Acommon idea prevails that when “Language of Chemistry” constitutes a part of Inorganic Chemistry textbooks, what is the justification of bringing out a seperate . ISBN: Binding: Paperback. Language: English. Imprint: S. Chand Publishing. Series: Books for Various Competitive Examinations. We recommend that you review your book three times, with each time focusing on a different To print this proof we recommend that you scale the PDF to fit the size In everyday language a theory means a hunch or speculation. Not so in.
It will lose its 2 outer electrons to complete its octet and acquire stable electronic configuration. Oxygen has 6 electrons in its outer shell. It will gain 2 electrons to complete its octet and acquire stable electronic configuration. Atoms of elements like iron, copper sometimes lose more electrons than are present in its outermost shell valence shell i.
A radical is an atom or group of atoms with valency and charge. The chemical formula for: Reactants Products [left side] [right side].

Write the correct formulas for all the reactants and products in the reaction. Count the number of atoms of each element in the reactants and products.
Balance the elements one at a time by using coefficients. It is best to begin with an element other than hydrogen or oxygen. Check each atom to be sure that the equation is balanced. Finally, make sure that all the coefficients are in the lowest possible ratio. Subscripts should never be changed when trying to balance a chemical equation. Balancing of a chemical equations-An example.

Sahib Matharu. It does not inform about the rate at which a reaction proceeds.
It does not inform about the heat changes during the reaction i. It does not inform about the conditions such as temperature, pressure, catalyst etc. It does not inform about the nature of the reaction i. Question 8.
What are the ways by which a chemical equation can be made more informative? Answer: A chemical equation can give more informations in the following ways: The physical state of the reactants and products can be indicated by putting s for solid, l for liquid, g for gas and aq for aqueous state. Evolution or absorption of heat during the reaction can be denoted by adding or subtracting a heat term on the product side.

Concentration of reactants and products are indicated by adding word dil for dilute and cone for concentrated before their formulae. Question 9. State the law of conservation of mass. Answer: Law of conservation of mass: It states that mass can neither be created nor destroyed in a chemical reaction. During any change physical or chemical , matter is neither created nor destroyed.Teaching science as a language: A content-first approach to science teaching.
