Answer:
True
Explanation:
Diffusion is the movement of the particles of a substances from a region of higher concentration to a region of lower concentration.
Diffusion occurs in response to a concentration gradient.
In this case, the dye is at a higher concentration at the middle of the shallow dish of water. Diffusion causes the dye to spread out gradually thereby causing the red cloud to grow larger with time.

<u>Answer:</u> The solubility of nitrogen gas in the sample is
<u>Explanation:</u>
We are given:
Volume percent of nitrogen gas = 80 %
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= partial pressure of nitrogen gas = 1.0 atm
Putting values in above equation, we get:
Solubility of nitrogen gas in the sample =
Hence, the solubility of nitrogen gas in the sample is
