<em>It is a lava type.....</em>
Answer:
1. Evaporation
2. Condensation
3. Precipitation
4. Runoff
Explanation:
The water cycle shows how water moves on the earth as it passes through different phases.
Water on land is stored in oceans, rivers and other water bodies. This water coupled with those in plants and animals are turned into vapor through EVAPORATION. Evaporation facilitates the movement of water on the surface into the atmosphere.
In the atmosphere, the vapor condenses on dust particles found up there. The vapors forms a nuclei around the dust particles and water condenses at the saturated vapor pressure. This forms cloud.
As the water collects more and more, gravity forces the water to fall in form of PRECIPITATION. The precipitation can be in form of snow or rainfall.
When precipitation occurs, they move on the surface as SURFACE RUNOFFS. Some of the runoff goes back into oceans and rivers. Others infiltrates into the ground and collects in the ground water pool under the subsurface. Subsurface water can also get into into other water bodies when the water table coincides with the steam level.
The water in these bodies can then go into the cycle again. The sun is the source of energy for this process.
Because it is a monoprotic acid equivalent mass = molar mass
Answer:
2s² 2p⁵
There are seven valance electrons in fluorine.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other.
Properties of fluorine:
1. it is yellow in color.
2. it is flammable gas.
3. it is highly corrosive.
4. fluorine has pungent smell.
5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.
Electronic configuration of fluorine:
F₉ = 1s² 2s² 2p⁵
Valance electrons in fluorine are 2s² 2p⁵.
Valance Orbital configuration:
2s² 2p⁵
There are seven valance electrons in fluorine.
