Answer:
55.1 g Si.
Explanation:
Hello there!
In this case, for the given mole-mole relationship, it is possible to set up the following mole ratio as the moles of Si and P are the same:
1 mol Si = 1 mol P.
Next, since one mole of silicon has a mass of 28.09 g and one of phosphorous of 31.0 g, we can set up the following expression for the mass of silicon:
Therefore, the result is 55.1 grams of silicon.
Best regards!
I think it would increase but I may be wrong
M=6.58 g
ρ=0.7899 g/ml
v=m/ρ
v=6.58g/(0.7899g/ml)=8.33 ml

Explanation:
2) The chemical reaction is:
2 Na + I₂ → 2 NaI
Na - sodium
I - iodine
In this reaction there are 2 reactants and 1 product.
The reaction is balanced.
3) The chemical reaction is:
N₂ + O₂ → 2 N₂O
N - nitrogen
O - oxygen
In this reaction there are 2 reactants and 1 product.
The reaction is not balanced, the balanced reaction is:
2 N₂ + O₂ → 2 N₂O
4) The chemical reaction is:
N₂ + 3 H₂ → 2 NH₃
N - nitrogen
H - hydrogen
In this reaction there are 2 reactants and 1 product.
The reaction is balanced.
5) The chemical reaction is:
2 KI + Cl₂ → 2 KCl + I₂
K - potassium
I - iodine
Cl - chlorine
In this reaction there are 2 reactants and 2 products.
The reaction is balanced.
