The number located in the top right corner of the ion is +2
An ion is an atom or group of atoms which possess an electric charge.
The charge on an ion can be obtained by using the following formula:
<h3>Charge = Proton – Electron </h3>
With the above formula, we can obtain the charge of the ion given in the question above as illustrated below:
Proton = 16
Neutron = 17
Electron = 14
<h3>Charge =? </h3>
Charge = Proton – Electron
Charge = 16 – 14
<h3>Charge = +2</h3>
Therefore, the charge on the ion is +2

Answer: the first option is correct
Why: the seed is the one doing all the work and no other forces were mentioned after 4 days
<u>Answer:</u> The correct option is C) 1.68 mol/L
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Given mass of 
= 150 g
Molar mass of = 180 g/mol
Volume of the solution = 0.50 L
Putting values in equation 1, we get:
Hence, the correct option is C) 1.68 mol/L
