Nothing it'll just stay the same
Explanation:
Is this a joke?
Answer:
Final pressure = 0.77atm
Explanation:
The concept used to approach this question is the Ideal gas equation
PV = nRT
where P = pressure
V = Volume
n = number of mole or amount of substance
R = ideal gas constant
T = Temperature in Kelvin
- from the parameters given ; mass = 391g
- Temperature = 695 ∘C = 695 + 273 = 968K
- number of moles = mass/molar mass
- molar mass of CO2 = 12 + 2x16 = 44g/mol
- number of moles = 391g/44g/mol = 8.886mol
plugging into the equation to get the final pressure,
- P = nRT/V = 8.886 x 0.0821 x 968 / 0.770
Answer:
D= 5 g/L
Explanation:
M= D x Vm
M is the molar mass = 112g/mol
D is the density
Vm is the molar volume whuch is 22.4L at STP
now substitute;
112 = D x 22.4
D= 112\22.4
D= 5 g/L
Answer:
The change during the burning of a match stick is a irreversible chemical change while the change when a liquid starts boiling is reversible chemical change.
