Answer:
If periodic table is not color coded then we should look at the group to find elements which have similar chemical properties.
For example: Elements of group 1 forms basic oxides
And elements in group has equal number of valence electrons.
Like elements of group 1 are: lithium, sodium and potassium.

Answer:
B- 65km
C- 2.8km/h
D- average speed
Answer: 20.2 m/s
Explanation:
From the question above, we have the following data;
M1 = 800kg
M2 = 1200kg
V1 = 13m/s
V2 = 25m/s
U (common velocity) =?
M1V1 + M2V2 = (M1 + M2). U
(800*13) + (1200*25) = (800+1200) * U
10400 + 30000 = 2000u
40400 = 2000u
U = 40400 / 2000
U = 20.2 m/s
