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>

Explanation:
Why the ratio of dioxygen to carbon dioxide is 1:2 on the basis of moles, i.e. on the basis of number of particles .
Answer:
A. 0.48mol O2
Explanation:
The balanced equation is given as follows:
2CH3OH + 3O2 → 2CO2 + 4H2O
This shows that 2moles of CH3OH is required to react with 3 moles of O2
If 0.32 moles of CH3OH are reacted, then;
0.32 × 3/2 moles of O2 is required
= 0.96/2
= 0.48mol of O2

Answer:
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
