Answer:
P₂ = 1102 Kpa
Explanation:
Given data:
Initial pressure = 1000.0 Kpa
Initial temperature = 20.0°C
Final temperature = 50.0°C
Final pressure = ?
Solution:
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 50.0°C (50+273 = 323 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1000 Kpa / 293 K = P₂/323 K
P₂ = 1000 Kpa × 323 K / 293 K
P₂ = 323000 Kpa. K /293 K
P₂ = 1102 Kpa

Explanation:
The ionic radius of metal M decreases as the charge on the metal M increases. The ionic radius is generally defined as the distance between the nucleus and the outermost electron of the ion. Hence, ionic radius becomes much lesser as the magnitude of the positive charge increases.
It is obvious from the various formulae of metal chlorides in the question that the metal forms cations M^2+, M^3+ and M^4+ respectively. The order of decreasing ionic radius of the compounds is;
MX2 > MX3 > MX4
7.22 moles of C2H6. Since there are 2 carbon atoms per C2H6, we must multiply the number of moles of C2H6 by 2 to get the number of moles of Carbon which is 14.4 or 14 if using two sig figs.
