Storm clouds being formed will most likely occur in this scenario.

<h3>What are Storm clouds?</h3>

These are formed during the process of convection in which heat and moisture is transported upward into the atmosphere.

We were told that the weather is warm and cold air will enter the region which means that it will replace the heat and moisture as they move upwards thereby resulting in the formation of storm clouds.

Consider the half reactions below for a chemical reaction.

ladessa [460]

Answer:

Option A:

Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)

Explanation:

The half reactions given are:

Zn(s) → Zn^(2+)(aq) + 2e^(-)

Cu^(2+) (aq) + 2e^(-) → Cu(s)

From the given half reactions, we can see that in the first one, Zn undergoes oxidation to produce Zn^(2+).

While in the second half reaction, Cu^(2+) is reduced to Cu.

Thus, for the overall reaction, we will add both half reactions to get;

Zn(s) + Cu^(2+) (aq) + 2e^(-) → Cu(s) + Zn^(2+)(aq) + 2e^(-)

2e^(-) will cancel out to give us;

Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)

Isotopes of carbon differ with the respect to the number of

hodyreva [135]

Answer:

Neutrons.

Explanation:

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

The isotope of an element is denoted by $X^{A}_{Z}$

Where; X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Therefore, the number of neutrons = A - Z

Isotopes of carbon differ with respect to the number of neutrons.

Basically, there are three (3) Isotopes of Carbon and these are;

1. Carbon-12: it has an atomic mass of 12 with 6 numbers of proton and neutron respectively.

2. Carbon-13: it has an atomic mass of 13 with 6 numbers of proton and 7 numbers of neutron.

3. Carbon-14: it has an atomic mass of 14 with 6 numbers of proton and 8 numbers of neutron.
