The reactant that is finished itself during any chemical reaction is called the limiting reactant. or, The reactant that limits the amount of product is called the limiting reactant or limiting reagent. If there is more than one reactant in a chemical reaction, it is not always possible to supply all the reactants in the … Read more
The amount of dissolved gram molecular mass or mole of a solute in per liter of any solvent at a fixed temperature is known as the molarity of that solution.
The number of electrons lost to form a positive ion or the number of electrons gained to form negative ion by an element while forming a compound is called the oxidation number of that element.
Brine is a high concentration solution of NaCl.
If 1 liter of solution has 0.1 mole solute then it is called decimolar solution. Decimolar solution means the molarity of solution is M/10 or 0.1 M. That is, 0.1 mole of solute is dissolved in 1 L of solution. Since, 1 L=1/1000 m3, therefore it can be said, 0.1 mole of solute is dissolved … Read more
The combination of proton and neutron number in the atom nucleus is called nucleon number.
The chemical reaction which generates heat is called an exothermic reaction.
The important elements of the environment, soil, and water get severely contaminated when pesticides are used excessively. Again, excessive use of pesticides lessens the fertility of the soil and causes pollution. Besides, pesticides pollute water by getting mixed in water and reaching rivers and ponds.
