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: Zirconium [Kr]4d :)
Explanation:
Answer:
D
Explanation:
Option D is the correct Lewis structure of ozone.
Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.
In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.
The correct answer would be we have no other frame of reference besides the sky. We could actually tell we are moving because of the shifting of stars in the sky over time. But really, “A” would be your answer. We have the same momentum of the earth. It’s like being on a train at a constant speed. The only way you know you’re moving is if you look out the window or the speed changes causing you to be pushed around. Same thing with earth, our only reference is the sky
