Alpha decay
Beta Decay (@chickenfingers is correct, thank you)
go to http//mathway.com There you will find the best online problem solving (free) software that I have seen. (I have a masters in nuclear/particle physics and still use it from time to time with great satisfaction).

This is an example of beta decay, specifically beta-minus decay. In this reaction, a neutron in the nucleus is transformed into a proton, electron, and anti-neutrino. This results in the formation of 90Zr from 90Y.

Nuclear fission
Nuclear fission reactions involve the splitting of atomic nuclei to release energy, while nuclear fusion reactions involve combining atomic nuclei to release energy. Both types of reactions are seen in nuclear power plants and stars.
You see it every day, it's called the sun:)
Acid plus carbonate produces carbon dioxide gas, water, and a salt. This reaction is a chemical reaction known as neutralization. The carbon dioxide gas is the most visible product, often seen as bubbles.
That process is called a chain reaction. In a chain reaction, the products of one reaction act as reactants in the subsequent reactions, leading to a self-sustaining series of reactions. This can result in a rapid release of energy, as seen in nuclear reactions or certain chemical reactions.
The mass is not lost but transformed in energy.
I assume it was seen as more positive.
In a reversible reaction, the products can convert back into the reactants given appropriate conditions. This is often seen in chemical equilibrium where the forward and reverse reactions occur at the same rate.
Burning is a chemical reaction (oxidation).
