If I have 10.0g of Mg, what is my theoretical yield of MgCl2

Answers

Answer 1

Explanation:

First, let's write the balanced equation of formation of MgCl2 from Mg and Cl2:

Mg + Cl2 → MgCl2

Now let's transform 10.0g of Mg into moles, using the following formula: moles = mass/molar mass

molar mass of Mg = 24.3 g/mol

moles = 10/24.3

moles = 0.412 moles

Now we use the equation ratio between Mg and MgCl2 to find the quantity of MgCl2 in moles.

1 mole of Mg produces 1 mole of MgCl2.

So 0.412 moles of Mg produces 0.412 moles of MgCl2.

Now we transform 0.412 moles of MgCl2 into mass using the following formula: mass = moles x molar mass

Molar mass of MgCl2: 24.3 + (2*35.45) = 95.21 g/mol

Mass = 0.412 * 95.21

Mass = 39.2 g

Answer: The theoretical yield of MgCl2 is 39.2 g.

calculate the number of litres of each gas givin the following number of moles at STPhow many litres of gas is in 0.001 mol H2S

Answers

STP stands for Standard Temperature and Pressure. Nowadays the STP is temperature of 0°C (273.15K) and pressure of 1 bar.

Assuming the gas behaves as an ideal gas, in these conditions the volume of each mol of gas is approximately 22.7 L.

Using rule of three, we can calculate the volume of 0.001 mol of H₂S:

Volume --- Number of moles

x --- 0.001 mol

22.7L --- 1 mol

[tex]\begin{gathered} \frac{x}{22.7L}=\frac{0.001}{1} \\ x=22.7\cdot0.001L \\ x=0.0227L \end{gathered}[/tex]

So, the volume is approximately 0.0227 L.

Which compound results from covalent bonding? AgF K2S NaCl CO2

Answers

Answer:CO2

Explanation:

A trick that is quick and easy to use when telling covalent bonds from ionic bonds is to look at the atoms that are bonding. If there is a metal involved, then it is ionic bonding (hence AgF, NaCl. and K2S are not covalent bonding as Ag, Na, and K are all metals.

But to be more specific, ionic bonding happens when two ionic or polar atoms (atoms with non-neutral charges,) come together to balance out their charges (as negative charges will be attracted to positive charges and vice versa); the fancy term for this is electrostatic forces. They (usually) give up electrons to another atom, but do not share electrons. Covalent bonding happens when atoms actually share electrons and have their atomic orbitals overlap, meaning that the electrons actually travel through the surrounding volume of both atoms. Ionic bonded atoms will also separate into ions when in a solvent.

A gas mixture contains 1.26 g N2 and 0.76 g O2 in a 1.51 L container at 11 C. Calculate the partial pressure of N2?

Answers

When we have a mixture of gases, the pressure exerted by each depends on the number of moles present in the mixture, this contribution is called partial pressure. The sum of the partial pressures will be equal to the total pressure, this is called Dalton's law.

Partial pressure can be described by the following equation:

[tex]P_i=X_iP_T[/tex]

Where,

Pi is the partial pressure

Xi is the molar fraction

Pt is the total pressure

The molar fraction is calculated by the following equation:

[tex]X_i=\frac{n_i}{n_T}[/tex]

Where,

ni is the number of moles of the substance

nT is the total number of moles.

So, we have to find first the number of moles of each gas. We are given the grams of gases, to get the equivalent moles we must divide the mass by the molar mass.

Molar Mass N2=28.0134g/mol

Molar Mass O2=31.9988g/mol

[tex]\begin{gathered} molN_2=1.26g\times\frac{1molN_2}{28.0134gN_2}=0.045molN_2 \\ molO_2=0.76gO_2\times\frac{1molO_2}{31.9988gO_2}=0.024molO_2 \end{gathered}[/tex]

Now, the partial pressure of N2 will be:

[tex]P_{N2}=\frac{0.045molN_2}{0.045molN_2+0.024molO_2}\times P_T[/tex][tex]P_{N2}=\frac{0.045molN_2}{0.069mol}\times P_T[/tex][tex]P_{N2}=0.652\times P_T[/tex]

If we assume that the gas behavior is like an ideal gas, we can find the total pressure with the following equation:

[tex]\begin{gathered} PV=nRT \\ P_T=\frac{nRT}{V_T} \end{gathered}[/tex]

Where,

n is the total number of moles, 0.069mol

R is a constant, 0.08206atm.L/mol.K

V is the volume of the gas, 1.51L

T is the temperature of the gas, K.284.15K

We replace the known data:

[tex]P_T=\frac{0.069mol\times0.08206\frac{atm.L}{mol.K}\times284.15K}{1.51L}=1.06atm[/tex]

Now, the partial pressure of nitrogen will be:

[tex]P_{N2}=0.652*1.06atm=0.69atm[/tex]

Answer: The partial pressure of N2 is 0.69atm

Answers

Answer:

[tex]C\text{ : -0.44 KJ}[/tex]

Explanation:

Here, we want to get the amount of heat released in KJ

From the change in enthalpy given and the equation of reaction, we know that 2 moles of HBr would lead to that amount of heat

Now, let us get the actual amount of heat released

We need to get the actual number of moles of HBr produced

Mathematically, we can calculate that by dividing the mass of HBr by its molar mass

We have that as:

[tex]\frac{0.989}{80.91}\text{ = 0.0122 mol}[/tex]

From the reaction information:

-72 KJ was released by 2 moles

x KJ would be released by 0.0122 mol

To get the value of x, we have it that:

[tex]\begin{gathered} x\text{ }\times2\text{ = 0.0122 }\times\text{ \lparen-72\rparen} \\ \\ x\text{ = -36 }\times\text{ \lparen0.0122\rparen = -0.44 KJ} \end{gathered}[/tex]

Answers

We have the concentration of H+ ions, from these concentrations we can find the pH values of the solutions with the following equation:

[tex]pH=-log\lbrack H^+\rbrack[/tex]

Where [H+] is the concentration of H+ ions.

