Mole fraction of the solute in a 1.00. What is the molal aqueous eqaution?

Chemistry
1 answer:
Troyanec [42]3 years ago
6 0
Mole fraction is expressed as the number of moles of solute over the total number of moles of solute and the number of moles of solvent. When expressed in molal, this is equal to number of moles of solute per liter solvent. If the mole fraction is 1.00, this means, all that is in the solution is solute. Hence the molal equivalent is 1.00 too

Vlad [161]

The question is incomplete, the complete question is:

Which statements are consistent with Dalton's atomic theory as it was originally stated? Why?

a. Sulfur and oxygen atoms have the same mass.

b. All cobalt atoms are identical.

c. Potassium and chlorine atoms combine in a 1:1 ratio to form potassium chloride.

d. Lead atoms can be converted into gold.

<u>Answer: </u>The correct options are b) and c).

<u>Explanation:</u>

Some of the postulates of Dalton's atomic theory are:

  • All matter is made of very tiny particles called atoms that participate in chemical reactions
  • Atoms are indivisible particles that cannot be created or destroyed in a chemical reaction
  • Atoms of a given element are identical in mass and chemical properties
  • Atoms of different elements have different masses and chemical properties.
  • Atoms combine in the ratio of small whole numbers to form compounds.
  • The relative number and kinds of atoms are constant in a given compound.

For the given options:

<u>For a:</u>

The statement is inconsistent with the theory as no two elements can have the same mass. Only atoms of the same element can have the same mass.

  • <u>For b:</u>

This is consistent with the theory as atoms of the same element are identical.

  • <u>For c: </u>

This is consistent with the theory as atoms combine in a simple whole number ratio.

  • <u>For d:</u>

The statement is inconsistent with the theory as atoms of one element cannot be changed to atoms of other element.

Hence, the correct options are b) and c).

ira [324]
Answer:
            But-2-enoic acid has 11 Sigma Bonds and 2 Pi Bonds.

Explanation:
                   The sigma bonds which are formed due to head to head overlap of partally filled orbitals are shown in red color, while Pi bonds which are formed after the formation of sigma bond by overlap of orbitals perpendicular to the sigma bond are shown in blue color.
