Answer:
Last option C(s) + O2(g) → CO2(g)
Explanation:
The reactions are:
2Ca(s) + Cl2(g) → CaCl2(s)
4Mg(s) + O2(g) → 2MgO(s)
Li(s) + Cl2(g) → 2LiCl(s)
C(s) + O2(g) → CO2(g)
Let's count the atoms (check out the stoichiometry):
1. We have 2 Ca in reactant side and 2Cl, in product side we have 1 Ca and 2 Cl. UNBALANCED
2. We have 4 Mg in reactant side and 2 O. In product side we have 2 Mg and 2 O. UNBALANCED
3. In reactant side we have 1 Li and 2 Cl. Then, in product side we have 2Li and 2Cl. UNBALANCED
C(s) + O2(g) → CO2(g)
1 C and 2 O ⇒ 1 C and 2 O Correctly balanced

Answer: military
African Americans received the best treatment in the military during war. Making up about 3/4 of the military, African American soldiers proved their efficiency and ability to serve the country, thus receiving more respect from society than if they were to work in more "common" jobs, for example in a factory. However, while they received the best treatment in the military during the war, African Americans still faced segregation within the units of the military, an important fact to note.
one US ton is 2000 lbs, thus 2/5 of that is just their product.
answer: 800 lbs
