Answer:

A, B

Explanation:

A) This statement is consistent with Rutherford's nuclear theory as atom is mostly an empty space with tiny particles spread round. Exactly like our solar system in space, where sun be considered as nucleus containing neutron and proton and planets as electrons.

B) Yes ratio of size of atom to nucleus is 100000 is to 1. So, nucleus is quite smaller than the atom.

C) This is inconsistent with Rutherford's nuclear theory as till that time theory of neutron was not discovered.

D) An atom is neutral when no. of electrons( negative charge) is equal to no. of protons(positive charge). Therefore, it is inconsistent.

How many electrons does nitrogen (N) need to gain to have a stable outer electron shell

earnstyle [38]

It need "3 electrons" to have a stable electronic configuration.

'cause it has 5 electrons in it's outer shell & every atom needs 8 electrons. So, it requires 3 more!

Hope this helps!

When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solutio

8090 [49]

Answer:

Volume of stock solution needed = 6.0299 mL

Explanation:

<u> </u>Dilution consists of lowering the amount of solute per unit volume of solution. It is achieved by adding more diluent to the same amount of solute.

This is deduced when thinking that both the dissolution at the beginning and at the end will have the same amount of moles.

M1 = 6.01 M stock solution concentration

M2 = 0.3624 M diluted solution concentration

V2 =100 mL diluted solution volume

V1 = ? stock solution volume

M1 * V1 = M2 * V2

$V1=\frac{M2*V2}{M1} =\frac{0.3624M*100mL}{6.01M} =6.0299 mL$

What is the missing value

Korvikt [17]

Answer:

Explanation:

The pattern here may be hard to find at first, but it's this: the number in the middle of the triangle = (number at lower left corner of triangle x number at upper vertex of triangle) + (number at upper vertex of triangle x number at lower right corner of triangle).

Thus, for the missing value...

Missing value = (3x8) + (8x6) = 24+48 = 72.

Could you tell me what concept in chemistry relates to this? I'm interested.

Also check out stylesben's answer. Seems like there's several ways of doing this.
