“When we move down a group then there is increase in the size of elements because there occurs increase in atomic mass of the elements.
It means that there occurs increase in number of electrons due to which there will be increase in number of new shells. As a result, size of atom or element increases due to which there is increase in atomic radius of the element.
Therefore, we can conclude that increase in number of electrons makes the atomic radius change down a column of the periodic table.”
It is true because the sun rays hit towards the equator creating warm temperatures near the equator then the poles
The equation which we are required to complete can be completed as follows;
- AgNO3 + KCl ==> KNO3 + AgCl

Most substitution reactions involve displacement of metals and non-metals.
The possibility of a substitution reaction to occur is sometimes dependent on the order of preference of the metals in the activity series.
On this note, In the reaction between AgNO3 and KCl, potassium, K displaces silver, Ag and the products of the reaction are; KNO3 and AgCl

The volume of the steel that is described above is obtained by water displacement method. This means that the volume can be calculated by subtracting the initial volume from the final volume. This will give us an answer of,
volume of steel = 55.5 mL - 45 mL = 10.5 mL
