Answer:
heat?
Explanation:
the sun warms the popsicle, therefore melting th popsicle.

The solution contains 39.4% of LiF. Assume that the solution is 100ml. The molar mass of LiF is 25.939, the amount of LiF in mole would be: 100ml * 1g/ml * 39.4%/ 25.939g/mol= 1.52 mol LiF
Then the mass of the water would be: 100gram- 39.4g= 60.6g
If the molar mass of water is 18.015 the mole of the water would be: 60.6g/ 18.015g/mol= 3.36 mol
.
The mole fraction would be:1.52 mol/ 1.52+3.36= 0.339
In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins<span>, glucose and charged particles called ions cannot pass through the selectively permeable membrane.</span>
Answer:
the "d" option
Explanation:
Cómo se pronuncia
To calculate the flow I need the volume and time to comply with the formula:
S = V / t
V = volume
t = time
In this problem I have volume and density as data.
There is no way to calculate the time so the correct answer is the "d" option
