Liquid pentane (c5h12) reacts with gaseous oxygen to form carbon dioxide and liquid water. express your answer as a chemical equation. identify all of the phases in your answer.

The balanced chemical equation is written below.

Explanation:

Combustion reactions are defined as the chemical reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water. Heat is released during these reactions.

The chemical equation for the combustion of pentane follows:

By Stoichiometry of the reaction:

1 mole of liquid pentane reacts with 8 moles of gaseous oxygen to produce 5 moles of carbon dioxide gas and 6 moles of liquid water.

Hence, the balanced chemical equation is written above.

the atomic mass is the bottom number on the element.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
