Answer:
It has direction and size.
Explanation:
All physical quantities are generally grouped into two;
i) Vector quantities
ii) Scalar quantities
Vector quantities are those quantities that has both magnitude (size) and direction.
Scalar quantities are those quantities that has magnitude (size) and no direction.
Velocity is a vector quantity because it has direction and size.
Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be
FRANCIUM, which is at the base of Group One.
Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
Answer:
Its C

Got 100% on test edge 2020
Answer:
You can
Explanation:
The concentration doesn't change when its equals out.
1) The metal which reduces the other compound is the one higher in the reactivity. So in this case it is
.
2) The substance which brings about reduction while itself getting oxidised (that is losing electrons) is called a reducing agent. Here, $\mathrm{Zn}$ is the reducing agent and reduces Cobalt Oxide to Cobalt while itself getting oxidised to Zinc oxide.
