Explanation:
Hello!
In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:
As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:
Thus, by plugging in the data, we obtain:
Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:
Best regards!
Answer:

Answer:
B. The particles rarely touch each other.
Explanation:
The particles of gases are far apart, so they rarely touch each other. The particles of liquids can slide past each other, and the particles of solids are locked in place next to each other.
In all three states of matter, the particles
- Have a definite volume
- Are in constant motion
- Have kinetic energy
Answer:
a) W = 820J, Q = 3314J =
b) For Path A ; ∆U= -2494J, ∆S = -8.85J/K
For Path B ; ∆U = -2494J, ∆S = -8.85J/K
Explanation:
The step by step and mathematical application is as shown in the attached files.
Answer:
Drinking water can be produced from waste water and from lakes but the difference is in the difficulty of producing water which we can consume.
Drinking water should be clean and toxic free so that if does not affect the human body. Waste water carry more toxic matter in comparison to lake water that's why, producing drinking water from waste water takes more time, expensive and difficult.
So, producing drinking water from waste water is more difficult as it require the removal of more toxic matter than water in lakes.
