Answer:

The molar mass of the unknown gas is 128g/mol

Explanation:

The rate of effusion of 2 different gases follows the equation:

Rate gas A / Rate gas B = √MM gas B / √MM gas A

<em>Where rate is the speed of effusion of each gas and MM the molar mass of each gas</em>

<em />

If gas A is oxygen and gas B the unknown:

Rate gas A / Rate gas B = 2 = √MM gas B / √32g/mol

11.134 = √MM gas B

128g/mol = MM gas B

The molar mass of the unknown gas is 128g/mol

For H3PO4, Ka1 = 7.3 x 10^-3, Ka2 = 6.2 x 10^-6, and Ka3 = 4.8 x 10^-13. A 0.10 M aqueous solution of Na3PO4 therefore would be
zmey [24]

Answer:

The aqueous solution of Na_{3} Po_{4} therefore would be "strongly basic."

Explanation:

Strongly basic because the Na_{3} Po_{4} is completely an ionic compound. These compound can be 100% splitted into metal ions and hydroxide ion when used in the aqueous solution. Each moles dissolves which can give rise to mole of hydrogen ions when used in the solution. Whereas strong bases are not soluble in water as well.  in the presence of water equilibrium can also be achieved. A strong base has the capability which can just remove the proton from the molecule.

Compounds X and Y are both C7H15Cl products formed in the radical chlorination of 2,4-dimethylpentane. Base-promoted E2 eliminat
saul85 [17]

Answer:

X  is 3-chloro-2,4-dimethylpentane

Explanation:

The radical chlorination of 2,4-dimethylpentane may give three products.

Based on the information that

i) both the products gives single alkene on elimination and

ii) both the products also undergoes SN2 reaction but Y reacts faster than X

We may conclude that as SN2 reaction is faster in primary alkyl halides as compared to secondary or tertiary so Y must be primary or secondary and it cannot be tertiary alkyl halide.

The possible products are shown in the figure.

The structure of X is shown in the figure.
