Carbon dioxide can’t exist in three states; Gas, Liquid & Solid. At normal temperatures and pressures, CO2 is colorless with a slightly pungent odor at high concentrations. If compressed and cooled to proper temperature the gas liquifies. Solid CO2, (dry ice) sublimates back to the natural gaseous state.
Answer: The pressure will be 18.05 atm.
Explanation: Expression for ideal gas equation is :

where,
P = Pressure of the gas = ? atm
V = Volume of the gas = 0.333L
n = Number of moles of gas = 0.250 moles
R = Universal gas constant = 
T = temperature of the gas = 20°C = (273 + 20)K = 293K
Putting values in above equation, we get:

P = 18.05 atm
zero because its not going anywhere its stationary
hope this helped ^_^
Answer:
no of neutron = atomic mass - atomic number
Explanation:
here
atomic mass = 64
atomic number = 30
no of neutron = <span>64−30</span>
no of neutron = 34
Is there a graph? I need to see a graph in order to help
