How Acid rain is formed equations? Formation of acid rain:Sulphur dioxide accounts for most of the acid rain problems. (a) When sulphur dioxide dissolves in water, sulphurous acid is formed. SO2(g) + H2O(l) → H2SO3(aq) (b) Sulphur dioxide can react with oxygen and water to form sulphuric acid. 2SO2(g) + O2(g) + 2H2O(I) → 2H2SO4(aq) Acid rain occurs when the pH of … [Read more...] about How Acid rain is formed equations?

What are the properties of a pure metal? Pure Metals:Typical pure metals have the following physical properties:Ductile- can be drawn into fine wire Malleable- can be beaten into thin sheets without cracking Lustrous- becomes shiny when polished High density High melting and boiling points Good conductor of heat and electricityThese … [Read more...] about What are the properties of a pure metal?
What are Metallic and Nonmetallic Properties
What are Metallic and Nonmetallic Properties Metals generally show less electronegative character. In compounds, they generally show a tendency to remain as positive ions. This property is often termed as electropositive character. Metals are electropositive elements. Non metals are generally more electronegative due to their smaller atomic radii. Let … [Read more...] about What are Metallic and Nonmetallic Properties
Which acid is used for coagulating rubber from latex?
Which acid is used for coagulating rubber from latex?Coagulation process of latex:The milky fluid obtained from tapped rubber trees is called latex. It consists of an aqueous suspension of colloidal rubber particles. Each rubber particle is made up of rubber polymers covered by a layer of protein membrane. Negative charges are found on the surface of the … [Read more...] about Which acid is used for coagulating rubber from latex?
What is meant by the calorific value of a fuel?
What is meant by the calorific value of a fuel?Fuels are substances that can normally burn readily in air or oxygen to produce large quantity of heat. Examples of some common fuels are petroleum, natural gas and coal. These are called fossil fuels. Different types of fuels have different heats of combustion. Heat of combustion is expressed in kilojoules per … [Read more...] about What is meant by the calorific value of a fuel?
