The melting point of gallium is 85.59°F (29.77°C).
The statement that is true regarding the atom that has a charge of +1 in its nucleus for it to have no net charge is that there is one negatively charged electron outside the nucleus (option B).
<h3>How is net charge formed?</h3>
An atom is made up of three subatomic particles namely;
- Proton; which is the positively charged particle
- Electron; which is the negatively charged particle
- Neutron
The number of protons and electrons in the atom is responsible for the net charge of that atom. For example, if there are more protons than electrons, the atom will be positively charged.
However, according to this question, an atom has a charge of +1 in its nucleus. This means that for this atom to have no net charge i.e. 0, there must also be one electron orbiting outside the nucleus.
Therefore, the statement that is true regarding the atom that has a charge of +1 in its nucleus for it to have no net charge is that there is one negatively charged electron outside the nucleus.

Answer: 2 Acetate ions
Explanation:
Strontium Acetate, has the molecular formular to be; C4H6O4Sr ( or in a linear form, Sr(CH3COO)2), contains two acetate ions.
Answer: The Process is Deposition
Explanation:
According to this equation:
AgCl(s) ↔ Ag+(aq) + Cl-(aq)
so K1 = [Ag+][Cl-]
when [Ag+] = [Cl-] we can assume both = X
and when we have X the solubility = 1.33 x 10^-5 mol / L
by substitution:
∴ K1 = X^2
= (1.33 x 10^-5)^2
= 1.77 x 10^-10
by using vant's Hoff equation:
ln(K2/K1) = (ΔH/R)*(1/T2-1/T1)
when ΔH = 65700 J / mol
R = 8.314
T1 = 25+273 = 298 K
T2 = 47.7 +273 =320.7
by substitution:
∴㏑(K2/1.77 x 10^-10) = (65700/8.314) * ( 1/320.7 - 1/ 298)
by solving for K2
∴K2 = 2.7 x 10^-11
and when K2 = X^2
∴ the solubility X = √(2.7 x 10^-11)
= 5.2 x 10^-6 mol/L
