Answer:

Mg(s) + 2H⁺(aq) ⟶ Mg²⁺(aq) + H₂(g)  

Explanation:

A net ionic equation shows all the ionic substances as ions and shows the correct state of each substance.

B. is wrong. HCl ionizes in aqueous solution into H⁺ and Cl⁻.

C. is wrong. Mg²⁺ is not a solid. It is an aqueous ion.

D. is wrong. The equation needs 2H⁺(aq) to be balanced.

An aqueous solution of hydrochloric acid is standardized by titration with a 0.137 M solution of sodium hydroxide. If 16.1 mL of
Andre45 [30]

The molarity of the hydrochloric acid, HCl solution given the data is 0.079 M

<h3>Balanced equation </h3>

HCl + NaOH —> NaCl + H₂O

From the balanced equation above,

  • The mole ratio of the acid, HCl (nA) = 1
  • The mole ratio of the base, NaOH (nB) = 1

<h3>How to determine the molarity of HCl </h3>
  • Molarity of base, NaOH (Mb) = 0.137 M
  • Volume of base, NaOH (Vb) = 16.1 mL
  • Volume of acid, HCl (Va) = 27.9 mL
  • Molarity of acid, HCl (Ma) =?

MaVa / MbVb = nA / nB

(Ma × 27.9) / (0.137 × 16.1) = 1

(Ma × 27.9) / 2.2057  = 1

Cross multiply

Ma × 27.9 = 2.2057

Divide both side by 27.9

Ma = 2.2057 / 27.9

Ma = 0.079 M

Thus, the molarity of the HCl solution is 0.079 M

Svetradugi [14.3K]

Answer:

D.) small, dense negative nucleus surrounded by a diffuse positively charged cloud

Explanation:

I am not 100% sure but the reason I think this is the answer is because Protons and Neutrons are in the nucleus. Protons being positively charged and neutrons being negatively charged. Again, I do not know for sure, but I think D is the answer.
