how many grams of H2 (g) are produced by the reaction of 1.35 g Al with 75.0 mL of 3.44 M HCl Here is the way to do most of these stoichiometry/limiting reagent type problems. Step 1. Write a balanced chemical equation. 2Al + 6HCl
from the balanced equation 4NH3 +7O2 - 4NO2 + 6H2O How many molecules of water are produced when 2.25 moles of ammonia are completely reacted? The equation tells us that 4 mol NH3 will produce 6 mols water. That means 2 mols NH3
This problem of the limiting reactant is: Given the reactant amounts specified in each chemical reaction, dtermine the limiting reactant in each case: (I'm just going to take one problem out of the bunch} HCl + NaOH yeilds NaCl +
I just can't do this... Two moles of potassium chloride and three moles of oxygen are produced from the decomposition of two moles of potassium chorate. What is the balanced equation? How many moles of oxygen are produced from
so in order to find out how many moles of O2 are produced from 12 moles of KClO3: 2 mols KClO3 form 3 mols O2 4 mols KClO3 form ? mols O2 Do you double the mols of O2 4 mols KClO3 form 6 mols O2? 6 mols KClO3 form 9 mols O2
Determine the number of grams of NH3 produced by the reaction of 3.5g of hydrogen gas with sufficient nitrogen gas. All of these stoichiometry problems are work almost the same. Sometimes an extra step or two are required. Here
How many grams of hydrochloric acid are required to react completely with 4.30g of zinc? How many molecules of gas will be produced? 1. Write the balanced chemical equation. Zn + 2HCl ==> ZnCl2 + H2 2. Convert grams Zn to mols.
Determine the volume of oxygen that is needed at STP to completely react with 5.63 g of potassium. 4K + O2 yields 2H2O I don't buy the equation. If K is reacting with oxygen, then the equation is 4K + O2 ==> 2K2O Actually, I
I don't know how to do this How many moles of water can be made from 4 moles of oxygen gas and 16 moles of hydrogen gas? What is the limiting reagent? Write the balanced equation. 2H2 + O2 ==> 2H2O 2 mols H2 + 1 mol O2 will
If 20.0 grams of Al is placed into a solution containing 115 grams of H2SO4, how many grams of hydrogen gas could be produced? 1. Write the balanced equation. 2Al + 3H2SO4 ==> Al2(SO4)3 + 3H2 2. Convert 20.0 g Al to mols.
