Answer:

1. Uniform, non visible

2. Visible, non uniform

3. Uniform, non visible

4. Visible, non uniform

5. Visible, non uniform

Explanation:

A heterogeneous mixture is simply any mixture that is not uniform in composition — it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogenous mixture

visible state of matter is when you can easily difference two components of a mixture

non visible is when the state of the matter in the substance is not visible to the eye, it can't be differentiated

Compare Dobereiner’s triads to the modern periodic table. What aspects of his idea agreed with the modern table and what aspects
iVinArrow [24]

Answer:

In  Dobereiner’s triads, elements were placed :

  • According to increasing order of their atomic masses.
  • Into groups which have similar chemical and physical properties.
  • In each group there were three elements.

In Modern periodic table, elements are placed:

  • According to increasing order of their atomic numbers.
  • Into groups and these groups are assigned according to the numbers of valence electrons present in their valence shell.

Aspects of Dobereiner’s triads agreed with the modern periodic table

  • Element of the same group will have similar chemical and physical properties.

Disagreement with the modern periodic table.

  • Not all groups obeyed law of triads.
  • On the basis of properties all known elements could not be classified into groups of triads.

Which type of substance will have the highest boiling point? Select the correct answer below:
nalin [4]

Answer: Option (c) is the correct answer.

Explanation:

Polar molecules are defined as the molecules that chemically combine together and have partial opposite charges.

For example, H_{2}O is a polar molecule as due to the difference in electronegativity of hydrogen and oxygen atom there is partial positive charge on hydrogen atom and partial negative charge on oxygen atom.

On the other hand, molecules which are neutral in nature are known as non-polar molecules. A non-polar molecule is formed by equal sharing of electrons.

For example, CCl_{4} is a non-polar molecule.

As in a large polar molecule, there will be greater force of attraction between the oppositely charged ions due to large surface area. Hence, large amount of heat needs to given in order to break the bonds.

Therefore, we can conclude that a large polar molecule will have the highest boiling point.
