hydrogen chloride gas and oxygen react to form water vapor and chlorine gas. What volume of water would be produced by this reac
1 answer:
Answer : The volume of water produced by this reaction would be, 4.75 liters.
Explanation : Given,
Volume of HCl gas = 9.5 L
The balanced chemical reaction will be:
As we know that at STP, 1 mole of gas occupy 22.4 L volume of gas.
By the stoichiometry we can say that:
As, 4 liter volume of HCl gas react to give 2 liter volume of water
So, 9.5 liter volume of HCl gas react to give volume of water
Therefore, the volume of water produced by this reaction would be, 4.75 liters.

Phosphorus trifluoride is formed from its elements.
How many grams of fluorine are needed to react with 6.20 g of phosphorus?
Answer : The mass of needed are, 11.4 grams.
Explanation : Given,
Mass of = 6.20 g
Molar mass of = 124 g/mol
Molar mass of = 38 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 1 mole of react with 6 moles of
So, 0.05 moles of react with
moles of
Now we have to calculate the mass of
Therefore, the mass of needed are, 11.4 grams.
