Baking soda neutralizes the acid so D
Answer:
When zinc metal is reacted with hydrochloric acid, hydrogen gas is released and an aqueous solution of zinc chloride is produced. ... It is important that all of the zinc used be reacted and that large excess amounts of hydrochloric acid not be used.
Anhydrous zinc chloride is synthesized by treating zinc with hydrogen chloride. Whereas, hydrated and aqueous forms of zinc chloride are prepared by treating zinc with hydrochloric acid. Zinc metal could either be in the form of zinc sulfide or zinc oxide

Answer:
The enthalpy of the reaction of the chlorine with ozone is -162.5 kJ/mol.
Explanation:
...(1)
...(2)
...(3)
The enthalpy of reaction for the reaction of chlorine with ozone can be calculated by using Hess's law:
(2 )- (1) = (3)
The enthalpy of the reaction of the chlorine with ozone is -162.5 kJ/mol.
Sulfuric acid, H₂SO₄, and potassium hydroxide, KOH reaction is called
neutralization and results to the formation of salt and water through the
chemical equation,
H₂SO₄ + KOH --> K₂SO₄ +
H₂O
The chemical reaction can be balanced through the multiplying the
compounds by a numerical coefficient to achieve equal number of atoms of
certain element on the left-hand side and right-hand side of the equation.
<span> <em>H</em></span><em>₂SO₄ + 2KOH --> K₂SO₄ + 2H₂O</em>
<em>
</em>The balancing of the equation can be checked if correctly done if the
number of the atoms of the elements are equal.

The answer to your question is below
Explanation:
Data
Aqueous sodium carbonate = Na₂CO₃ (aq)
Aqueous strontium chloride = SrCl₂ (aq)
Solid strontium carbonate = SrCO₃ (s)
Aqueous sodium chloride = NaCl (aq)
Unbalnced Chemical reaction
Na₂CO₃(aq) + SrCl₂(aq) ⇒ SrCO₃(s) + NaCl(aq)
