The answer is false. Hope this helps
The temperature in kelvin does 60.5 liters of sulfur dioxide occupy if there are 2.5 mole at 0.75 atm is 221.07 kelvin
Explanation
This is calculated using ideal gas equation, that is PV=nRT
where, P(pressure) = 0.75 atm
V(volume) = 60.5 L
n(moles) = 2.5 mole
R( gas constant) = 0.0821 L.atm/mol.k
T(temperature =?
by making T the subject of the formula
T is therefore =Pv/nR
T= (0.75 atm x 60.5 L) / ( 2.5 molex 0.0821 L.atm/mol.K) = 221.07 kelvins
Metalloids show both metal and non metal properties
To find the mass in grams of Selenium, you use the moles you have and multiply it by the molar mass.
5489 Moles Se * (79g Se / 1mole Se) =433631g of Se
Answer:
equation number 3 is balanced.
hope it helps ☺️!
