When the enthalpy of products is higher than that of reactants, such a reaction is said to be endothermic.
<h3>Enthalpy</h3>
The enthalpy of a system refers to the heat content of the system.
When the enthalpy of reactants is higher than that of products in a reaction, such a reaction is said to be exothermic. On the other hand, if the enthalpy of products is higher than that of the reactants, it is endothermic.

Transverse waves. Transverse waves occur when a disturbance causes oscillations perpendicular (at right angles) to the propagation ( the direction of energy transfer).
The number of moles of gas present are 0.0054
<u>Explanation:</u>
Given-
Temperature, T = 100°C = 100 + 273 = 373K
Volume, V = 0.044L
Pressure, P = 3.81 atm
Moles of gas, n = ?
We know,
PV = nRT
R = 0.082 L.atm.K⁻¹.mol⁻¹
n = PV/RT
n = (3.81)(0.044)/(0.082)(373)
n = 0.0054 moles
Therefore, number of moles of gas present are 0.0054
