The number moles of carbon dioxide 31.2 moles will be produced when 10.4 mol of propane gas is burned in excess oxygen.
A mole would be the amount of a material that includes exactly 6.02214076 × of the particular chemical elementary constituents.
It is known that the formula of propane is .
The chemical reaction of propane.
+
→
It can be understand that, the ratio of propone and carbon di-oxide is 1:3.
The moles of propane = 10.4 mol
So, number of moles of = 10.4 mol × 3 =31.2 mol.
Therefore, the number of moles of carbon di-oxide will be 31.2
Hence, the correct answer will be option (C).

Explanation:
(in scientific vocab)
my guess i dont know exactly but heat is energy
heat absorbed or radiated during a change of phase at a constant temperature and pressure. specific heat. the heat required to raise the temperature of one gram of a substance one degree centigrade. heat of condensation. heat liberated by a unit mass of gas at its boiling point as it condenses into a liquid.
The reaction will proceed in the forward direction to reach equilibrium.
To determine which reaction will go in order to reach equilibrium, we need to compare the initial number of moles of reactants to the stoichiometric coefficients of the balanced equation. The balanced equation for the reaction between NH₃, N₂, and H₂ is:
NH₃ + N₂ ↔ 2NH₃
Since the initial number of moles of NH₃, N₂, and H₂ are the same (1.00 mole each), the reaction will proceed in the forward direction to reach equilibrium.

B 16g/56g x 100%
C 40g/56g x 100%
D 40g/100% x 56g
Answer:
C 40 g/56 g × 100 %
Explanation:
Calculate the mass of each component and the total mass.
Element Atomic mass/u No. of atoms Subtotal mass/u
Ca 40.08 1 40.08
O 16.00 1 16.00
Total = 56.08
The formula for mass percent is
% by mass = Mass of component/Total mass × 100 %
In this problem
% Ca = mass of Ca/mass of CaO × 100 %
% H = 40.08 g/56.08 g × 100 %
The percentage composition of calcium (Ca) in CaO is option C.
Element Atomic mass/u No. of atoms Subtotal mass/u
Ca 40.08 1 40.08
O 16.00 1 16.00
Total = 56.08
Therefore, we can conclude that the correct option is C.
