1. 2KCIO3, -- 2KCI + 302<br> How many moles of O2 will be produced from 2.25 moles of KCIO3?
Scilla [17]

Answer:

3.375moles of O₂

Explanation:

The reaction expression is given as;

                   2KClO₃ → 2KCl + 3O₂

Number of moles of KClO₃  = 2.25moles

Now;

To find the number of moles of O₂ produced we use known number of moles.

So;

                  2 mole of KClO₃ will produce 3 moles of O₂

                 2.25moles of KClO₃ will produce \frac{2.25 x 3}{2}   = 3.375moles of O₂

Which of the following would be classified as an acid to the Arrhenius definition
mixer [17]

Any substance that increases the concentration of H^+ in aqueous solutions is Arrhenius's acid.

<h3>What are Arrhenius acids?</h3>

Arrhenius define acids as substances with the chemical capacities to increase the concentration of hydrogen ion in aqueous solutions.

Thus, substances like HCl, HNO3, HBr, etc. would be considered an acid. This is because they ionize in aqueous solutions as follows:

HCl ---> H^+ + Cl^-

HNO_3 --- > H^+ + NO_3^-

HBr --- > H^+ + Br^-
