Question

Given the following chemical equation, determine how many grams of N2 are produced by 9.72 g of H2O2 and 6.53 g of N2H4

Answer 1

Where is the equation? And please spell chemistry right next time.

Answer 2

2H2O2(l)+N2H4(l)=4H2O(g)+N2(g)

Answer 3

This is a limiting reagent (LR) problem and you know that because amounts are given for BOTH reactants. First, make sure the equation is balanced.
mols H2O2 = grams/molar mass = ?
mols N2H4 = grams/molar mass = ?

Next, using the coefficients in the balanced equation, convert mols H2O2 to mols N2 produced.
Do the same and convert mols N2H4 to mols N2.
These two values for mols N2 are likely to be different; the correct answer in LR problems is ALWAYS the smaller value and the reagent responsible for that smaller value is called the LR.
Using that value, grms N2 = mols N2 x molar mass N2.
