Answer:
carbonic acid
Explanation:
Carbonic acid refers to the natural existent acid in our atmosphere which is produced when water reacts with water vapor and it makes rain naturally acid. As a result, rainwater is always acidic. On the other hand, acid rain occurs when precipitation contains a higher than normal acidity and a pH lower than 5.0.
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
Cathode ray - a beam of electrons emitted from the cathode of a high-vacuum tube.
Beta particle - A beta particle, sometimes called beta ray <span>is a high-energy, high-speed electron or positron emitted in the radioactive decay of an atomic nucleus.
It is a subatomic particle indeed with given mass and charge.
So the answer is 4. a Gamma ray
Gamma ray - </span>Gamma rays (also called gamma radiation)<span> are penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy.</span>
True because they are organically made without any things that include chemicals
