Answer:
The number of moles of CO2 is 0,54
Explanation:
We use the formula PV=nRT. The conditions of STP are 1 atm of pressure and 273 K of temperature.
PV=nRT n=PV/RT
n=1 atm x 12 L/0,082 l atm/K mol x 273K
n=0,536049316 moles
Answer:
helium
Explanation:
it has 8 valence electrons which fills its outer energy level making it have a stable arrangement of electrons hence least reactive
Answer:
isn't this like solid liquid and gas
