Chemistry => Stoichiometry => Limiting reactant
The maximum number of molecules that can be formed will depend on the limiting reactant. The limiting reactant corresponds to the reactant that produces the least amount of product, or in other words, the one that is completely consumed in the reaction.
To find the limiting reactant we are going to divide the moles of each reactant by the stoichiometric coefficients of the balanced equation, the reactant with the lowest ratio will be the limiting reactant.
The balanced equation for this reaction will be:
We have, according to the image the following number of molecules:
Xe=2molecules
F2=4molecules
The limiting reactant will be:
Both reactants are limiting reactants. We can take any reactant and we will have the same number of molecules of XeF4 formed. The ratio Xe to XeF4 is 1/1, so the molecules of XeF4 that can be formed will be:
Answer: 2 XeF4 molecules
Answer:
The answer to your question is:
a) 3.87 mol of CO2
b) 14.63 mol of O2
Explanation:
2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(g)
a)
CO2 = ?
Butane 0.968 moles
From the balance equation 2 moles of butane ---------- 8 moles of CO2
0.968 moles of butane ------ x
x = (0.968 x 8) / 2
x = 3.87 moles of CO2
b)
moles O2 = ?
butane = 2.25 mol
From the balance equation
2 moles of butane ---------- 13 mol O2
2.25 mol ---------- x
x = (2.25 x 13) / 2
x = 14.63 mol of O2
Answer: 2. Decomposition
Explanation:
Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
lithium carbonate → lithium oxide + carbon dioxide
Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A double replacement reaction is one in which exchange of ions take place.
