A pair of electrons(2 electrons) are shared in a single bond.
Hope this helps you.
Correct answer is fossil
Combustion of fossil fuels is the major cause of air pollution.
5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
The root mean square speed of a gas is calculated through the equation,
Vrms = sqrt (3RT/M)
where:
Vrms = root mean square velocity/speed
R = universal gas constant
T = temperature
M = molar mass of the gas
Fluorine gas is a diatomic particle, F2, with a molar mass equal to 37.997 g/mol. Substituting the known values to the equation,
Vrms = sqrt (3)(0.0821 L.atm/mol.K)(425 + 273.15)) / 37.997 g/mol))
Vrms = sqrt ((3)(0.0821 L atm)(101325 kg/ms²/1 atm))(698.15 K) (1 m³/1000L)/ (37.997 g)(1 kg/1000g))
Vrms = 25.63 m/s
ANSWER: 25.63 m/s
Answer:
false
Explanation:
The atom model has changed over time because of the discovery of subatomic particles
