I completed these, and I wanted to check if I did them correctly.
A)Write and balance equations for these reactions:
1.zinc + mercurous nitrate -->
Zn + 2HgNO3 -> Zn(NO3)2 + 2Hg
OR
2Zn + Hg2(NO3)2 -> 2Hg + ZnNO3
2.tin + antimony (V) chloride -->
Sn + SbCl4 -> Sb + SnCl4
3.calcium carbonate + hydrobromic acid -->
CaCO3 + 2HBr -> CaBr2 + CO2 + H2O
I had a lot of difficulty with this one, not sure if I am close.
B)
1. How many grams of sulphuric acid will neutralize 10.0g of sodium hydroxide?
I figured out the answer for this as 12.3 g of sulphuric acid but I am having problems with part 2.
2. What volume of water vapour at 100 'C and 110kPa would also be produced?
p = 110000 / 101325 = 1.09 atm
V = nRT / p
= 0.25 x 0.0821 x 373 K/ 1.09
= 7.02 L
Thanks.
