Oxaloacetic acid (2-ketosuccinic acid) is a very important intermediate in metabolism. The compound is involved in the citric ac

id cycle for energy production within the cell. However, the compound is unstable and slowly decomposes spontaneously. Draw the decomposition products.

Answer:

Carbon dioxide and acetoacetic acid

Explanation:

Oxaloacetic acid is a β-keto acid. It decarboxylates readily via a six-membered cyclic transition state.

The initial products are carbon dioxide and the enol of a ketone.

The enol is unstable and rapidly tautomerizes to the more stable keto form — acetoacetic acid.

A student combined two colorless aqueous solutions. One of the solutions contained Na2CO3 as the solute and the other contained
Kazeer [188]

Answer:

Bubbles will be formed when two solutions will be combined.

Explanation:

When the solution containing Na_{2}CO_{3} and HCl as a solute will be combined, the reaction will be as follows,

Na_{2}CO_{3}(aq) + 2HCl(aq) \rightarrow   2NaCl(aq)+ H_{2}O(l)+CO_{2}(g)

As a result of combination of the two solutions bubbles will be formed which will depict the evolution of carbon dioxide gas.

A 13.5 g sample of an unknown gas occupies 5.10 L at 149.83 kPa and 301 K. What is the molar mass of the gas ?
alisha [4.7K]

Answer:

The molar mass of the gas is 44.19 g/mol

Explanation:

Amount of sample of gas = m = 13.5 g

Volume occupied by the gas = V = 5.10 L

Pressure of the gas = P = 149.83 KPa

1 KPa = 0.00986 atm

P = 149.83 \textrm{ KPa} \times 0.00986 \textrm{ atm/KPa} = 1.48 \textrm{ atm}

Assuming M g/mol to be the molar mass of the gas

Assuming the gas is behaving as an ideal gas

\textrm{PV} =\textrm{nRT} \\\textrm{PV} = \displaystyle \frac{m}{M}\textrm{ RT } \\1.48 \textrm{ atm}\times 5.10 \textrm{ L} = \displaystyle \frac{13.5 \textrm{ g}}{M}\times 0.0821 \textrm{ L.atm.mol}^{-1}.K^{-1}\times 301\textrm{K} \\M = 44.19 \textrm{ g/mol}

The molar mass of gas is 44.19 g/mol
