Answer:
Oxygen
Explanation:
<em>Oxygen. </em>Based on octet rule (An empirical rule that refers to the tendency of atoms to prefer to have eight electrons in the valence shell giving the same electronic configuration of a noble gas), the Sulfur and oxygen need two electrons to complete eight electrons in its valence shell, giving, in this way, the same electronic configuration as Ne and Ar, respectively.

The change in enthalpy associated with the change in the water’s temperature is 1254 J.
<h3>What is specific heat?</h3>
The amount of heat required to increase the temperature of one gram of a substance by one Celsius degree is known as specific heat.
Enthalpy change will be calculated as:
ΔH = -cmΔT, where
m = mass of water = 50g
c = specific heat of water = 4.18J/g°C
ΔT = change in temperature = 28 - 22 = 6 °C
On putting values in the above equation, we get
ΔH = -(4.18)(50)(6) = -1254 J
Hence change in enthalpy of the reaction is -1254 J.
