Chemical equation represents a redox reaction :
2Li + MgCl₂ → 2LiCl + Mg
<h3>Further explanation</h3>
The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number
Reaction
2Li + MgCl₂ → 2LiCl + Mg
Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Answer:
The answer to your question is The honda civic hybrid weights 13181.8 N or 1318.2 kg
Explanation:
Data
Weight = 2900 lb
Weight = ? N
mass = ? kg
1 kg ------- 10 N
0.22lb ---- 1N
Use proportions to solve this problem
                         0.22 lb ------------------- 1 N
                         2900 lb -----------------  x
                          x = (2900 x 1) / 0.22
                          x = 2900 / 0.22
                          x = 13181.8 N
                           1 kg ----------------------- 10 N
                            x     ----------------------- 13181.8 N
                            x = (13181.8 x 1)/10
                            x = 1318.2 kg
