From the reaction, the volume of the oxygen required is 89.6 L.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with the process by which the mass of reactants or products in a reaction is obtained from the balanced reaction equation.
In this case, the balanced reaction is equation is;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Number of moles of CO2 = 88.0 g/44 g/mol = 2 moles
2 moles of O2 produced 1 mole of CO2
x moles of O2 produces 2 moles of CO2
X = 4 moles
1 mole of oxygen occupies 22.4 L hence 4 moles of oxygen occupies 4 * 22.4 L = 89.6 L

Answer:
0.10 % w/w
Explanation:
The percent by mass (%w/w) is defined as one hundred times the ratio between the mass of solute (In this case aspirin, 0.05g) and the mass of solution (Mass solute + mass of water = 0.05g + 50g = 50.05g). The percent by mass is:
0.05g Aspirin / 50.05g * 100 =
0.10 % w/w
Answer:
this is very easy to solve
- (NH4)2 Co3,(NH4)2 So4,( NH4)3 Po4
- k2 co3, k2 so4,k3 Po4
- zn oh2, zn (No3)2, zn3 (Po4)
- ca oh2
- fe oh3, fe(No3)3, fe2 (co3)3, fe2 (so4)3
this is a answer I am very sure
Propene is the unsaturated compound.
Explanation:
In the presence of sulphuric acid (H₂SO₄), propanol will eliminate one water molecule (H₂O) to form propene, which is the unsaturated compound.

a solution is two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (ex: sugar). The solvent is the one doing the dissolving (ex: water).
i learned this in science last year i hope this helped :)
