Answer:
The concentration is 4.16 grams per liter, we call the solution saturated.
Explanation:
Step 1: Data given
The solubility of calcium chromate in water is 4.16 grams per liter.
Saturated Solution : A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.
Unsaturated Solution: A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.
Supersaturated Solution: A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate.
Step 2:
If the calcium chromate solution has a concentration of 4.16 grams per liter.
If the concentration is less than 4.16 grams per liter, we call it unsaturated.
If the concentration is more than 4.16 grams per liter, we call it supersaturated.
The concentration is 4.16 grams per liter, we call the solution saturated.

Determine the specific heat of a material if a 35 g sample absorbed 96 J as it was heated from 293 K to 313 K.
Answer : The specific heat of a material is, 0.137 J/g.K
Explanation :
Formula used to calculate the specific heat of a material is:
where,
q = heat absorbed = 96 J
m = mass of sample = 35 g
c = specific heat capacity of material = ?
= initial temperature = 293 K
= final temperature = 313 K
Now put all the given values in the above formula, we get:
Therefore, the specific heat of a material is, 0.137 J/g.K
The dye molecules move in a directed way from high to low concentration
Explanation:
The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion:
- diffusion is the movement of molecules of a substance from one position to another.
- diffusion occurs from a region of high concentration to that of a low concentration.
- the dye in the water solution causes an increase in concentration of an area where it is dropped.
- this causes the particles to spread outward in the solution.
- a concentration gradient is set up between the two parts of the solution.
- this gradient facilitates the movement of the dye particles.
