Write and balance each of the following equations, and then identify each by type.

Question

a) copper+chlorine-->copper(ll)chloride
b) calcium chlorate--->calcium chloride+oxygen
c)lithium+water--->lithium hydroxide+hydrogen
d)lead(ll)carbonate--->lead(ll)oxide+carbon dioxide
I don't know how I would even start this question and I have a test soon. Please help! Thanks in advance.:)

Answer 1

I responded to your question and I asked if you knew the four types of chemical reactions? yes or no. And what do you not understand?

Answer 2

Yes I do know them but I don't get the parts with the parentheses. What do they mean?

Answer 3

copper(II) chloride means it is coper chloride with the copper having a valence of 2. The old names were cuprous chloride for CuCl and cupric chloride for CuCl2. This new way is a way of telling you that it is copper with +2 and not copper with +1.

lead(II) oxide is the same thing. The old names were plumbous oxide for PbO and plumbic oxide for PbO2 (Pb is +4 in it).
For example, a is a way to tell you the equation is
Cu + Cl2 ==> CuCl2

Answer 4

OK thank you! I'm gonna ace this test!:)

Answer 5

Good luck!!
