The total reaction energy calculated by reactant bond energy - product
bond energy
The reactant bond energy is usually higher than that of the product bond
energy. This is as a result of the bonds in the product having higher bond
energy than the reactants.
<h3>What is Total reaction energy?</h3>
The total reaction energy is therefore calculated by subtracting the product
bond energy from the reactant bond energy so as to know the net energy
which was used in the reaction.

<span>Following are important postulates of Kinetic theory of gases
1) Gases are made up of number of particles.
this particles behaves like hard and spherical objects, which are in constant state of motion.
2) The particles always travel in a straight line until they collide with another particle or the walls of the container.
3) Particles are of smaller size as compared to the distance between particles.
4) There exist minimal/no force of attraction between the gas particles neither there exist attractive interaction between the particles and the walls of the container.
5) Collisions between gas particles or with the walls of the container are elastic in nature.
Thus, statement a i.e. </span><span>Gas particles have a high force of attraction to one another or to the walls of the container contradicts the postulates of kinetic theory of gases</span>
Answer:
The statement correctly predicting and explaining the chemical reactivity of two metals is given below -Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons
Explanation:
C.
This is also the only change by which crystals may be produced.
Because its in group one....which only lose or gain electrons.....thus it will only have oneelectron to fulfill its octect rule
