Exothermic reaction

Explanation:

In an exothermic reaction the products enthalpy is lower than the reactants because in an exothermic reaction the heat is released to the surroundings.

An endothermic reaction occurs the opposite, the products have a higher enthalpy than the reactants, because it absorbs the heat from the surroundings.

Reactions between liquids and between solids, can be either exothermics or endothermics

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