Now, the acidity or basicity of a solution depends on the pH value. A solution above 7 will be basic, below 7 will be acidic, and equal to 7 will be neutral.

Let's determine the pH value for each solution:

[tex]\begin{gathered} pH=-log\lbrack4.3\times10^{-3}mol/L\rbrack \\ pH=2.4 \end{gathered}[/tex][tex]\begin{gathered} pH=-log\lbrack9.8\times10^{-12}mol/L\rbrack \\ pH=11.0 \end{gathered}[/tex][tex]\begin{gathered} pH=-log\lbrack4.8\times10^{-2}mol/L\rbrack \\ pH=1.3 \end{gathered}[/tex]

So, we have that:

A. [H+] = 4.3 × 10-3 mol/L. pH=2.4. Acidic

B. [H+] = 9.8 × 10-12 mol/L pH = 11.0 Basic

C. [OH-] = 4.8 × 10-2 mol/L pH=1.3 Acidic

Since we live in a modern industrialized world, we need to get exposed to lots of chemicals and pollutants. With modernization people began to use Air conditioners, Refrigerants, and other household appliances for a sophisticated lifestyle without knowing the harmful effects it causes on the environment.

The use of Refrigerators and Air Conditioners contains Freons which are used as aerosol propellants. These freons release CFCs which are called as Chloro-Fluro-Carbons which are the main element responsible for damaging the environment by causing both global warming and Ozone depletion.

The Chlorine atom that is released from the CFCs breaks the bond of the Ozone. The reaction is elucidated below:

ClO + O -------> Cl + O₂

This breaks the bond of Ozone creating Ozone depletion and eventually leading to Global Warming.

Similar to Ozone depletion, another main environmental problem is the greenhouse effect which is occurring mainly due to the release of harmful gases from automobiles, and industries such as CO₂, SO₂, etc... These gases absorb and trap the solar heat from the Infrared region and creates a greenhouse effect. These gases are called greenhouse gases.

This greenhouse effect, ozone depletion eventually leads to an increase in global temperature and results in the rising of sea levels by melting the glaciers and icebergs. The climatic pattern is adversely affected. This would affect agriculture, as well as the health of humans as harmful UV rays that enter the earth due to ozone depletion, will lead to skin  diseases, cancer, and so on.

By adversely affecting the agriculture and health of the world, there would be a drop in the entire economy as our country is dependent mainly on agriculture for the nation's economy.

The effects of these could be minimized by using public transport, planting trees, using refrigerators and air conditioners free from freons, and proper treatment of the wastes eliminated from industries must be ensured.

A) 69.4% B)93.0 % C) 96.94% D)98,22 %

Answers

Answer:

[tex]C\text{ : 96.94 \%}[/tex]

Explanation:

Here, we want to get the percentage by mass of calcium carbonate in the limestone

We start by writing an equation of chemical reaction

The reaction involves calcium carbonate reacting with hydrochloric acid to give calcium chloride, carbon dioxide and water

We have the equation as follows:

[tex]\text{CaCO}_{3(s)\text{ }}+2HCl_{(aq)}\rightarrow CaCl_{2(aq)\text{ }}+CO_{2(g)\text{ }}+H_2O_{(l)}[/tex]

Now, let us work with the extra information

16.89 g of calcium chloride are produced

Let us get the number of moles of calcium chloride produced

We can get that by dividing the mass by the molar mass of calcium chloride

The molar mass of calcium chloride is 111 g/mol

So, the number of moles will be:

[tex]\frac{16.89}{111}\text{ = 0.1522 mole}[/tex]

From the equation,

1 mole of calcite gave 1 mole of calcium chloride, then 0.1522 mole of calcium chloride was produced by 0.1522 mole of calcite

To get the mass of calcite that produced this, we have to multipply the number of moles by the molar mass of calcite

The molar mass of calcite is 100 g/mol

That means the mass of calcite that produced the calcium chloride will be:

[tex]0.1522\text{ }\times\text{ 100 = 15.22 g}[/tex]

What this mean is that 15.22 g of calcite produced the given mass of calcium chloride

The percentage by mass of calcite in the limestone will be:

[tex]\frac{15.22}{15.70}\times\text{ 100\% = 96.94 \%}[/tex]

C2H4 + 3O2 ——> 2CO2 + H2OWhat volume of oxygen at STP is needed to react with 5.75 mol of C2H4 (Show all work and data charts)

Answers

Explanation:

C₂H₄ + 3 O₂ ——> 2 CO₂ + H₂O

According to the coefficients of the equation 1 mol of C₂H₄ will react with 3 moles of O₂. Then, the molar ratio between C₂H₄ and O₂ is 1 to 3. We can use that relationship to find the number of moles of oxygen that are needed to react with 5.75 moles of C₂H₄.

1 mol of C₂H₄ = 3 moles of O₂

moles of O₂ = 5.75 moles of C₂H₄ * 3 moles of O₂/(1 mol of C₂H₄)

moles of O₂ = 17.25 moles

One mol of a gas at STP always occupies 22.4 L. We can use that relationship to find the volume of oxygen.

1 mol of O₂ = 22.4 L

volume = 17.25 moles of O₂ * 22.4 L/(1 mol of O₂)

volume = 386.4 L

Answer: 386.4 L at STP is needed to react.
