Which statement best describes the kinetic molecular
prohojiy [21]

Answer:

A. The kinetic molecular theory relates the properties of a state of matter to the motion of  its molecules.

Explanation:

The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.

How many moles are in 1.9 x 1046 atoms of chromium?
faust18 [17]

Answer:

<h2>3.156 × 10²² atoms</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1.9 \times  {10}^{46} }{6.02 \times  {10}^{23} }  \\  = 3.156 \times  {10}^{22}

We have the final answer as

<h3>3.156 × 10²² atoms</h3>

Hope this helps you

Calculate the volume of 1 M NaOH needed to prepare 10.0 ml of a 0.10 M solution.
Mumz [18]
Answer is: <span>volume of 1 M NaOH is 1 ml.
</span>c₁(NaOH) = 1 M.
V₂(NaOH) = 10 ml.
c₂(NaOH) = 0,1 M.
V₁(NaOH) = ?
c₁ - original concentration of the solution, before it gets diluted.
c₂ - final concentration of the solution, after dilution.
V₁ - <span>volume to be diluted.
V</span>₂ - <span>final volume after dilution.
c</span>₁ · V₁ = c₂ · V₂.
V₁(NaOH) = c₂ · V₂ ÷ c₁.
V₁(NaOH) = 0,1 M · 10 ml ÷ 1 M.
V₁(NaOH) = 1 ml.

There are ________ σ bonds and ________ π bonds in h3c-ch2-ch=ch-ch2-c≡ch.
FrozenT [24]
The number of sigma and pi bonds are,

          Sigma Bonds  =  16

          Pi Bonds         =   3

Explanation:
                   Every first bond formed between two atoms is sigma. Pi bond is formed when already a sigma bond is there. While in case of Alkyne (triple Bond) there is one sigma and one pi bond already present, so the third bond is formed by second side-to-side overlap of orbitals, hence, a second pi bond is formed.
Below all black bonds are sigma bonds, while in alkene there is one pi bond and in alkyne there are two pi bonds.
