Answer:
6
Explanation:
You have the unbalanced chemical reaction:
BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF
Knowing that there are 2 atoms of boron in the products, we need to adjust that element putting 2 as coefficient of BF3.
2BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF
Then, we need to balance fluor. There are 6 atoms of F in the reactants, for that reason, we write 6 in the lithium fluoride.
2BF3 + Li2SO3 ⇒ B2(SO3)3 + 6LiF
Finally, sulfur and oxygen have to be adjusted. 3 before lithium sulfite is enough to balance the chemical reaction.
2BF3 + 3Li2SO3 ⇒ B2(SO3)3 + 6LiF

I don't know the correct answer
Answer:
<h3>The answer is 0.20 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 10.686 g
volume of liquid gallium = 54.5 mL
So we have

We have the final answer as
<h3>0.20 g/mL</h3>
Hope this helps you
Answer:
(a): 2ZnO(s) -----------> 2Zn(s) + O2(g)
2C(s) + O2(g) ---------> 2CO(g)
(b): ZnO(s) + C(s) ---------> Zn(s) + CO(g)
