What is meant by skeltal type chemical equation?
Answer. The equations in which gaseous are written in atomic form instead of molecular form and equation is not balanced, are called skeletal type equations. They represent gaseous elements formed in an atomic state and the equation is not balanced

Q. What is a chemical equation?
Ans: The representation of chemical reaction by means of symbols of substances in the form of formulae is called a chemical equation.
Q. What is a chemical reaction?
Ans: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.
Q. Are chemical changes and chemical reactions the same?
Q. What is the difference between a physical change and a chemical change?
|Physical Change||Chemical Change|
|When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.||When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.|
|Physical change is a temporary change.||A chemical change is a permanent change.|
|A Physical change affects only physical properties i.e. shape, size, etc.||Chemical change both physical and chemical properties of the substance including its composition|
|Generally, physical changes do not involve the production of energy.||Chemical changes usually involve the production of energy (which can be in the form of heat, light, sound, etc.)|
|In a physical change, no new substance is formed.||A chemical change is always accompanied by one or more new substance(s).|
|Physical change is easily reversible i.e original substance can be recovered.||Chemical changes are irreversible i.e. original substance cannot be recovered.|
