Answer:
Ratio of Vrms of argon to Vrms of hydrogen = 0.316 : 1
Explanation:
The root-mean-square speed measures the average speed of particles in a gas, and is given by the following formula:
Vrms = 
where R is molar gas constant = 8.3145 J/K.mol, T is temperature in kelvin, M is molar mass of gas in Kg/mol
For argon, M = 40/1000 Kg/mol = 0.04 Kg/mol, T = 4T , R = R
Vrms = √(3 * R *4T)/0.04 = √300RT
For hydrogen; M = 1/1000 Kg/mol = 0.001 Kg/mol, T = T, R = R
Vrms = √(3 * R *T)/0.001 = √3000RT
Ratio of Vrms of argon to that of hydrogen = √300RT / √3000RT = 0.316
Ratio of Vrms of argon to that of hydrogen = 0.316 : 1
Answer:
Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature. This is because Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life.
Explanation:
Ahh there isn’t a group 29 on the periodic table, but do you mean which element had the atomic number 29 because that would be Copper (Cu).
Hope this helps :)
