General Formulas and Concepts:
Chemistry
Synthesis Reactions: A + B → ABDecomposition Reactions: AB → A + BSingle-Replacement Reactions: A + BC → AB + CDouble-Replacement Reactions: AB + CD → AD + BCExplanation:
Step 1: Define
2C₂H₂ + 5O₂ → 2H₂O + 4CO₂
Step 2: Identify
Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.
We also see from the RxN that is is a double replacement reaction.

0.4 g
Explanation:
1) Balanced chemical equation:
2) 2C2H2 + 5 O2 → 4CO2 + 2 H2O
3) mole ratios:
2 mol C2h2 : 5 mol O2
4) Convert 0.13 g C2H2 into number of moles
n = mass in grams / molar mass
molar mass C2H2 = 2 *12g/mol + 2*1 g/mol = 26 g/mol
n = 0.13 g / 26 g/mol = 0.005 mol
5) Set the proportion with the unknown
5 mol O2 x
=
2 mol C2H2 0.005 mol C2H2
x = 0.005 mol C2H2 * 5 mol O2 / 2 mol C2H2 = 0.0125 mol O2
6) Convert 0.0125 mol O2 to grams
mass = number of moles * molar mass
molar mass of O2 = 32 g/mol
mass = 0.0125 mol * 32 g/mol = 0.4 g
0.4 g

Ответ:
Ans: Maximum amount of Fe produced = 5 moles = 280 g
The given reaction is:
Fe2O3 + 2Al → Al2O3 + 2Fe
Moles of Fe produced with respect to Fe2O3:
Based on stoichiometry, 1 mole of Fe2O3 produces 2 moles of Fe
Therefore, for the given 3 moles of Fe2O3, amount of Fe produced
= 3*2 = 6 moles
Moles of Fe produced with respect to Al:
Based on stoichiometry, 1 moles of Al produces 1 mole of Fe
Therefore, for the given 5 moles of Al, amount of Fe produced = 5 moles
Here, since Al produces less moles of Fe, Al will be the limiting reagent. Therefore, maximum moles of Fe produced = 5 moles
Atomic mass of Fe = 56 g/mol
Mass of Fe produced = 5 moles * 56 g/mol = 280 g
