When 500.0 g of water is decomposed by electrolysis and the yield of hydrogen is only 75.3%, how much hydrogen chloride can be m

Evgen [1.6K]

The amount of hydrogen chloride that can be made is 1064 g

Why?

The two reactions are:

2H₂O → 2H₂ + O₂ 75.3 % yield

H₂ + Cl₂ → 2HCl 69.8% yield

We have to apply a big conversion factor to go from grams of water (The limiting reactant), to grams of HCl, the final product. We have to be very careful with the coefficients and percentage yields!

$500.0gH_2O*\frac{1moleH_2O}{18.01 gH_2O}*\frac{2 moles H_2}{2 moles H_2O}*\frac{2.015g H_2}{1 mole H_2}*\frac{75.3 actual g}{100 theoretical g}=42.12 g H_2$

$42.12H_2*\frac{1 mole H_2}{2.015gH_2}*\frac{2 moles HCl}{1 mole H_2}*\frac{36.46g}{1 mole HCl}*\frac{69.8 actualg}{100 theoreticalg} =1064gHCl$

Have a nice day!

Which unit conversion allows you to convert 21.0 gallons into milliliters?

Romashka-Z-Leto [24]

79470.2mL

Explanation:

Given:

Volume = 21gallons

problem, convert to milliliters;

gallons to milliliters

1 liter = 1.057 quarts

1 gallon = 4 quarts

we can simply solve this by establishing and using a conversion factor of 1 ;

1 gallon = 4 quarts

1.057 quarts = 1 liter

0.001L = 1mL

21gallons x $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$ = 79470.2mL

we say;

From; $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$

1gallon = 3784.2mL

To improve air quality and obtain a useful product, chemists often remove sulfur from coal and natural gas by treating the conta

Norma-Jean [14]

Answer:

1) Increase

2) Decreases

3) increases

4) Increase

Explanation:

These questions can only be answered by considering the principle which states that, "When a constraint such as a change in concentration, pressure or volume is imposed on a reaction system in equilibrium. The system will readjust itself in order to annul the constraint."

Now, if more reactants are added, the equilibrium position will shift towards the right, If more products are added, the equilibrium position will shift to the left.

Similarly, the removal of H2S causes the O2 concentration to increase since the equilibrium position now shifts to the left.

Also, addition of O2 causes H2S to be removed as the equilibrium moves to the right.
