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:
12.5% is left
Explanation:If the half-life of a reaction is 6 days. What percentage of material is left after 18 days?
18 days/6 days = 3 half lives
each half life you lose half the material
in 3 half lives you have (1/2)x (1/2) x (1/2) =1/8
1/8 =0.125 so 12.5% is left
