Single Replacement & Decomposition

<h3>Further explanation</h3>

Given

Two chemical reactions

1. Cl2 + 2NaBr ⇒2NaCl + Br2

2. 2NaCl ⇒2Na + Cl2

Required

Type of reaction

Solution

Equation 1 : A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

General formula :

A + BC ⇒ AC + B

Equation 2 : the decomposition reaction of a compound into its constituent elements or compounds

General formula :

AB ⇒ A + B

How do you sort bonds by polarity

zzz [600]

Your question isn't quite clear, but if you're wondering if a chemical is polar or non-polar, you simply draw a VSEPR sketch and draw arrows where the bonds are. Only draw arrows between atoms, NOT between an atom and a lone pair of electrons. The arrow should point to the most electronegative atom (you should be given an electronegativity scale). Afterwards, you add up the arrows as vectors, and look at the sum of the vectors. If the sum is zero (CH4 is a good example), the chemical is non-polar. If the sum is a vector, the chemical is polar (H2O, or water, is polar).

2.) Average atomic mass =Σ (abundance x molar mass) /100 = (12.64 x 302.04 + 18.23 x 304.12 + 69.13 x 305.03) /100 =304.486 u(Dalton) . This is avg atomic mass.
