Calcium carbonate can break down to form calcium oxide and carbon dioxide. caco3 → cao + co2 the oxygen atoms on the product side are not balanced because there are only two oxygen atoms in co2 not balanced because there is only one oxygen atom in cao. balanced because the total number of oxygen atoms is 3. balanced when a coefficient of 3 is placed in front of co2.

balanced because the total number of oxygen atoms is 3.

Explanation: CaCO3 → CaO + CO2

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
