A student placed 2 drops of an unknown sample in a test tube and added 2 mL of ethanol to the test tube while mixing gently. The
Tatiana [17]

Answer:

2-propanol

Explanation:

From the given information

2 drops of an unknown sample were said to be placed in a test tube followed by the addition of 2 ml of ethanol then gentle mixing. They then initiate a further addition of  2 drops of potassium permanganate reagent (KMNO₄) to the test tube and mixed the contents of the test tube thoroughly. After adding 2 drops of potassium permanganate reagent, the reagent oxidizes the secondary alcohols(2-propanol) to ketone(i.e acetone) and no further reaction will take place since there are no reactive C-H bonds left. The diagram attached below shows how the reaction proceeds.

Alex Ar [27]

Answer: 1.10x10²³ atoms of C

110202600000000000000000 atoms C

Explanation:The solution process is shown below.

0.183 mole C x 6.022x10²³ atoms C / 1 mole C

= 1.10x10²³ atoms C

or 110202600000000000000000 atoms C

The density of acetic acid is 1.05 g/mL. What is the volume of 327 g of acetic acid
Eva8 [605]

Answer:

311.43\ \text{mL}

Explanation:

\rho = Density of acetic acid = 1.05\ \text{g/mL}

m = Mass of acetic acid = 327\ \text{g}

V = Volume

Density is given by

\rho=\dfrac{m}{V}\\\Rightarrow V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{327}{1.05}\\\Rightarrow V=311.43\ \text{mL}

The volume of acetic acid is 311.43\ \text{mL}.
