Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or how much product will be formed in a reaction.
I'm pretty sure it's D. Compounds
Salt water is an example of a solution, and a solution is a type of mixture, so by multiple choice logic none can be the right answer! Seriously though - mixture are combinations of two compounds that are physically combined but do not undergo a chemical reaction with one another to produce a new compound. For instance, when you dissolve salt in water, you don't produce any new products, and you can boil away the water to leave only the salt (a physical method of separation). You cannot separate a compound by physical means because by definition this would be a chemical reaction as you're breaking bonds.
It forms Carbon monoxide.
CO2 +O2⇒ CO
(Sorry not balanced)
Because of the ammount of water and the boling point of the Ganga River has changed due to the mixtures of different kind of chemicals and acids
