Question

2 attempts left Check my work Be sure to answer all parts. (a) Write a balanced equation for the reaction depicted below. Do not include states. Si N SiH,+N,F.--SiF , +N2+2H, (b) If each reactant molecule in the above image represents 0.0350 mol and the reaction yield is 80.%, how many grams of Si-containing product form? 2.9

this equation was also incorrect! thanks so much for your help :)

Answer 1

a) Balanced equation will be 3 Si HA + 3 N2 FA - 3 sifa + 3N2 + 6H2 OST, Si ha & No fa sifa + N2 + 24₂ O from the equation it is clear that 1 mole will reeact with Imole Ne fa and will produce 1 mole si H sifa Here mole of silta = mole of No FA mole = 0.0 350 yield is 80%. :. product will be sifa (0:095*0'3) = 0.02.80 mole Molecular weight of sifa (1984)= 10ug/mol 28+ 0.0 28 mode = (0:02 *X104) 2:912 g cont ain silicon 2.912 g product will forin aing
