Will someone let me know if I did these correct?
1. Rank the following in order of increasing radius based on their positions on the periodic table: S, S-2, Cl
a. S, S-2, Cl
b. S-2, Cl, S
c. Cl, S, S-2
d. Cl, S-2, S
e. S, Cl, S-2
I believe it's C. Cl, S, S-2
Is that correct, did I do that right?
2. Methane burns in oxygen according to the following equation:
CH4(g) + 2O2(g)----> CO2(g) + 2H2O
What is the mass of CO2 produced when 3.4 grams O2 react according to the above equation?
I did this and got C. 2.3g, is that correct, did I do that right?
Thanks in advance for the help ;-)
I gave hints at the original post. I think these answers are ok.
