Question

If 25.0 grams of sodium reacts with 50.0 grams of water. What is the balanced equation, how many grams of sodium hydroxide is produced, what volume of hydrogen gas is produced, which reactant is in excess and by how much in grams, and if only 5.0 grams of sodium hydroxide is produced what is the percent yield?

Answer 1

2Na+2H₂O=2NaOH+H₂

mass of sodium hydroxide 55.5g

sodium is excess reagent

yield = 9%
