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
i. The new concentration is 0.116 M
ii. The new concentration is 0.029 M
<h3>What is the concentration of the original hydrochloric acid acid?</h3>
The concentration of the original or stock hydrochloric acid is calculated as follows:
- Molarity = Percentage concentration * Density * 1000/Molar mass * 100
Molarity of stock HCl = 36 * 1.18* 1000 /36.5 * 100
Molarity of stock HCl = 11.6 mol/dm
i. Using the dilution formula: M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 11.6 * 10/1000
M₂ = 0.116 M
The new concentration = 0.116 M
ii. Using M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 0.116 * 5/20
M₂ = 0.029 M
The new concentration = 0.029 M
In conclusion, the new concentrations are found using the dilution formula.

Explanation:
Given a food with a relative humidity of 81%, what is the water activity of that food?
The water activity of a food can be determined by using the formula:
water activity=relative humidity of food / 100
They can probably form 3 of them
Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.
