M (O) = M x n
M (O) = 16g/mol
n (O) = 3 x n (NaHCO3)
n (NaHCO3) = m/M
m (NaHCO3) = 0.72g
M (NaHCO3) = 23 + 1 + 14 + 16 x 3 = 86g/mol
n (NaHCO3) = 0.72/86 = 0.008372mol
n (O) = 3 x 0.008372 = 0.02512
m (O) = 16 x 0.02512 = 0.402g
First, if you want to get the amount of production from the equation, you need to use the units of mol. So, we need to know the molar mass of C which is 15.75/12=1.31 mol. Then we need to use the less part(O2) to get the production amount which is 0.116 mol. Then we can get the answer in units of g: 0.116*(12+16*2)=5.104 g.
Answer:
Hydrogen and fluorine form only one bond while carbon forms four bonds to other atoms.
Explanation:
This question brings us to the idea of valency. Fluorine is univalent while carbon is tetravalent.
Univalent means that fluorine can only form one bond to hydrogen while carbon forms as much as four bonds because it is tetravalent.
Hence fluorine and hydrogen have only one peg while carbon has four.
