27 it would be neutral if it had 24 electrons and 24 protons but because it is +3 that means it had 3 more protons than electrons so the answer would be 24+3
Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.
Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.
Answer:
It is a chemical change
Explanation:
the reason is because the will not be able to materialize back into it's original form.
Answer:
5.42 mL needed to be added and 1.04 M of dilute solution
Explanation:
For both cases, you need to use the expression:
M1*V1 = M2*V2
where M and V are concentration and volume.
For the 1st question, we have both concentrations, but we do not have both volume so:
3 * V1 = 0.325 * 50
V1 = 0.325 * 50 / 3
V1 = 5.42 mL need to be added.
For question 2:
Same as above, with the difference that we need to calculate concentration so:
12 * 4.35 = M2 * 50
M2 = 12 * 4.35 / 50
M2 = 1.04 M is the concentration of the diluted solution
