Ineed with the bottom chart and the three questions at the bottom would be greatly appreciated : )

• 1/1000 | 1/100 | 1/10 | 1 | 10 | 100 | 1000 |
• 0.0016 | 0.016 | 0.16 | 1.6 | 16 | 160 | 1600|
• 14 | 140 | 1400 | 14000 | 140 000 | 1 400 000 | 14 000 000 |
• 0.109 | 1.09 | 10.9 | 109 | 1090 | 10900 | 109000|
• 0.25 | 2.5 | 25 | 250 | 2500 | 25000 | 250000|
• 56cm < 6m
• 200cm = 2m
• 7g > 698 mg

Explanation:

The given data is as follows.

   Density of vinegar = 1.0 g/ml

   Specific heat capacity = 4.25

    = ,  and   =

Relation between enthalpy and specific heat is as follows.

                   

Hence, putting the values into the above formula as follows.

         

                  =          (as density = )

                               = - 315 J

Thus, we can conclude that the enthalpy of reaction is -315 J.

As the value is negative so, it means that heat is releasing. Hence, the reaction is exothermic in nature.
