in the reaction, 2 li (s) + cl2 (g) imported asset 2 licl (s), the reducing agent is:

the li

the cl2

the licl

both the li and the cl2

Correct answer is Li

Explanation:

Lithium reacts with chlorine to form Lithium chloride.

This is a redox (Oxidation -Reduction) reaction

Hence the reducing agent in this reaction is Li

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%
