Answer:
Explanation:
You can't award 20 points once you have awarded 5.
One
2K + Cl2 ==> 2KCl
It's True
There are 2 Ks and Cl2 has 2 atoms making up on the left.
On the right, 1 molecule of KCl has 1 Potassium and 1 Cl. But there are 2 molecules so between the two of them, there's 2 Potassiums and 2 Cl
Two
The reactant side is the Left side. Cl2 means there are 2 Cl atoms making Cl2. Answer B
Three
False: There are 2 but read below.
I really don't know how to answer that. It's not qualified enough. There are a total of 2 Chlorines on the right hand side when there are 2 molecules. I think you are intended to answer False, but don't be surprised if you get it wrong.
Answer:
C3H6
Explanation:
We can obtain the molecular formula by using the empirical formula and the molar mass in combination.
This is shown below:
[CH2]n = 42g/mol
We then add the atomic masses of carbon and hydrogen and multiply by n to give the value of n .
n[12 + 2(1)] = 42
14n = 42
n = 42/14 = 3
The molecular formula is thus [CH2]3 = C3H6
