Chemistry
What is the mass of 0.0065 mole of ruthenium 6.5 mol Ru x101.07g Ru/1mol Ru = 0.656g Ru Or is it 0.66g Ru

Chemistry
Li(s) + N2 6Li(s) + N2 ==> 2 Li3N Li =6. Li =6 N= 2. N =2 Am I correct now

Chemistry
Li(s) + N2 6Li(s) + N2 ==> 2 Li3N Li =6. Li =6 N= 2. N =2

Chemistry
I have to put the correct complete and balanced equation for Li(s) + N2(g) Li(s) +N2(g) --- LiNi2(s) I think I'm correct what do you think

Chemistry
What is the net ionic equation for the reaction Cu(s) + 2 Ag (NO3)2(aq) --- Cu(NO3)2(aq) + 2AG(s)

Chemistry
C4H10O(l) + O2(g) --- CO(g) + H2O(g) When I balanced it I got this C4H10O(I) + 4O2(g) --- 4CO(g) + 5H2O Am I correct

Chemistry CONFUSED
I don't want the answer. Do I have to account for the molar mass of CO2 and O2.

Chemistry CONFUSED
Ok I'm really confused on the question I asked how many CO2 molecules can be made with 0.500 mol of oxygen atoms. Please help with setting this up

Math
got it. Thanks so much.

Math
is that with the requirement that each couple sit side by side?
