Gaining of electrons is reduction and loss of electrons is oxidation.

Answer:
2.At a given temperature, the KE of all gases is the same.KE depends only on Kelvin temperature
Explanation:
The kinetic molecular theory of gases provides a succint expalantion and insight into the behaviour of gases. The assumptions of the theory are stated below:
- Gases are made up of large number of identical molecules which are moving at different speeds.
- Spaces occupied by molecules of gases are negligible compared to the volume of the container.
- Molecules of gases are independent of one another.
- The molecules collide with themselves and the walls of the container elastically.
- The temperature of a gas is a measure of only the average kinetic energy of the molecules.
Answer:
n= -13
Explanation:
-22 = -9 + n
first flip the equation
n + -9 = -22
then add 9 beacuse we need to do the opposite to find n
so -22 + -9 = - 13
so n = -13
plz mark brainliest i just need 1 more plz plz plz!
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties. It also depends on what your doing to the soap
Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water. things burning or exploding. Would be chemical reactions Examples of physical changes include crushing a can, melting an ice cube, and breaking a bottle.
