Answer:
[K₂CrO₄] → 8.1×10⁻⁵ M
Explanation:
First of all, you may know that if you dilute, molarity must decrease.
In the first solution we need to calculate the mmoles:
M = mmol/mL
mL . M = mmol
0.0027 mmol/mL . 3mL = 0.0081 mmoles
These mmoles of potassium chromate are in 3 mL but, it stays in 100 mL too.
New molarity is:
0.0081 mmoles / 100mL = 8.1×10⁻⁵ M
Answer:
Heat flux = 13.92 W/m2
Rate of heat transfer throug the 3m x 3m sheet = 125.28 W
The thermal resistance of the 3x3m sheet is 0.0958 K/W
Explanation:
The rate of heat transfer through a 3m x 3m sheet of insulation can be calculated as:
The heat flux can be defined as the amount of heat flow by unit of area.
Using the previous calculation, we can estimate the heat flux:
It can also be calculated as:
The thermal resistance can be expressed as
For the 3m x 3m sheet, the thermal resistance is
Glass 1 Freshwater
The egg went directly to the base of the glass. Consequently it has sunk and did not drift

Glass 2
Water with 2 teaspoons of salt
A similar outcome for glass 2 as container 1 when egg was set into the container it sank to the base.

Glass 3
Water with 3 teaspoons of salt
In reference to glass 1 and 2 the egg sank to the base for a third time.

Glass 4
Water with 4 teaspoons of salt
The egg remained gliding to where a little bit of the egg was standing out on the top, and when pushed down the egg returned up.
