EASY 100 POINTS, WILL MARK BRAINLEST, 2 QUESTIONS, SHOW YOUR WORK OR NO POINTS

If it's easy then why don't you do it?

Explanation:

1 c. enthalpy change = enthalphies of formation of all products - enthalphies of formation of all reactants =  -526.3 kcal/mol

1 d. C3H8(g) + 5 O2 (g) → 3 CO2 (g)  + 4 H2O (l)    ΔH = -526.3 kcal/mol

is there multiple choice answers?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
