Percentage Yield HW Question

Hi, I'm having trouble solving problem M1 in the homework. This is the equation given: 2NH3+ClO->N2H4+Cl+H2O. 35g of ammonia and an excess of hypochlorite ions were combined to create 25.2g of hydrazine. What is the percentage yield of hydrazine? I know that I must divide the mass of each reactant b...

Balancing Chemical Equations

Hello, I am having trouble solving problem H17 of the homework.

Balance C7H16->CO2H2O.

Finding moles of one element in a compound

I'm having some trouble finding the moles of one specific element in a compound. For example, in homework problem E23b, find moles of SO3 in 7x10^2mgSO3. First, I converted 7x10^2mgSO3 into grams and got .7gSO3. Then I divided .7gSO3 by its molar mass, 80.066 and got .0874mol SO3. Is this method cor...

Re: Study Tips

Dr. Lavelle and his TA's have set aside many study hours outside of lectures and discussions!! They're almost daily, both on campus and on the hill, how convenient!! Thank you Dr. Lavelle!

Re: Rusty on High School Chem [ENDORSED]

I'm in the same boat, maybe worse! I haven't taken general chemistry since sophomore year and I feel so behind! Trying my best to catch up and review basic high school chem topics but I feel so lost ):
