Answer 1

Answer:

2 temperature increases

Answer 2

Answer:

Answer is option 1) (i) & (iv)

Explanation:

because acid and base are mixed to give salt and water. This process is exothermic in nature giving out heat called as heat of neutralization which causes an increase in temperature. So, these reactions can be explosive in nature when acid is added to any base and this raises the temperature of acid-base reactions.
