Acids dissolve in water to produce a solution that reacts with metals to produce H2 gas.
Acids dissolve in water to produce a solution that cannot conduct electricity.
Acids dissolve in water to produce a solution that is slippery.
An unsaturated solution is a chemical solution in which the solute concentration is lower than its equilibrium solubility.
Answer:
Units of energy!
Explanation:
E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
Red #40 is soluble in water while zinc oxide is not.
So the easiest way to separate them is as follows:
1- add water to the mixture until red #40 is dissolved in the water
2- filter to separate the zinc oxide
4- heat the solution of red #40 and water until water evaporates and red#40 remains.
