mcq of chemical reaction and equation

Formation of ammonia is an example of 1. endothermic reaction 2. exothermic reaction 3. both (1) and (2) 4. none of these

The bond energy required to break one mole of HCl is 1. 103 kcal 2. 104 kcal 3. 44 kcal 4. 300 kcal

An example for naturally occurring endothermic reaction is 1. respiration 2. electrolysis of water 3. photosynthesis 4. none of these

The energy required in breaking a mole of H-H bond is 1. 104 kcal 2.62 kcal 3.57.8 kcal 4. 10.3 kcal

Internal energy of a substance depends on 1. number of atoms present in a molecule 2. number of molecules present in a substance 3. chemical structure and physical state 4. none of these

Energy stored in the molecules is known as 1. Heat energy 2. Light energy 3. Internal energy 4. Kinetic energy

Volume - Volume relations use a hypothesis proposed by 1. boyle 2. charles 3. gaylussac 4. avogadro

Chemical equation represents the shorthand notation of 1. only the reactants present in the chemical change 2. only the reactants products in the chemical change 3. all reactants and products present in a chemical change 4. only volumes of gases at S.T.P

Weight - Volume relations used the concept 1. Volume occupied by one mole of gas at 30 c and 1000 mm of Hg pressure 2. Volume occupied by one mole of a gas of STP 3. Volume occupied by two moles of gas at STP 4. Volume occupied by one mole of liquid at S.T.P.
