Question

1) What is radicals?
2)What is a balanced chemical equation?
3) How to find formulae of elements to compounds?

Answer 1

1) $\large\underline\mathtt{Radical:}$

➡An atom or a group of atoms carrying either positive or negative charge

➡radical is an atom, molecule, or ion that has an unpaired valence electron.

2)$\large\underline\mathtt{Balanced\: Chemical\:Equation:}$

➡A balanced equation is one, in which the number of atoms of the reactants and the number of atoms of the products are equal.

➡ Chemical equations are balanced to follow the law of conservation of mass, which states that in any chemical reaction the mass of products and reactants are always equal.

3) $\large\underline\mathtt{Finding\: formulae\: of\:elements\: to \:compounds:}$

Chemical formulas is a way to represent the number and type of atoms in a compound!

➡Write the symbols with positive charge valency & write the valency of each atom on the top of its symbol.

➡Divide the valency number by their highest common factor.

➡Interchange the valency of the radicle.

➡Finally,write the interchanged valency number to the lower right of the radicle.
