Question

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

Answer 1

Explanation :

(1) Sodium hydroxide and calcium bromide

The balanced chemical reaction will be,

$2NaOH+CaBr_2\rightarrow Ca(OH)_2+2NaBr$

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,

$2MgO\rightarrow 2Mg+O_2$

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,

$2Al+3Fe(NO_3)_2(aq)\rightarrow 2Al(NO_3)_3+3Fe$

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,

$2Na+Cl_2\rightarrow 2NaCl$

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