I think, by convention, most would consider the solvent as the major component and the others as solutes. Actually, however, it dosesn't matter.
I just read that when one liquid is dissolved in another, the minor component is usually considered the solute and the major component is the solvent. Now if you mix 3 liquid solvents(acetone, water and alcohol, would the solvents be all 3 or the ones with the most amount? eg. 50mL of acetone vs. 10mL of alcohol and 5mL of water?
I still need help whether the majority solvent is based on the one that has the most mL in the mixture.
what gas is formed when hydrochloric acid and mossy zinc are combined
You may use volume to determine the major component OR you may look up the densities and consider mass of each. It depends somewhat upon what you want to do with it. If this sounds confusing, I would go with volume.
hydrogen gas
When determining the major component in a mixture of solvents, you can use either volume or mass to make the determination. If you choose to use volume, you would compare the volumes of each solvent present. In your example, if you have 50 mL of acetone, 10 mL of alcohol, and 5 mL of water, then acetone would be considered the major solvent because it has the highest volume.
Alternatively, you can consider the densities of each solvent and calculate the mass of each component. The one with the highest mass would be considered the major solvent. However, in this case, you need accurate density values for each solvent and you may need to convert the volumes to masses to make the comparison.
Now, regarding the gas formed when hydrochloric acid and mossy zinc are combined, it is hydrogen gas. The reaction between hydrochloric acid and zinc produces hydrogen gas according to the chemical equation:
Zn (s) + 2HCl (aq) → ZnCl2 (aq) + H2 (g)
So, when you combine hydrochloric acid and mossy zinc, hydrogen gas is released.
