Explanation:
From the image given;
Number of Protons = 1
Number of Electrons = 1
Number of Neutrons = 0
Positive Charge (From the protons) = + 1
Negative charge (From the electrons) = -1
Atomic mass = Mass of Proton + Mass of Neutron = 1.00727647 amu + 0.000549 amu = 1.00784 amu
Overall Charge = Positive charge + Neutral charge = 1 -1 = 0 (Neutral atom)
<span>Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.
You didn't list any options, but I hope this helps!

CaF2 or calcium fluoride occurs naturally in nature and is sometimes called mineral fluorite or fluorspar.
Based on the given molecular formula, the molar mass of ethylene glycol is 62 g/mol. We solve for the number of moles of the solute,
n = (7.1 kg)(1000 g/ 1 kg) / 62g/mol = 114.52 mol
Then, we divide this value by the given mass of the water in kg
m = (114.52 mol) / 1.2 kg = 95.43 m
Thus, the molality of the substance is approximately equal to 95.43 m.
