M=260 g
M=414.215 g/mol
n=m/M
n=260 g / 414.215 g/mol = 0.6277 mol

Answer:
The temperature of the gas after it is filled is 596 K
Explanation:
According to Gay-Lussac law, the pressure of a gas mass is directly proportional to temperature to a constant volume. That means than if pressure rise, the temperature too. We can assume then the volume is constant because the tank is isolated. The tank will be full when pressure will be in equilibrium, that means when pressure will be 1 atm because it is environment pressure. Using the following equation:
P1 /T1 = P2 /T2 and replacing, T2 = P2 *T1 / P1 = 1 atm * 298K / 0.5 atm = 596 K.
I hope my answer helps you
Answer:
I'm not the best at chemistry but from what I remember you need to balance the equation and you need the arrows. It wants you to use double displacement and so thats the definition im assuming.
Explanation:
An example would be
Na2SO4 + SrCl2 --> 2 NaCl + SrSO4
This is a balanced equation.

This link will help you balance an equation.
Hopefully this helps I appologize if it doesn't.
