Ireland maintains Honorary Consulates in Mumbai, Kolkata, Chennai and Bengaluru. significant number of Irish people joined the British civil service and the army regiment during the nineteenth century. Additionally, Irish missionaries, educationalists, medical and engineering service professionals were also posted in India during this period.
Enthalpy of a reaction or energy change of a reaction D H, is the amount of energy or heat absorbed in a reaction. If the energy is required, D H is positive, and if energy is released, the D H, is negative.
This is called an endothermic reaction. When enthalpy is negative and delta H is less than zero, this means that a system released heat. This is called an exothermic reaction. In chemistry, the system in question is the set of compounds in a reaction or process. Delta H describes whether this system absorbs or emits heat.
