Answer : The correct option is, (C) 0.6 ml

Explanation : Given,

Initial volume of solution in the burette = 32.3 ml

Final volume of solution in the burette = 32.9 ml

As the liquid is colorless. So, we are taking the lower meniscus for the correct reading of the solution.

Now we have to calculate the total volume of solution that was dispensed from this burette.

\text{Total volume of solution dispensed}=\text{Final volume of solution in the burette}-\text{Initial volume of solution in the burette}

Now put all the values in this formula, we get the total volume of solution that was dispensed from this burette.

\text{Total volume of solution dispensed}=32.9ml-32.3ml=0.6ml

Therefore, the the total volume of solution that dispensed from this burette was, 0.6 ml

Diano4ka-milaya [45]

Answer:

3.14

Explanation:

A student was comparing two samples with an equal number of carbon atoms. One sample contained only Carbon-12 atoms. One sample contained only Carbon-14 atoms, which contain two more neutrons than Carbon-12 atoms. The student measured the mass of each sample and testing the reactivity of each sample.

Required:

What would best describe the results of the investigation?

) If you started with 2.3182 g of 3-nitrophthalic acid and had a 93% yield of 3-nitrophthalhydrazide, how many grams of 3-nitrop
MArishka [77]

Answer: 1.8124 g of 3-nitrophthalhydrazide were recovered.

Explanation:

The balanced chemical reaction will be :

C_8H_5NO_6+N_2H_4\rightarrow C_8H_5N_3O_4+2H_2O

moles of 3-nitrophthalic acid  = \frac{\text {given mass}}{\text {molar mass}}=\frac{2.3182g}{211.13g/mol}=0.0110mol

As 1 mole of 3-nitrophthalic acid gives = 1 mole of 3-nitrophthalhydrazide

0.0110 moles of 3-nitrophthalic acid gives = \frac{1}{1}\times 0.0110=0.0110 mole of 3-nitrophthalhydrazide

mass of 3-nitrophthalhydrazide = moles\times {\text {molar mass}}=0.0110mol\times 177.16g/mol=1.9488g

As the percentage yield is 93% , the mass of 3-nitrophthalhydrazide recovered = \frac{1.9488\times 93}{100}=1.8124g

Therefore 1.8124 g of 3-nitrophthalhydrazide were recovered.
