Explanation:
a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.
Yes
b. There are no attractive forces and repulsive forces between gas molecules.
Yes
C. Atoms are neither created nor destroyed by ordinary chemical reactions.
No
d. The volume occupied by all of the gas molecules in a container is negligible compared to the volume of the container
Yes
The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.
According to the theory;
- The temperature of gas is proportional to the average kinetic energy.
- Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
- volume occupied by gases is negligible compared to the volume of the container.
Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

The specific heat capacity the substance is calculated using the below formula
Q(heat) = Mc delta T
Q =1560 cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?
by making c the subject of the formula
c=Q/m delta T
= 1560 cal/ 312g x 15 c = 0.33 cal/g/c (answer B)
<span>Bonds of reactants are broken and create new bonds to form different products and produces exothermic and endothermic reactions.

Answer:
True
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
