Hydrochloric acid and sodium hydroxide neutralise each other and the pH resulting solution will be 7.
Table salt is a compound because Sodium (Na) and Chlorine (Cl) were combined to make a new group.
- Answer:
Energy release is exothermic reaction whiles energy absorb is endothermic reaction
Explanation:
Exothermic reaction is when the reactant is above the product while endothermic the product is below the reactant in the diagrams we have some part as activation energy
Find your answer in the explanation below.
Explanation:
PV = nRT is called the ideal gas equation and its a combination of 3 laws; Charles' law, Boyle's law and Avogadro's law.
According to Boyle's law, at constant temperature, the volume of a gas is inversely proportional to the pressure. i.e V = 1/P
From, Charles' law, we have that volume is directly proportional to the absolute temperature of the gas at constant pressure. i.e V = T
Avogadro's law finally states that equal volume of all gases at the same temperature and pressure contain the same number of molecules. i.e V = n
Combining the 3 Laws together i.e equating volume in all 3 laws, we have
V = nT/P,
V = constant nT/P
(constant = general gas constant = R)
V = RnT/P
by bringing P to the LHS, we have,
PV = nRT.
