Answer:

I believe that the answer is the paint absorbed the energy from the light

Explanation:

The paint dried because the paint absorbed the energy from the light and the correct option is option D.

Light absorption is the process in which light is absorbed by matter and converted into energy. In an atom, electrons vibrate at a specific frequency – this is called the natural frequency.

If a wave of light hits a material in which the electrons are vibrating at the same frequency as the wave of light, the electrons will absorb the energy and convert it into vibrational motion.

This is why objects have different colours – different materials’ electrons will vibrate at different rates, and therefore absorb different frequencies of light.

Therefore, the paint dried because the paint absorbed the energy from the light and the correct option is option D.

Answer:

Neutrons and protons

Explanation:

There are three fundamental subatomic particles, these are;neutrons protons and electrons.

Ernest Rutherford successfully showed that every atom does possess a central core that contain positively charged particles (protons) called the nucleus. Chadwick later discovered the existence of neutrons.

Both protons and neutrons are found in the nucleus. Z represents the nucleus of the boron atom and houses the neutrons and protons of the boron atom.

Explanation:

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

[tex]n = \frac{N}{L} \\[/tex]

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

We have

[tex]n = \frac{2.4 {10}^{23} }{6.02 \times {10}^{23} } = \frac{2.4}{6.02} \\ = 0.3986...[/tex]

Answer:

150 mL

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 10 M

Volume of diluted solution (V₂) = 3 L

Molarity of diluted solution (M₂) = 0.5 M

Volume of stock solution needed (V₁) =?

The volume of stock solution needed can be obtained as follow:

M₁V₁ = M₂V₂

10 × V₁ = 0.5 × 3

10 × V₁ = 1.5

Divide both side by 10

V₁ = 1.5 / 10

V₁ = 0.15 L

Finally, we shall convert 0.15 L to mL. This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.15 L = 0.15 L × 1000 mL / 1 L

0.15 L = 150 mL

Therefore, the volume of the stock solution needed is 150 mL

Answer:

It would be to low

Explanation:

If some salt were accidently spilled as it was transferred from  balance to  cup  calculated enthalpy of solution of salt be too low as there will be loss in mass  which would lead less solubility of salt and hence less enthalpy.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Answer:

0.20 moles

Explanation:

In order to solve this problem it is necessary to keep in mind the definition of molarity:

If we input the data given by the problem we're left with:

Meaning that we can proceed to calculate the number of moles:

The number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution is 0.2 moles.

Given the following data:

To determine the number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution:

Mathematically, the molarity of a solution is given by the formula:

[tex]Molarity = \frac{number\;of\;moles}{Volume \;in\;liters}[/tex]

Making number of moles the subject of formula, we have:

[tex]Number\;of\;moles = Molarity \times Volume[/tex]

Substituting the given parameters into the formula, we have;

[tex]Number\;of\;moles = 0.40 \times 0.500[/tex]

Number of moles = 0.2 moles.
