Hello!

A substance that could be found in air, water or soil that is harmful to humans or animals is a Pollutant.

The other substances cannot be found in air, water or soil. Fossil fuels can only be found in soil, smog can only be found in the air, and carbon dioxide can be found in the water or air. 

Pollutants 
are substances that have harmful effects and damage the environment.  Some examples of pollutants are Carbon Monoxide (air), Lead (soil) and Insecticides (water). 

Have a nice day!

Oxygen gas, generated by the reaction 2 KClO 3 ---- 2 KCl + 3 O 2 , is collected over water at 27 C in a 2.00 L vessel at a tota
laila [671]

Answer:

The moles of KClO3 = 0.052 moles

Explanation:

Step 1: Calculate the pressure of oxygen gas

The oxygen has a total pressure (including water vapour) of 760 mmHg

The pressure of Oxygen = (760 - 26) mmHg

                                         = 734 mmHg of water vapor

Step 2: Calculate the no of moles of oxygen

        Using Ideal gas equation

        P V = n R T

       P = pressure of oxygen in N/m2 ( you should convert 734 mmHg to pascal or N/m2) = 97,858.6 N/m2 or pas

       V = 2 litres = 0.002 m3

       R = gas constant = 8.31

       T= 27oC = 300 K

Applying this equation P V = n R T

        97,858.6 x 0.002 = n x 8.31 x 300

        n = 0.0785 mol of Oxygen

From the balanced equation

2 KClO 3 ---- 2 KCl + 3 O 2

3 moles of oxygen is produced from 2 moles KClO3

so 0.0785 mole of oxygen will be produced from x

x = (0.0785 x 2 ) / 3

x = 0.052 moles of KClO3
