Given the following reactants, determine the type of reaction that will take place, predict the products ,and produce a balanced chemical equation
sodium hydroxide and calcium bromide
magnesium oxide
aluminum and iron (ii) nitrate
sodium and chlorine

Explanation :

(1) Sodium hydroxide and calcium bromide

The balanced chemical reaction will be,

This reaction is a double displacement reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

(2) Magnesium oxide

The balanced chemical reaction will be,

This reaction is a decomposition reaction in which a larger reactant molecule decomposes into two or more smaller product molecules.

(3) Aluminum and iron(II)nitrate

The balanced chemical reaction will be,

This reaction is a single displacement reaction in which the most reactive element displaces the least reactive element.

(4) Sodium and Chlorine

The balanced chemical reaction will be,

This reaction is a combination reaction in which the two or more reactant combine to form a new product.

because it does not have the potential to be entirely used up

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
