nitrate ion (NO3-) also swap partners to form soluble barium nitrate (Ba(NO3)2), which remains in solution.

I'll only answer the first 2 questions because there are too many questions.

1) Hydrogen basically does not really belong to Group 1 or 17 of the periodic table. To be exact, there is to such an extent that some might put it under no groups at all. Hydrogen has 1 electron in its valence shell, similar to elements in group 1. Still, it also has to gain 1 more electron to attain noble gas configuration (2 electrons for 1st shell, 8 electrons for 2nd shell). Hence, no one actually knows what hydrogen should be classified in, hence classifying it into either Group 1, 17 neither or both.

2) Mercury is the only metal that will be in liquid state at room temperature at 1 atm.

calculate the mass of sodium chlorite that must be decomposed to form 6.5g of oxygen 2NaClO3(s) —> 2NaCl(s) +3O2(g)

Answers

Answer:

14.39 g of sodium chlorite must be decomposed to produce 6.5 g of oxygen gas

Explanation:

We can start by using the balanced chemical equation for the reaction:

2NaClO3(s) -> 2NaCl(s) + 3O2(g)

This equation tells us that for every 2 moles of sodium chlorite that are decomposed, 3 moles of oxygen gas are produced. To find the mass of sodium chlorite that must be decomposed to produce 6.5 g of oxygen, we need to know the molar mass of oxygen, which is 32 g/mol.

Since 6.5 g of oxygen is equal to 6.5 / 32 = 0.203 moles of oxygen, we can use the balanced chemical equation to determine the number of moles of sodium chlorite that must be decomposed:

0.203 moles of oxygen = (0.203 moles of oxygen) / (3 moles of oxygen / 2 moles of sodium chlorite) = 0.203 * (2 moles of sodium chlorite / 3 moles of oxygen) = 0.135 moles of sodium chlorite

Finally, we can use the molar mass of sodium chlorite, which is 106 g/mol, to find the mass of sodium chlorite that must be decomposed:

0.135 moles of sodium chlorite * 106 g/mol = 14.39 g of sodium chlorite

Two solutions of different concentrations of acid are mixed creating 40 ml of a solution that is 32% acid. One-quarter of the solution is made up of a 20% acid solution. The remaining three-quarters is made up of a solution of unknown concentration, c.

Answers

The unknown concentration, c, of the acid in the remaining three-quarters of the solution is 36%.

Let x be the volume of the unknown concentration of the solution.
Then, the volume of the 20% acid solution is (40/4) = 10 ml.
We know that the total volume of the resulting solution is 40 ml, and the resulting solution is 32% acid.
This means the amount of acid in the solution is:

0.32 * 40 ml = 12.8 ml
Since we mixed 20% and c% solutions, we can set up an equation:

0.2 * 10 ml + c * x = 12.8 ml
Solving for c, we get:
c = (12.8 - 2)/x = 10.8/x

Since the volume of the unknown solution, x, is three-quarters of the total volume of the solution (40 ml),

x = 30 ml
Substituting x, we can solve for c:
c = 10.8/30 = 0.36

Therefore, the concentration of the acid in the remaining three-quarters of the solution is 36%.

How many moles are contained in 0.159 grams of aluminum sulfate, Al2(SO4)3?

Answers

0.159 grams of aluminum sulfate contains 0.000465 moles.

How to determine the number of moles of aluminum sulfate (Al2(SO4)3) in 0.159 grams

First we need to first calculate the molar mass of Al2(SO4)3.

Molar mass of Al2(SO4)3 = (2 x atomic mass of Al) + (3 x atomic mass of S) + (12 x atomic mass of O)

= (2 x 26.98 g/mol) + (3 x 32.06 g/mol) + (12 x 16.00 g/mol)

= 342.15 g/mol

Now, we can use the following formula to calculate the number of moles:

number of moles = mass / molar mass

Plugging in the values, we get:

number of moles = 0.159 g / 342.15 g/mol

number of moles = 0.000465 moles

Therefore, 0.159 grams of aluminum sulfate contains 0.000465 moles.

What are the differences between an endothermic and exothermic reaction?

Answers

Answer:

Exothermic-Producing heat

Endothermic-absorbing heat

Answer:

An endothermic reaction is a chemical reaction that absorbs heat energy, causing the temperature of the system to decrease. An exothermic reaction is a chemical reaction that releases heat energy, causing the temperature of the system to increase.

Explanation:

Hospital patients are administered oxygen from an pressurized hyperbaric oxygen chamber at 3.0 atm. 600.0 L of oxygen is compressed in a cylinder at 160.0 atm. What volume of oxygen can a cylinder supply at the given pressure?


a. 32 × 103 L

b. 32 L

c. 11 L

d. 11 × 103 L

Answers

The volume of the oxygen cylinder at a pressure of 3.0 atm is 11.25 L. The closest answer choice to this value is option C. 11 L.

How did we get the value?

We can use the ideal gas law, PV = nRT, to solve this problem. Here, P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature (assumed to be constant). Rearranging the equation, we get:

V = nRT/P

The number of moles of gas, n, can be found using the ideal gas law:

n = PV/RT

Substituting this expression for n into the equation for V and rearranging, we get:

V = PV/P = 600.0 L

So, at a pressure of 160.0 atm, the volume of the oxygen cylinder is 600.0 L. To find the volume of the oxygen cylinder at a pressure of 3.0 atm, we need to use the relationship between pressure and volume for a gas:

V1/V2 = P2/P1

Rearranging, we get:

V2 = V1 * (P2/P1) = 600.0 L * (3.0 atm / 160.0 atm) = 11.25 L

So, the volume of the oxygen cylinder at a pressure of 3.0 atm is 11.25 L. The closest answer choice to this value is (c) 11 L.

In the laboratory, a student dilutes 15.7 mL of a 11.8 M perchloric acid solution to a total volume of 200. mL. What is the concentration of the diluted solution?

? M

Answers

The concentration of the diluted solution is 0.92 M.

What is concentration?

Concentration refers to the amount of a substance present in a given volume or mass of a solution. It is typically expressed as the amount of solute per unit volume of solution or per unit mass of solvent.

To calculate the concentration of the diluted solution, we need to use the formula:

C1V1 = C2V2

where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Plugging in the values given, we get:

C1 = 11.8 M

V1 = 15.7 mL

V2 = 200 mL

We want to find C2, so we rearrange the formula to solve for C2:

C2 = (C1 x V1) / V2

Substituting the values, we get:

C2 = (11.8 M x 15.7 mL) / 200 mL

C2 = 0.92 M

Therefore, the concentration of the diluted solution is 0.92 M.

How does the amount of energy coming from the energy source (low vs. high) affect the amount of electrical energy released.

If (A. more), (B. less) energy is put into the system, then (A. more), (B. less) energy will be released from the system.

Answers

The quantity of electrical energy released is a function of the quantity of energy coming from the energy source (low vs. high). The system will release (A) more (B) less energy depending on how much energy is introduced into it.

What is the use of electrical energy in the system?

The rotor shaft of a generator is spun or rotated by the fluid's force on the blades. The generator then transforms the kinetic (mechanical) energy of the rotor into electrical energy.

Turbines come in a variety of forms, including steam, combustion (gas), hydroelectric, and wind turbines.

At the scale that a large utility would use them, solar and wind power are currently the least expensive sources of energy. They are much less expensive than coal and nuclear power plants and slightly less expensive than natural gas-fired power plants.

Therefore, Depending on how much energy is supplied into the system, it will either (A) release more (B) or less (C).
