Determine the mass of CO2 produced by burning enough of methane to produce 1.50×102kJ of heat. CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rx

MArishka [77]

Answer: The mass of $CO_2$ produced will be 8.228 g.

Explanation:

We need to find the mass of carbon dioxide produced when 150 kJ of heat is released.

For the given chemical reaction:

$CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g);\Delta H^o_{rxn}=-802.3kJ$

By Stoichiometry of the reaction:

802.3 kJ of energy is released when 1 mole of carbon dioxide is produced.

So, 150 kJ of energy will be release when = $\frac{1}{802.3}\times 150=0.187mol$ of carbon dioxide is produced.

To calculate the mass of carbon dioxide, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Moles of carbon dioxide gas = 0.187 mol

Molar mass of carbon dioxide gas = 44 g/mol

Putting values in above equation, we get:

$0.187mol=\frac{\text{Mass of carbon dioxide gas}}{44g/mol}\\\\\text{Mass of carbon dioxide gas}=8.228g$

Hence, the mass of $CO_2$ produced will be 8.228 g.

Determine how many atoms of pure silver will be created when 19.83 x 1023 atoms of copper are used in the following reaction:

nadezda [96]

Answer : The number of silver atoms produced will be $39.66\times 10^{23}$

Explanation : Given,

Number of atoms of copper = $19.83\times 10^{23}$

The given balanced chemical reaction,

$Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$

From the balanced chemical reaction we conclude that,

As, $6.02\times 10^{23}$ number of copper atoms react to give $2\times 6.02\times 10^{23}$ number of silver atoms.

So, $19.83\times 10^{23}$ number of copper atoms react to give $2\times \frac{6.02\times 10^{23}}{6.02\times 10^{23}}\times 19.83\times 10^{23}=39.66\times 10^{23}$ number of silver atoms.

Therefore, the number of silver atoms produced will be $39.66\times 10^{23}$

Calculate the molarity of the two solutions. The first solution contains 0.650 mol of NaOH in 1.35 L of solution.

Serjik [45]

Answer:

0.481 M

Explanation:

The molarity ratio looks like this:

Molarity = moles / volume (L)

Since you have been given both the mass and volume, you can plug them into the equation to find the molarity.

Molarity = moles / volume

Molarity = 0.650 moles / 1.35 L

Molarity = 0.481 M
