Answer:
The charge of the ion is 2+.
Explanation:
The amount of neutrons is extra information. You just need to compare the amount of electrons to the amount of protons for the ion's charge.
In general, SOLUBILITY<span> is an ability of a substance to dissolve. In the process of dissolving, the substance which is being dissolved is called a </span>solute<span> and the substance in which the solute is dissolved is called a </span>solvent.<span> A mixture of solute and solvent is called a </span><span>solution.</span>
Proton number of a particular atom
Answer:
= 0.00325 moles of beryllium
Explanation:
Molarity or concentration is given by the formula;
Molarity = Number of moles/Volume in L
Therefore, to get the number of moles
Moles = Molarity × Volume
= 0.025 M × 0.13 L
<u>= 0.00325 moles of beryllium</u>
