In the reaction of magnesium metal with hydrochloric acid, we can determine that the magnesium metal has reacted completely when the magnesium metal is gone.
<em>In the reaction of magnesium metal with hydrochloric acid, how do you determine when the magnesium metal has reacted completely? select all that apply.</em>
- <em>All of the water has evaporated. </em>
- <em>The dilute HCl is gone. </em>
- <em>The magnesium metal is gone. </em>
- <em>Gas bubbles are no longer produced.</em>
Magnesium reacts with hydrochloric acid according to the following equation.
Mg(s) + 2 HCl(aq) ⇒ MgCl₂(aq) + H₂(g)
How can we determine when the magnesium metal has reacted completely?
All of the water has evaporated. NO. Water is not part of the reaction.
The dilute HCl is gone. NO. It indicates that HCl reacted completely.
The magnesium metal is gone. YES. If Mg is gone means it reacted completely.
Gas bubbles are no longer produced. NO. The bubbles, produced by hydrogen, may not be produced due to the insufficiency of HCl.
In the reaction of magnesium metal with hydrochloric acid, we can determine that the magnesium metal has reacted completely when the magnesium metal is gone.

Answer:
what grade are you in and i think it is D
Explanation:
a. double replacement
b. AB + CD ⇒ AD +CB
c and d
H₃PO₄ : Phosphoric acid
KOH : Potassium hydroxide
K₃PO₄ : Tripotassium phosphate
H₂O : water
<h3>Further explanation</h3>
Given
Reaction
H₃PO₄ + 3 KOH → K₃PO₄ + 3 H₂O
Required
Type of reaction
General equation
Name of reactants and product
Solution
Double replacement reaction : Cations and anions of different compounds switch places
It can also be said as <em>a neutralization reaction</em> because it produces water(reaction between an acid and a base)
AB + CD ⇒ AD +CB
- Name of reactants and products
H₃PO₄ : Phosphoric acid
KOH : Potassium hydroxide
K₃PO₄ : Tripotassium phosphate
H₂O : water
