Desertification:Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid.
Deforestation: the action of clearing a wide area of trees.
Climate change: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years.
Extinction:
the state or process of being or becoming extinct.
The pressure of a gas is the force that a gas exerts per unit area of the container.
Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.
Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.
The volume of a container refers the size if the container.
The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.
For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.
For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.

Answer:
K2CO3 = K2O + CO2
Explanation:
In a chemical equation, the number of atoms on the left needs to be balanced with the number of atoms on the right, and there has to be the same number of the same *type* of atom on both sides as well.
On the left:
2 K
1 C
3 O
and on the right,
2 K
1 O
On the right, there are a few atoms missing, specifically, 1 C and 2 O.
The missing atoms then should be added to the side missing the atoms, preferably in a stable molecule. Luckily, CO2 contains exactly 1 C, and 2 O s, and is quite stable. So, a "CO2" has to be added on the left
Answer:
In my opinion, I think its 2
