Boron can be combined both with metallic elements as nonmetallic to Covalent compounds forming, since in no case give rise to Ionic States, cations (positively charged ions) or anions (negatively charged ions).
hope this helps!
Answer: 109.5g
Explanation:
Mg + 2HCl —> MgCl2 + H2
From the equation,
1mole of Mg required 2moles of HCl
Therefore 1.5moles of Mg will require = 1.5 x 2 = 3 moles of HCl.
Molar Mass of HCl = 1+35.5 =36.5g/mol
Mass conc. Of HCl = 3 x 36.5 = 109.5g
They both turn something on, and the way they are different is the way they turn it off<span>

Answer:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
