How many grams of ammonia can be made by reacting 100 g of N2 with 20 g of ? What is the limiting reactant? How much of the excess reactant will be left over? N2(g) + 3H2(g) → 2NH3(g)
Molar mass of N2 = 28.0134100/28.0134 = 3.57molesMolar ratio of N2:NH3 = 1:23.57 × 2 = 7.14moles of NH3Molar mass of H2 = 2.01620/2.016 = 9.92molesMole ratio of H2:NH3 =...

Calcium reacts with nitrogen. Calculate the mass of the product that is formed when 127.56 g of calcium reacts with 149.52 g of nitrogen. Identify your limiting reactant on this question.
3Ca + N2 --------> Ca3N2moles of calcium present = 127.56/40.078= 3.183 molesmoles of N present = 149.52/14.0067= 10.675 molesFrom the above equation, 3 moles of Ca are needed to completely react...

1. Considering the following reaction: 3Si + 2n2 →Si3N4 2. When 26.8 moles of Si react with 21.845 moles of N2, how many moles of Si3N4 are formed? 3. What is the limiting reactant?
Mole ratio of Si:Si3N4= 3:1= 26.8/3= 8.933Mole ratio N2: Si3N4=2:1= 21.845/2= 10.923= 10.923+8.933= 19.856moles

In a chemical reaction, your limiting reactant was used up. You have a large quantity of excess reactant remaining. Will the reaction procees? Why or why not?
No, we don't have all reactants required for the reaction, so it wouldn't proceed.

Determine the limiting reactant when 3g of ammonia reacts with 6g of oxygen to produce H2O and nitrogen monoxide
4NH3 +5 O2 --> 4NO +6H2Ois the balanced reaction mass of NH3 present = 3 gmols of NH3 present = 3 g/17.03 g/mol = 0.1762 molmass of O2 present = 6gmols of O2 present = 6 g/32 g/mol...

Considering the limiting reactant, what is the volume of NO gas produced from 60.0 L of ammonia gas and 50.0 L of oxygen gas? (Assume constant conditions.)
4 NH3(g) + 5 O2(g) 4 NO(g) + 6 H2O(g)
Volume of reactants is proportional to coefficient in equation. So for this reaction we need correlation of volumes NH3 : O2 like 4:5 and we have 60:50,so NH3 is in...

calculate the mass of 2.4 moles of ammonia, NH3
answer: __grams
A student performing this reaction makes 8.5 grams of ammonia, NH3. How many moles of ammonia did she make?
answer:__moles
Solution:The molar mass of NH3 is 17.031 g/mol.Hence,a) Mole to Grams conversion:2.4 mol NH3 × (17.031 g NH3 / 1 mol NH3) = 40.8744 g NH3 = 40.87 g NH3Answer...

2HCl + Mg → MgCl2 + H2
If we use 12grams of HCl and 8grams of Mg, which is the limiting reactant, and which reactant is excess?
n(HCl) = m/M = 12g/36.5g/mol = 0.329 moln(Mg) = 8g/24g/mol = 0.333 molAccording to the equation 1 mol of Mg reacts with 2 mol of HCl. HCl is the limiting...
