Which of the following is not a part of the ideas john dalton proposed in his model

NNADVOKAT [17]

The following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

Law of conservation of mass
Law of definite proportion
Law of multiple proportion

Thus, the following which is not a part of Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

Is tap water a heterogeneous or homogenous mixture? Explain your answer.

Tomtit [17]

A homogeneous mixture has the same uniform appearance and composition throughout. A heterogeneous mixture consists of visibly different substances or phases. Homogeneous mixtures

So the answer is heterogeneous.

Draw the best Lewis structure of CH3NO2, a neutral compound. Draw the Lewis structure by placing atoms on the grid and connectin

steposvetlana [31]

Answer : The Lewis-dot structure of $CH_3NO_2$ is shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $CH_3NO_2$

As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron, nitrogen has '5' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in $CH_3NO_2$ = 4 + 3(1) + 5 + 2(6) = 24

According to Lewis-dot structure, there are 14 number of bonding electrons and 10 number of non-bonding electrons.

Now we have to determine the formal charge for each atom.

Formula for formal charge :

$\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}$
