The correct answer should be
<span>At dynamic equilibrium, the rates of forward and reverse reactions are equal.
The chemicals keep exchanging but the rates are the same which means that the chemicals move at an equal rate.</span>
Answer:
- Not balanced.
- Reactants: Zn and HCI
.
- Products: ZnCl₂ and H₂.
- Substitution reaction.
Explanation:
Hello,
In this case, for the given reaction:
Zn + HCI → ZnCl₂ + H₂
We can see that it is not balanced due to the fact that at the left side we have one hydrogen atom whereas at the right side two, taking into account the number must be same as well as chlorine. Thus, in order to balance we write:
Zn + 2HCI → ZnCl₂ + H₂
And that is enough. Moreover, we can see that the chemical species at the left side of the equation are the reactants and those at the right side the products, thus we have:
Reactants: Zn and HCI
.
Products: ZnCl₂ and H₂.
Finally, since we can see that the chlorine is at the reactants with hydrogen, but at the end with the zinc, and the initial zinc is alone as well as the yielded hydrogen we can infer this is a substitution reaction.
Best regards.
Answer:
Anser is C Agl
Explanation:
Agl does not dissolve in water.
Answer: 0.4M
Explanation:
This would be much easier if we first analized what was given from the question. This is illustrated below:
C1 = 2M
V1 = 25mL
C2 =?
V2 = 125mL
C1V1 = C2V2
2x25= C2 x 125
Divide both side by 125, we have:
C2 = (2x25) /125
C2 = 0.4M
Therefore, the molarity of potassium bromide formed will be 0.4M
Answer:
It's a Lithium atom
Explanation:
You can count the red particles in the nucleus, they're the protons. This atom have 3 protons. The atom that have 3 protons is the Lithium atom
