4 As water and sulfuric acid are mixed together the temperature of the mixture becomes very hot. Select the statements
that best describe why this happens. Assume that both substances start out at room temperature and there is no
external heat source affecting them.
AA chemical reaction is occurring.
Energy is released during the chemical reaction.
C Energy is absorbed during the chemical reaction.
D No chemical reaction occurs because water is inert.
E The lack of a chemical reaction causes the temperature to increase.

A chemical reaction is occurring and energy is released.

Explanation:

Heat is released when you combine a strong acid with water, considered exothermic. That's why it's extremely important to add the acid to a large volume of water; not vice versa.

Halogens (group 17) are very reactive because they need only one electron to fulfil their noble gas configuration. ... They will steal electrons from where ever they can to get that configuration. They are also very electronegative due to the increased effective nuclear charge compared to other elements

I hope that i helped you brother

Thank me by pressing heart ❤️
