Help PLEASE 20 POINTS NEED SOON (10 Points) Given the information in the table above, calculate the ΔHorxn for the following chemical reaction:
3Al(s) + 3 NH4ClO4(s) → Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O(g)

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x.xx ml

50 pts plz what is the physical state of matter of baking soda.
