Someone please help and explain, I only need c and d done Using values from Appendix C, calculate the standard enthalpy change for each of the following reactions:
(a) 2 SO2(g) + O2(- 2 SO3(g)
(b) Mg(OH)2(s) - MgO(s) + H2O(1)
(c) CH (8) + 4Cl2(g) — CCI (1) + 4 HCI(g)
(d) SiCl4(1) + 2 H2O(l) —— SiO2(s) + 4 HCl(g)

Does the temperature affect the solubility of sugar and salt in water? if it does tell me like different temperatures with different solubilities so i can sketch down a graph

Which of the following best explains why the end of a spoon sticking out of a cup of hot water also gets hot? question 7 options: the heat from the hot water is conducted through the spoon handle the hot water heats the air surrounding the upper part of the spoon. the hot water causes a physical change in the spoon handle. the hot water causes a chemical reaction to take place in the spoon.
