Answer:
Explanation:
Initial pressure, P = 125 kPa
Initial temperature, T = 25.0°C
If new pressure is increased to P' = 150.0 kPa
We need to find new temperature. According to Gay-Lussac's law,
P ∝ T
or
So, the new temperature will be .
The parent isotope percent will change from 100% to 50% to 25% to 12.5% and to 6.25%. So the sample go through four times of half-life. So the sample is 58*4=232 years old.
Na would form a 1+ ion losing its electron to the Cl to make a Cl- ion. Gives the molecule NaCl
- The mass in kilograms is (11971.98 Kg)
- Pounds can be converted to pounds to kilograms by using this conversation (1 pound = 0.454 kilogram)
<em />
- <em>Let X= mass of the object in kilograms</em>
- <em>(1 pound = 0.454 kilogram)</em>
- 26370 pounds = X kilograms
- <em>If we cross multiply, we have </em>
- (0.454 kilogram × 26370 pounds) = X kilograms
X = 11971.98 Kg
- Therefore, mass in kilograms is (11971.98 Kg)

A cone of depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer, this is an actual depression of the water levels. In confined aquifers, the cone of depression is a reduction in the pressure head surrounding the pumped well.
