Explanation:
Below is an attachment containing the solution.
The effective speed (rms) of the oxygen gas is 293.68 m/s.
<h3></h3><h3>What is Root-mean-square velocity?</h3>Root mean square velocity is the square root of the mean of squares of the velocity of individual gas molecules
<em>where </em>R = universal gas constant
M = molar mass of the gas in kg/mol
T = temperature in Kelvin
According to the ideal gas law,
PV = nRT
RT =
Substitute in the rms velocity formula,
P = 92 kPa, V = 10 L, n = 2 moles and M = 32 x 10⁻³ kg/mol
=293.68 m/s
Thus, the effective speed (rms) of O₂ gas is 293.68 m/s.

Answer:
The IUPAC name of the compound has already been given which is 2,2-dimethyl-4-ethylheptane.
Explanation:
The IUPAC (International Union of Pure and Applied Chemistry) is an authority in chemistry that provides a guideline and standardized methods in the naming of compounds formed from the periodic table.
In order the give an IUPAC name to a compound, certain steps needs to be followed, these includes:
--> Identify the functional group in the compound as this will form the suffix. For example if the functional group is an alkane the suffix will be -ane.
--> Identify the longest carbon chain (it may not be a straight chain) that contains the functional group. This forms the prefix. Example: if the longest carbon chain is 7 carbon atoms then the prefix will be hept-
--> All the carbons of the longest chain should be numbered
--> Identify branched groups on the chain and name them according to the number of carbon atoms. They usually end with -yl.
--> Finally, combine the elements of the name is a single word.
The structural formula of the IUPAC compound can be found in the attached file for a better understanding. The branched groups are circled.
