Answer:The density of ammonia (
) at 273 K and 1.00 atm is 0.75 g/L.
Explanation:
Temperature of the gas = T = 273 k
Pressure exerted by the gas,P = 1.00 atm
Volume occupied by the gas = V
Number of moles of gas = n
PV=nRT (Ideal gas equation)
Density of the gas:
The density of ammonia () at 273 K and 1.00 atm is 0.75 g/L.
Answer:
D.
Explanation:
They both have 1 electron in their valency shell so they will not react.
They are both alkali metals: Lithium and Sodium.
