659. 48 g of water is produced
Answer: 1 mole of 
has the greatest mass.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP , contains avogadro's number 
of particles and weighs equal to the molecular mass of the substance.
1 mole of has a mass of 40 g.
1 mole of 
has a mass of 28 g
1 mole of 
has a mass of 32 g
1 mole of 
has a mass of 16 g.
1 mole of 
has a mass of 30 g.
Thus the greatest mass is of 1 mole of
Answer:
250ml
Explanation:
call it V
V*0.2=0.05 (moles)
so V=0.05/0.2 = 0.25l = 250ml
Answer:
Yes. Burning usually observes this kind of law.
Explanation:
- The law of conversion of mass states that mass can never be formed nor can it be eradicated.
- This means that in case of burning, the amount of matter before and after will remain to be the same.
- It doesn't change at all.
- In conclusion, there's no form of change that can be able to affect matter.
Answer:
4P + 5O₂ —> P₄O₁₀
Explanation:
From the question given above, we obtained:
P + O₂ —> P₄O₁₀
The above equation can be balance as illustrated below:
P + O₂ —> P₄O₁₀
There are 4 atoms of P on the right side and 1 atom on the left side. It can be balance by 4 in front of P as shown below:
4P + O₂ —> P₄O₁₀
There are 10 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 5 in front of O₂ as shown below:
4P + 5O₂ —> P₄O₁₀
Now the equation is balanced.
