I have solved your problem
Explanation:
<span>No. Salt, like all matter is composed of atoms.</span>
Answer:
See Below.
Explanation:
Recall that molarity is defined by moles of solute over liters of solution (mol/L).
Therefore, to make 90.0 mL of 2.0 M MgSO₄, we will need:

Convert this amount to grams. The molecular weight of MgSO₄ is 120.38 g/mol:

Therefore, to make the solution, we can add 22 grams of MgSO₄ into a graduated cylinder, then mix and dilute the solution with distilled water until we reach 90.0 mL.
Answer: Covalent Bond
Explanation:
Covalent bond is the type of chemical bond between two atoms that are connected to each other by the sharing of two or more electrons. example is the bond between Dinitrogen
