Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) ½h2(g) + ½i2(g) → hi(g), δh = +6.2 kcal/mole 21.0 kcal/mole + c(s) + 2s(s) → cs2(l) what type of reaction is represented by the previous two examples?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
