What two general products do combustion reactions

Reaction of combustion, always generate CO₂ and H₂O, with O₂ as a reactant.

Explanation:

The combustion reaction is a type of exothermic chemical reaction, where carbon dioxide and water are generated, as products. It is an exothermic reaction where heat is released and a flame is formed. When combustible substances react to the maximum possible degree of oxidation, we speak of complete combustion.

This is the combustion for methane:

CH₄ (g)  + 2O₂(g)  →  CO₂(g)  +  2H₂O (g)

This is the combustion for propanol

2C₃H₇OH (l)  +  9O₂(g)  →  6CO₂(g)   +   8H₂O (g)

This is the combustion for acetic acid

CH₃COOH (l)  +   2O₂(g)  →  2CO₂(g)   +  2H₂O (g)

the maximum mass of nh3 is nh3 in grams

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
