This is an ideal gas problem. The gas inside the balloon is considered ideal. Ideal gas equation is a function pressure, temperature, amount and volume. Note: amount is constant since the balloon ins closed. Pressure is maintained constant since the walls are flexible. Ideal gas equation is: PV=nRT. Put all constant in one side and variables in one.
P/nR=T/V. To find the answer to the question equate the constants of both situation
T1/V1=T2/V2
(25+273.15)/3=(x+273.15)/2
x=-74.38 degC
Answer:
I'm not all the way sure but I think it is C
Explanation:
The reason is because an ionic bond essentially donates an electron to the other atom participating in the bond. Also, the C-O I think is polar since it is evenly distributed.
Answer:
The answer is supposed to be "Electron cloud" or "Electon".
Answer:
5.45mL
Explanation:
Using Boyle's law equation:
P1V1 = P2V2
Where; P1 = initial pressure
P2 = final pressure
V1 = initial volume
V2 = final volume
According to this question, P1 = 1.2atm, V1 = 25mL, P2 = 5.5atm, V2 = ?
1.2 × 25 = 5.5 × V2
30 = 5.5V2
V2 = 30/5.5
V2 = 5.45mL
Therefore, 5.45 mL sample of F2 gas will occupy a syringe at 5.5atm.
