6) What is the picture below an example of?

Answer:

Using the drop down Menu

Proton : Possessing a Charge of +1. It is found in the Nucleus and has a Mass of "A"

Neutron; Possesses a charge of 0. It is situated in the Nucleus and Has a Mass of "B"

Electron: Has a charge of -1. Found in the Orbitals of the atom and has a mass of "C"

Answer:

12 g/mol

Explanation:

From Avogadro's law;

V1/n1 = V2/n2

V1 =  5.0 dm^3

n1 = 15 g/26 g/mol = 0.6 moles

V2 = 1.0 dm^3

n2 = ?

V1n2 = V2n1

n2 = V2n1/V1

n2 = 1 * 0.6/5

n2 = 0.12 moles

Molar mass= mass of gas D/number of moles of gas D

Molar mass= 1.4 g/0.12 moles

Molar mass= 12 g/mol

The complete question is: Is the compound [tex]FeCl_{3}[/tex] ionic or covalent ?

Answer: Compound  [tex]FeCl_{3}[/tex] is an ionic in nature.

Explanation:

When a metal atom combines with a non-metal atom then transfer of electrons take place from metal towards the non-metal. As a result, an ionic bond is formed between the atom and compound formed is called an ionic compound.

For example, [tex]FeCl_{3}[/tex] compound contains Fe atom which is a metal and Cl atom which is a non-metal. Hence, electrons will be transferred from Fe atom to the Cl atom forming an ionic bond.

Hence, [tex]FeCl_{3}[/tex] is an ionic compound.

Thus, we can conclude that [tex]FeCl_{3}[/tex] is an ionic compound.

Explanation:

The given costs for the purchase and delivery of the cupcakes are;

The cost of 10 cupcakes and the delivery fee = $30

The cost of 25 cupcakes and the delivery fee = $67.50

Let 'c' represent the fixed cost of delivery of the cup cakes, and let 'x' represent the cost of each cup cake, we have;

30 = 10·x + c...(1)

67.50 = 25·x + c...(2)

Subtracting equation (1) from equation (2) gives;

67.50 - 30 = 37.50 = 25·x - 10·x + c - c = 15·x

∴ x = 37.50/15 = 2.5

The cost of each cupcake, x = 2.5

(∴ The delivery fee = 30 - 10 × 2.5 = 5)

The cost of each cupcake is 2.5.

Answer:

1) It gets slower the farther out they are.

2) The farther out you are from the sun the less gravitational pull you have, which makes it go slower as it orbits.

3) Gravity ;) :)

Explanation:

Hope this helps! Plz mark as brainliest! :)

1.) The four inner planets have slower orbits and the four outer planets have faster orbits.

2.) The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves.

3.) Gravity

Answer:

[tex]\boxed {\boxed {\sf 0.0014 \ mol \ Cu}}[/tex]

Explanation:

We are asked to convert particles to moles.

1 mole of any substance contains the same number of particles (atoms, molecules, formula units). This is Avogadro's Number or 6.022*10²³.

In this problem, the particles are atoms of copper. So, 1 mole of copper contains 6.022*10²³ atoms of copper

Use Avogadro's Number to make a ratio.

[tex]\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}[/tex]

We are trying to convert 8.3*10²⁰ atoms of copper to moles, so we multiply that value by the ratio.

[tex]8.3*10^{20} \ atoms \ Cu*\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}[/tex]

The units of "atoms Cu" will cancel.

[tex]8.3*10^{20}\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} }[/tex]

Condense the expression into 1 fraction.

[tex]\frac{8.3 *10^{20}}{ 6.022*10^{23} } \ mol \ Cu[/tex]

[tex]0.001378279641 \ mol \ Cu[/tex]

The original measurement of atoms has 2 significant figures, so our answer must have the same. For the number we calculated that is the ten-thousandths place.

The 7 in the hundredth thousandth place tells us to round the 3 up to a 4.

[tex]0.0014 \ mol \ Cu[/tex]

8.3*10²⁰ atoms of copper are equal to 0.0014 moles of copper.

Answer:

[tex]P_2=7.09atm[/tex]

Explanation:

Hello!

In this case, given the change in volume and pressure of the gas, it is possible for us to recall the Boyle's law as way to understand the inversely proportional relationship between pressure and volume:

[tex]P_1V_1=P_2V_2[/tex]

Thus, when solving for the final pressure, P2, given the initial pressure and volume and the final volume, we obtain:

[tex]P_2=\frac{P_1V_1}{V_2}\\\\P_2=\frac{2.27atm*2.50L}{0.80L}\\\\P_2=7.09atm[/tex]

Best regards!

Answer:

7.1 atm

Using Boyle’s law, P1 V1=P2 V2.

Answer:

V = 50.77 L

Explanation:

Given that,

No. of moles, n = 2

Pressure, P = 0.947 atm

Temperature, T = 20°C = 293 K

We need to find the volume occupies by Nitrogen gas. Using gas law,

[tex]PV=nRT\\\\V=\dfrac{nRT}{P}[/tex]

Where

R is gas constant

Put all the values,

[tex]V=\dfrac{2\times 0.08205\times 293}{0.947}\\\\V=50.77\ L[/tex]

So, the volume occupied by the gas is equal to 50.77 L.

Answer:

cis-2-pentene

Explanation : The stereoisomers are the compound which differs only in the spatial arrangement of the atoms across the stereogenic centers.

There are mainly two forms of stereoisomers cis and trans. Cis-isomers are those where the two bulky or functional groups are arranged on the same side across the stereogenic center; whereas, in trans-isomers the two bulky groups or functional groups are arranged in the opposite sides of stereogenic center.
