You would need to include your bullet points in the diagram

Bonding is demonstrated using electron dot diagrams by representing the valence electrons that form bonds.

What do you mean by Bonding?

Atoms in molecules are joined by a chemical bond.  Electrostatic forces between negatively charged electrons and positively charged atomic nuclei give rise to bonds.

An electron dot diagram is a representation of the arrangement of valence electrons around an atomic symbol.

The outermost shell contains valence electrons, which are electrons. By representing the valence electrons, which are the ones responsible for bonding, in electron dot diagrams bonding is demonstrated.

Express the measurement 0.530060 g three significant figures

Answers

Answer:

0.530 g.

Explanation:

The express the measurement 0.530060 g we need to remember first that:

- The zeros to the left of the amount do not count as significant figures

- All non-zero numbers count as significant figures

- The zeros that are between digits significants are significant figures

Hence, the three significant figures of the measurement 0.530060 g are:

0.530060 g = 0.530 g            

Therefore, the three significant figures of the measurement 0.530060 g are 0.530 g.

2) The two solid blocks represented in the diagram are made of the same material and are under the same temperature and pressure conditions. If the mass of block X is 54 grams, what is the mass of block Y? ​

Answers

Answer:

54 g

Explanation:

We'll begin by calculating the density of X. This can be obtained as follow:

Mass of X = 54 g

Length (L) = 9 cm

Breadth (B) = 2 cm

Height (H) = 1 cm

Volume of X = L × B × H

Volume of X = 9 × 2 × 1

Volume of X = 18 cm³

Density of X =?

Density = mass /volume

Density of X = 54/18

Density of X = 3 g/cm³

Finally, we shall determine the mass of Y as follow:

Length (L) = 3 cm

Breadth (B) = 3 cm

Height (H) = 2 cm

Volume of Y = L × B × H

Volume of Y = 3 × 3 × 2

Volume of Y = 18 cm³

Density of Y = Density of X (since they are made of the same material)

Density of X = 3 g/cm³

Density of Y = Density of X = 3 g/cm³

Mass of Y =.?

Density = mass /volume

3 = mass of Y /18

Cross multiply

Mass of Y = 3 × 18

Mass of Y = 54 g

Answer: 54

Which particle diagram represents the arrangement of F₂ molecules in a sample of fluorine at 95 K and standard pressure?

Answers

I'm pretty certain the answer is 2) because fluorine is a diatomic gas meaning it travels with 2 molecules (simplified). It is a gas so molecules should also be spread out so the answer cannot be 3) or 4).

Hope this helps! :)

Fluorine is a halogen that is the lightest and is highly toxic. Moreover, it exists in diatomic state.

At standard temperature and pressure, fluorine exists as gas.Fluorine exists as a diatom, i.e. [tex]F_{2}[/tex].It exists in gaseous form and thus, the molecules of this gas are far apart.

Thus, it can be concluded that the particle diagram 2 best represents the fluorine gas in the given temperature and pressure.

Hence, the correct answer is option 2.

What is the color and wavelength of light with 2.88 x 10-19 J of energy?

Answers

Answer : The color and wavelength of light is red and [tex]6.9\times 10^{-7}m[/tex] respectively.

Explanation :

Given:

Energy = [tex]2.88\times 10^{-18}J[/tex]

Now we have to determine the wavelength of light.

Formula used:

[tex]E=\frac{hc}{\lambda}[/tex]

where,

E = energy

h = Planck's constant = [tex]6.626\times 10^{-34}J.s[/tex]

c = speed of light = [tex]3\times 10^8m/s[/tex]

[tex]\lambda[/tex] = wavelength of light

Now putting all the given values in this formula, we get:

[tex]2.88\times 10^{-18}J=\frac{(6.626\times 10^{-34}J.s)\times (3\times 10^8m/s)}{\lambda}[/tex]

[tex]\lambda=6.9\times 10^{-7}m[/tex]

From the electromagnetic spectrum we conclude that the color of the light will be red of wavelength [tex]6.9\times 10^{-7}m[/tex].

Therefore, the color and wavelength of light is red and [tex]6.9\times 10^{-7}m[/tex] respectively.

Answers

Answer:

C.this is an exothermic reaction because energy is released

Explanation:

The explosion of gasoline in a car engine is an exothermic reaction.

An exothermic reaction is one in which heat is given out to the environment. That means, heat is released during the reaction.

When gasoline undergoes controlled explosion in car engines, heat is released, hence the answer.
