Qualitative I believe is right
Ead sulfide + oxygen lead oxide + sulfur dioxide
2 PbS(s) + 3 O2(g) 2 PbO(s) + 2 SO2<span>(g)
Hope this is what you are asking for :))</span>
Answer:
It is C.
Explanation:
The atomic mass = number of protons + number of neutrons
= 5 + 6 = 11. The number of protons = the number of electrons.
Answer : The volume of required is, 60 L
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical reaction will be:
From the balanced chemical reaction we conclude that,
As, 1 mole of completely react with 2 moles of
So, 0.3 mole of completely react with moles of
Now we have to calculate the volume of required.
Therefore, the volume of required is, 60 L
