Answer:
Root mean squared velocity is different.
Explanation:
Hello!
In this case, since we have a mixture of oxygen and nitrogen at STP, which is defined as a condition whereas T = 298 K and P = 1 atm, we can infer that these gases have the same temperature, pressure, volume and moles but a different root mean squared velocity according to the following formula:

Since they both have a different molar mass (MM), nitrogen (28.02 g/mol) and oxygen (32.02 g/mol), thus we infer that nitrogen would have a higher root mean squared velocity as its molar mass is less than that of oxygen.
Best regards!

Answer:
metal to non metal ratio is 97/21 = 4.62 or
82.2% metals, 17.8% non metals
Explanation:
How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference. (learning about the periodic table if...
of 118 elements in the periodic table , 21 are non metals (even H has metallic properties when approching 0 degrees K)
this means there ar 21 nonmetals and 118-21=97 metals.
Answer:
Please see the attached pictures.
