Points) Determine the molar mass of NaCl (the solute) in a 0.1M aqueous solution of NaCl

nalin [4]

Answer:

58.443 g/mol

Explanation:

The molar mass of NaCl is the sum of the molar masses of the individual atoms:

Na: 22.989770 g/mol

Cl: 35.453 g/mol

The total molar mass is ...

NaCl: 58.443 g/mol

The molar mass does not depend on whether the material is in solution or in any other form.

Which of the following alcohols will give a positive chromic acid test?

Sindrei [870]

The answer is both B and C

positive chromic acid test is indicated by disappearance of orange colour from chromic ions and appearance of blue-green color from Chromium (iii) ion (reduction of chromium ion from CrO4 - to Cr3+)

positive chromic test indicated functional groups that can be oxidized.

cyclohexanol can be oxidized to become cyclohexanone

and pentan-3-ol can be oxidized to become pentan-3-one

hence both B and C will show positive chromic acid test

A) tert butanol although contains alcohol functional group, cannot be further oxidized as it is a tertiary alcohol

Equation balancing

meriva

Answer:

For a: The balanced equation is $2S(s)+3O_2(g)\rightarrow 2SO_3(g)$

For c: The balanced equation is $2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)$

Explanation:

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
