In a solution that is 90% ethyl alcohol and 10% water, the solute is 10 g and the solvent is 90 g.
given that :
The solute in the solution by mass percent = 10 %
mass percent = ( mass of solute / mass of solution ) × 100%
mass of solute in the solution is = 10 g
The solvent present in solution by mass percent = 90 %
the mass of solvent in the solution is is 90 g
Thus, In a solution that is 90% ethyl alcohol and 10% water, the solute is 10 g and the solvent is 90 g.

Answer:
A
Explanation:
When it comes to gases, volume and pressure have an indirect relationship, when one increases the other decreases and vice versa.
The correct answer is blue
Carbon monoxide, nitrogen oxides, and hydrocarbons
Carbon monoxide, CO, is a <em>poisonous gas</em>.
Nitrogen oxides (e.g. NO and NO_2) cause <em>smog and acid rain</em>.
Hydrocarbons (general formula C_xH_y) cause <em>smog</em>.
Answer:
Burning of fossil fuels releases a lot of pollutants such as sulphur dioxide and nitrogen dioxide into the atmosphere, and reacts with the water in the atmosphere to form sulphuric acid or nitric acid. Hence, acid rain is formed as that acid comes down from the atmosphere along with the rain.
