This can be explained by the periodic trend that atomic size decreases from left to right in a given period. This is due to the effective nuclear charge increase, or how much more the nucleus pulls in on the electrons. Therefore Sodium (Na) has the largest atomic radius.
Answer:
Ksp of PbSO4 is 2.5 *10^-8
Explanation:
Given -
Solubility of PbSO4 = 0.048g/Liter
[Pb+2] * [SO42-] = mass/molecular weight of PbSO4
[Pb+2] * [SO42-] = 0.048g/Liter/303.3g/mol = 0.000158 M
Concentration of PbSO4 = moles/volume = 0.000158 M/1L = 0.000158 M
Ksp = [Pb+2] * [SO42-]
ksp = 0.000158 * 0.000158 = 2.5 *10^-8

The elements in this list are:
Silver, hydrogen, carbon, nitrogen, gold, magnesium, nickel, mercury.
Explanation:
Elements are chemical substances that can be found on the periodic table.
Explanation:
Air borne pollutants are usually very light particles that are usually carried in the air in the atmosphere. Some of these pollutants can be carried far away and some are found close to their sources.
Some of the factors are:
- Wind pressure: if wind pressure is low, pollutants will not be carried far away. In this situation, the particles will be blown and carried over a short distance from their sources. When wind pressure is very high, pollutants will be carried extensively into farther areas.
- Pollutants can be trapped in snow. In a snowy area, when pollutants reach sky high and enters condensed water in the atmosphere, they can become super cooled into ice and fall back within the same area where they are formed.
- Rain water can also cause pollutants to be dispersed within a short area. Pollutants can mix with rain water and carrier back to the area where they were originally formed.
