Which acid is stronger propanoic or Methanoic?

Which acid is stronger propanoic or Methanoic?

Ka for propanoic acid is 1.34 × 10–5, and Ka for methanoic acid is 1.77 × 10– 4. For acids, the larger the value of Ka , the greater the strength; therefore methanoic acid is the stronger acid because 1.77 × 10– 4 > 1.34 × 10–5.

What is a 5 on AP Chem?

Scores of 3, 4, or 5 are considered “passing” scores on the AP® Chemistry Exam. The College Board describes a 3 as ‘qualified,’ 4 as ‘well qualified,’ and a 5 as ‘extremely well qualified.

Is the pressure in the container holding H2?

our answer. The pressure in the container holding the H2(g) is equal to the pressure in the container holding the N2(g) because there is an equal number of moles of both gases at the same temperature One point is earned for the correct choice.

Is AP Chem memorization?

There’s a lot of material covered in AP Chemistry. The course involves memorization of complex principles, mastery of specific mathematical skills, and the ability to visualize interactions between tiny things that can only be represented abstractly.

Why is methanoic acid a weak acid?

Carboxylic acids are weak acids. This means that their solutions do not contain many hydrogen ions compared with a solution of a strong acid with the same concentration .

Which is more acidic Methanoic or ethanoic acid?

CH3, being an alkyl group, would exert electron donating inductive effect on its neighboring COO- group, intensifying the negative charge on O atom. Electron donating in ethyl group more than methyl group. Therefore, methanoic acid more acidic than ethanoic acid.

What is the longest AP test?

The total length of AP exams ranges from 1 hour and 30 minutes to 3 hours and 15 minutes….How Long Is Each AP Exam?

Exam Total Length
Calculus BC 3 hours 15 minutes
Chemistry 3 hours 15 minutes
Chinese Language and Culture 2 hours 15 minutes
Comparative Government and Politics 2 hours 25 minutes

Why does he escape faster than ne?

He(g) will escape faster because the He(g) atoms are moving at a higher average speed than the Ne(g) atoms. Ne(g) will escape faster because its initial pressure in the container is higher. Ne(g) will escape faster because the Ne(g) atoms have a higher average kinetic energy than the He(g) atoms.

What is the average kinetic energy of the H2 G molecules?

The average kinetic energy of the H2(g) molecules is 6.2 × 10−21 J because both gases are at the same temperature.

What is the functional group of methanoic acid?

For example, the IUPAC name for formic acid is methanoic acid – the ‘methan’ specifies that there is one carbon (it is a derivative of methane, CH4) and the ‘oic acid’ tell us that the functional group is a carboxylic acid (i.e. that it contains a –CO2H group).
