Answer:
C. The rate of the reaction begins to decrease as the reactants are used.
Explanation:
a p 3 x
Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
Shielding effect being attendency of the inner electrons to repel the outermost electrons, an increase in shielding effect increases atomic radius and decrease reduces the atomic radius
I think it is B
Explained answer:
Glaciers dissolve and melt because they are made out of ice
The phases of the moon occur because the moon orbits earth which causes the portion illuminated to change. The earth casts changing angles on the moon causing portions to be illuminated or dark.
