Answer: 25 moles of water are produced.

Explanation:

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

Example:  

CH_4+2O_2 \rightarrow CO_2+2H_2O

According to stoichiometry:

1 mole of methane on combustion produces= 2 moles of water

12.5 moles of methane on combustion produces= \frac{2}{1}\times 12.5=25 moles of water

Thus 25 moles of water are produced from the combustion of 12.5 moles of methane.

Which compound in the picture has a central atom with four outside atoms and has at least one nonpolar bond.
hodyreva [135]

Answer:

The answer is:

B

Explanation:

The compound in Option B is Methane.

Methane is known to be a compound which has two elements, carbon and hydrogen. It has a central atom which is surrounded by four hydrogen atoms. It's chemical formula is CH4.

Methane's outer atoms are dipoles and are in the same direction. This makes the overall molecule non-polar. The compound itself has non-polar bonds and it is non-polar itself.

The diagram shows the potential energy changes for a reaction pathway.
Nitella [24]

1) To find the change in enthalpy, determine the difference between the potential energy of the products and the potential energy of the reactants. (on this diagram, C-A) To find the activation energy, find the difference between the potential energy of the reactants and the "peak" of the curve (on this diagram, B-A). For this diagram, both the enthalpy and activation energy are positive.

2) If the reaction was exothermic, enthalpy would be negative, and the potential energy of the reactants would be greater than the potential energy of the products.
