What substance is a reactant, along with oxygen, in cellular respiration?

Cellular respiration is a process in which energy is generated by burning of glucose in presence of oxygen.

The energy generated during cellular respiration is used to carry of different cellular functions .

During this process along with energy, carbon dioxide (CO2) and water vapors are also generated,

The process can be represented as follows.

Glucose + Oxygen ------> Carbon dioxide + water + Energy

Therefore, Glucose ( C₆H₁₂O₆) is a reactant, along with oxygen, in cellular respiration

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
