Question

c) Calculate the amount of heat released when 15.5g of carbon reacts d) What mass of carbon must react to produce 1575 kJ of heat? 3) For the reaction: 2 Li + F2 → 2 LiF a) What mass of LiF will be formed is 10.5 g of Li reacts with 37.2 g of F2? b) What is the limiting reactant? c) If 21.0g of LiF is actually produced, what is the percent yield? 4) For the reaction: SO3 + H2O + H2SO4 A chemist allows 61.5g of SO3 and 11.2g of H2O to react. When the reaction is finished, the chemist collects 54.9g of H2SO4. Determine the limiting reactant, theoretical yield, and percent yield.
someone please answer these questions :)

Answer 1

first find the moles and then identify the limiting reactant and then calculate the theoretical yield and the percent yield is as follows
