The alloy has a density of 21.186g/cc. So for a kilogram or 1000 grams/21.186 g/cc= 45.7 cc. So the answer is 45.7 cc of the allow to make up a kilogram which shows that the density of the allow can be used to calculate the volume of a larger mass ie the kilogram.
Soap is polar because it is not symmetrical in molecularly, this is because it must react with whats on your hand to fully clean it , dish soap is nonpolar/polar in order to combat grease which is also nonpolar, so nonpolar cleans nonpolar and polar cleans polar
Answer:
Density dependent factors include disease, competition, and predation. Density dependant factors can have either a positive or a negative correlation to population size

Answer:
The answer is in the explanation.
Explanation:
A buffer is defined as the aqueous mixture of a weak acid and its conjugate base or vice versa. Buffers are able to avoid the pH change of a solution when strong acid or bases are added (As NaOH).
Based on the experiment, it is possible that the solution Z was a buffer and Y another kind of solution. For this reson, pH of the solution Y changes much more than the pH of solution Z changes despite the amount of NaOH added is the same in both solutions.
