1. Ammonia
Step-by-step explanation:
Ammonia, NH₃, is a <em>compound</em> of nitrogen and hydrogen.
Thus, it can be broken down by chemical means into the <em>elements</em> nitrogen and hydrogen.
The other options are <em>wrong</em>, because Al, Sb, and Pb are elements. They cannot be broken down chemically into simpler substances.
Answer:
Option B is correct. A nuclear alpha decay
Explanation:
Step 1
This equation is a nuclear reaction. So it can be an alpha decay or a beta decay
An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4.
During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less.
Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation that is showed.
A Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
Option B is correct. A nuclear alpha decay
