(10 Points) Given the information in the table above, calculate the ΔHorxn for the following chemical reaction: (SHOW ALL WORK!)
3Al(s) + 3 NH4ClO4(s) → Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O(g)
Arock can be broken down into different kinds of substances by physical processes. no chemical reactions are needed to separate different parts of a rock into pure substances. this is because a rock is a(n)
