They separate because of different densities.
The answer to your question would be C. Also you put two "B"'s XD
In photograph a, a coil of zinc metal is in a solution of sulfuric acid. In photograph b, a yellow solution of sodium chromate is being added to a colorless solution of silver nitrate. What clues in the photographs indicate that a chemical change is probably occurring.
In photograph a, chemical change is occuring as when a coil of zinc metal is in a solution of sulfuric acid, then the solution starts bubbling, that indicates a chemical change.
In photograph b, a yellow solution of sodium chromate is being added to a colorless solution of silver nitrate, that changes the color of the solution to red , that indicates a chemical change.
A hypothetical gas that perfectly fits all the
assumptions of the kinetic- molecular theory is Ideal gas.
(they actually don't exist)
Answer:
The obtained result indicates that the hydrogen atom is not equal on both sides. Thus the reaction is not balanced.
