Because of pollution from factories and other activities that release harmful gases into the air
(H3po4) is colorless, syrup + Potassium Hydroxide(3koh)-> Tripotassium phosphate(k3po4)+Water(3h2o which means it has 3 water molecules)
Answer:
If this is multiple choice it would be: 1. Close in size, and 2. They are about the same distance from the sun.. Hopefully these will help.
Explanation :
Barfoed's test : Monosaccharides and reducing disaccharides can be distinguish by this test. The test solution is prepared by dissolving copper (II) acetate in acetic acid.
The equation for the oxidation of glucose by CuO is:
(1)
(2)
Here, CuO act as a catalyst.
In this reaction, first CuO salt get oxidized to form and then get reduced to back (CuO).
Hence, the equations are written above.
