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.

<h3><u>Answer;</u></h3>
B. Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor.
<h3><u>Explanation</u>;</h3>
- NADH and FADH2 are two important electron carriers in the cellular respiration process.
- NADH is a high-energy electron carrier that is reduced during glycolysis, pyruvate processing, and the citric acid cycle, and which carries electrons to the electron transport system.
- The electron transport chain passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers.
Natural gas is primarily composed of methane (CH4)
Natural gas is a naturally occurring hydrocarbon mixture which is primarily composed of Methane(CH4), but it also contains ethane,propane and heavier hydrocarbon. In addition it contain small amount of nitrogen, carbon dioxide,hydrogen sulfide and traces amount of water.
Answer:
Its kinetic energy
Explanation:The dart is in motion because of the potential energy being stored and turned into kinetic energy, plus since the dart is aerodynamic, it would have more speed for it to hit the dart board.
C. Their components can be separated by physical processes.
