In short, I’d say the answer is C.
In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.
1) Chemical equation
H2 (g) + Br2 (g) ---> 2 HBr
2) molar ratios
1 mol H2 : 1 mol Br2 : 2 moles HBr
3) convert 30.0 g of H2 to number of moles
moles = mass in grams / molar mass = 30.0 g / 2.02 g/mol = 14.85 moles
4) calculate theoretical yield
2 moles HBr / 1 mol H2 = x / 14.85 moles H2
=> x = 14.85 moles H2 * 2 moles HBr / 1 mol H2 = 29.7 moles HBr
5) convert 59.52 moles HBr to mass
mass = number of moles * molar mass = 29.7 moles * 80.91 g /mol = 2403.03 g
6) percent yield = (actual yield / theoretical yield) * 100 = (85.00g / 2403.03g)*100 = 3.54%
Answer: 3.54%
I’m pretty sure true, just not your skull at birth hehe. hope this helps :)
