Explanation:
thermal changes are those in which heat exchange is involved like endothermic and exothermic
while in chemical changes collision between the reactant occurs which result into product
Answer:
A. The gas molecules possess kinetic energy.
Explanation:
The characteristics of the Ideal gases are given by the Kinetic Theory of gases which are as follows:-
Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
Gas pressure is due to the molecules colliding with the walls
7 moles of oxygen are in the sample.
According to the chemical formula, each mole of nickel tetracarbonyl contains 4 moles of C atoms. Simply convert it into a fraction by putting the original solution in the denominator and the diluted solution in the numerator if you need to determine the concentration ratio between two solutions. The V/n ratio for each gas must be the same if the two gases are at the same temperature and pressure. The volume ratio of two gases at the same temperature and pressure is equal to their molar ratio. The mole ratio of C to O is 1 : 1

1 mole of any particles = 6.02* 10²³ particles
4.5*10²⁵ atoms Ni* 1 mol Ni/6.02*10²³ Ni ≈ 74.75≈ 75 mol Ni
Its A) Shared equally
Non-polar bonds are a type of chemical bond where two atoms share a pair of electrons with each other.
