Answer:
should be appendix, I can't see any image tho.
Just add more detail in the second experiment explain every little thing.
Distilled water has the a neutral ph. Pure water always has a ph of 7.
Answer:
-573.67
Explanation:
whenever energy is released in a chemical reaction, we would then expect the delta H of the reaction to be negative because the reaction is an exothermic reaction.
now we have that 2.81 moles of fuel when it combusts would releases 1612kJ of energy
thus, 1 mole will release 1612/2.81 = -573.67kJ of heat
Therefore the delta H of the reaction = -573.67 kJ/mol
