Answer: B) The identity of the solvent
Explanation:
Basically, the solvent is the liquid in which a solute is dissolved in. But the solute is the material to be dissolved.
Now in this case, the solute in the first solution is glucose and the solute in the second solution is an unidentified covalent solid material.
This means that:
• the identity of the solute cannot be identical in each solutions, which also means that the freezing points and densities of the solutions cannot be identical too.
• the only thing that is sure to be identical in the solution is the identity of the solvent.
Answer:cotton
Explanation: cotton absorbs sweat and heat . the sweat is evaporated and thus it cools the body . so cotton is best for summer
The name of that compound would be ammonium phosphate.
A) ppm or ppb
Explanation:
To express the concentration of the lead sample in the water, the best way is to use ppm or ppb.
ppm = parts per million
ppb = parts per billion
- ppm and ppb are used to make sense of small concentration values.
- It is the best way of expressing the small amount of solute that is dissolved in a large amount of solvent.
- Other percentage units will not make sense for this expression as they would be too small to make sense of.
The ppm or ppb helps to simply express dilute concentration.
