Answer:
Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in meager amounts.
In this case, we can say, The solvent is the water.
A solute is an acetic acid.
The solvent is the dissolving medium in a solution while solute has dissolved particles in a solution.
Example, sugar water. Sugar dissolves in water, so sugar is the solute whereby water is the solvent.
We can say vinegar is acetic acid in water.
Answer:
The entropy will be 0
Explanation:
Because of the third principle of thermodynamics, the entropy of a pure substance (such as SiC59), with finite density (we have 1 mol in a finite volume), at 0 K is equal to 0.
So, it really dosen't mather the Si atom, if you are analizing it at the absolute zero (0 K).
The answer is ethyl methyl ketone.
Answer:
D
Explanation:
Seeing the Lewis formula for each of the molecules, we can attempt to write the condensed structural formula for each.
What we notice is that while there are purely single bonds between the carbon atoms in the first molecule, there is a double bond in the second molecule and a triple bond in the third
What we can deduce from this is that these are alkanes , alkenes and alkynes
The alkynes have the strongest of the three bonds and thus they have the strongest bonds in the mix
Since molecule 3 is an alkyne, then we can say that it has the strongest of the bonds
