Answer:
The value is 
Explanation:
From the question we are told that
The initial volume of the fluorocarbon gas is 
The final volume of the fluorocarbon gas is
The initial temperature of the fluorocarbon gas is 
The final temperature of the fluorocarbon gas is 
The initial pressure is 
The final pressure is 
Generally the equation for adiabatically reversible expansion is mathematically represented as
![T_2 = T_1 * [ \frac{V_1}{V_2} ]^{\frac{R}{C_v} }](https://tex.z-dn.net/?f=T_2%20%3D%20%20T_1%20%20%2A%20%5B%20%5Cfrac%7BV_1%7D%7BV_2%7D%20%5D%5E%7B%5Cfrac%7BR%7D%7BC_v%7D%20%7D)
Here R is the ideal gas constant with the value
So
![248.44 = 298.15 * [ \frac{V}{2V} ]^{\frac{8.314}{C_v} }](https://tex.z-dn.net/?f=248.44%20%3D%20%20%20298.15%20%20%2A%20%5B%20%5Cfrac%7BV%7D%7B2V%7D%20%5D%5E%7B%5Cfrac%7B8.314%7D%7BC_v%7D%20%7D)
=> 
Generally adiabatic reversible expansion can also be mathematically expressed as
=>![[ 81.840 *10^3] [2V]^{\gamma} = [202.94 *10^3] V^{\gamma}](https://tex.z-dn.net/?f=%20%5B%2081.840%20%2A10%5E3%5D%20%5B2V%5D%5E%7B%5Cgamma%7D%20%3D%20%5B202.94%20%2A10%5E3%5D%20V%5E%7B%5Cgamma%7D)
=> 
=> 
So
=>
The student originally has 252 grams of water in this experiment.
LAW OF CONSERVATION OF MASS:
- The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another.
- This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s).
- According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen.
- Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water.
- Therefore, 224g of oxygen + 28g of hydrogen = 252g of water.

Answer: 1.09 g
Explanation:
If we use the approximation that 1 mole is 22.4 L, then setting up a proportion,
- 1/22.4 = x/0.345 (x is the number of moles in the sample)
- x = 0.0154 mol
Since the mass of a mole of chlroine is about 70.9 g/mol, (0.0154)(70.9) = 1.09 g (to 3 s.f.)
Answer:
True
Explanation:
When ice is heated, the ice gains heat.
This heat gained by the ice is both used to break the intermolecular forces in ice to form water, as well as to raise the temperature of the water to it's final temperature.
