Answers
Answer:
1) Hydrogen
2) chlorination is the process of adding chlorine or chlorine compounds.
3) pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per.
5) the smallest unit into which a substance can be divided without changing its chemical nature.
4) Kinetic energy.
6)Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
7) Components of soil: The four major components of soil are shown: inorganic minerals, organic matter, water, and air. The amount of each of the four major components of soil depends on the quantity of vegetation, soil compaction, and water present in the soil.
8) physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
9) The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.
