Find molarity of the solution:

Molarity is defined as the ratio between the moles of the solute (Lithium Chloride in this case) per liter of solution. To solve this question we have to find the moles of LiCl and its volume as follows:

Moles LiCl -Molar mass: 42.394g/mol-

2.3g * (1mol / 42.394g) = 0.0543 moles

Volume in liters:

500cm³ * (1L / 1000cm³) = 0.500L

Molarity:

0.0543 moles / 0.500L =

0.109M

Answer:

alpha < beta < gamma.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Generally, all radioactive elements are capable of emitting radiation. The three (3) types of nuclear radiation from least damaging to most damaging are; alpha, beta and gamma.

This ultimately implies that, alpha particles have the least damaging (penetrative) ability followed by beta particles and lastly, gamma rays.

Answer:

Number of atoms is equal.

Explanation:

1 mol of anything contains NA particles.

NA is known as Avogadro's number, 6.02×10²³

We determined the moles of each compound. Both molecules are dyatomic,

H₂  → 2.02 g . 1mol / 2.016 g = 1 mol

O₂ →  32 g . 1mol / 32g = 1 mol

Both have the same amount of moles.

In conclussion, the number of atoms is the same in both samples.

Answer:

0 kJ/mol

Explanation:

Step 1: Given data

Step 2: Calculate the Gibbs free energy change (ΔG)

We can calculate the Gibbs free energy change using the following expression.

ΔG = ΔH - T × ΔS

ΔG = 27 kJ/mol - 300 K × 0.09 kJ/mol.K = 0 kJ/mol

Since ΔG = 0 kJ/mol, the process in not spontaneous nor non-spontaneous.

Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.

Explanation:

Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.

As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.

Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.

As a result, silver chloride is not able to conduct electricity.

Answer:

C. So electrons can flow from one electrode to another

Explanation:

An electrochemical cell is any cell in which electricity is produced by reason of a chemical change.

An electrochemical cell consists of two electrodes, these two electrodes are connected using a wire.

Usually, electrons flow from one electrode to another via this wire thereby enabling the electrochemical processes of oxidation and reduction in the cell to proceed effectively.

In the buffer solution CH₃COOH (aq) ---> H₃O⁺(aq) + CH₃CO₂⁻(aq):

CH₃CO₂H is a base, and H₃O⁺ is its conjugate acid.

Option D is correct.

An acid is described as a molecule or ion capable of either donating a proton, known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid.

From the buffer solution above, H₃O⁺ is the conjugate acid because it donates a proton (H⁺) to a base CH₃CO₂H.

In conclusion, A conjugate acid, within the Brønsted–Lowry acid–base theory, is described as a chemical compound formed when an acid donates a proton (H⁺) to a base.

Answer:

94.2 g/mol

Explanation:

Ideal Gases Law can useful to solve this

P . V = n . R . T

We need to make some conversions

740 Torr . 1 atm/ 760 Torr = 0.974 atm

100°C + 273 = 373K

Let's replace the values

0.974 atm . 1 L = n . 0.082 L.atm/ mol.K . 373K

n will determine the number of moles

(0.974 atm . 1 L) / (0.082 L.atm/ mol.K . 373K)

n = 0.032 moles

This amount is the weigh for 3 g of gas. How many grams does 1 mol weighs?

Molecular weight → g/mol → 3 g/0.032 moles = 94.2 g/mol

Answer:

equal

Explanation:

Answer:

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]

Explanation:

Answer: The heat energy absorbed by the glass window is 84420 J.

Explanation:

Given: Mass = 15.0 kg (1 kg = 1000 g) = 15000 g

Specific heat capacity = [tex]0.840^{o}C[/tex]

Initial temperature = [tex]20^{o}C[/tex]

Final temperature = [tex]26.7^{o}C[/tex]

Formula used to calculate heat energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m =  mass of substance

C = specific heat capacity

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 15000 g \times 0.840J/g^{o}C \times (26.7 - 20.0)^{o}C\\= 84420 J[/tex]

Thus, we can conclude that heat energy absorbed by the glass window is 84420J.

Answer:

deforestation decreases biodiversity of the forest ecosystem

Explanation:

Deforestation has to do with the process of felling trees. This process destroys forest ecosystems. Deforestation is normally carried out for the purpose of development.

An ecosystem is a self supporting unit in which living and non living things interact. The different species of plants and animals found in an ecosystem is called biodiversity.

Since organisms in an ecosystem interact among each other and with their non-living environment, destruction of the trees in the forest ecosystem leads to the loss of certain species present in the ecosystem.

For instance, climbers and animals found on tree tops are normal components of a forest ecosystem. When trees are felled and the forest ecosystem is destroyed across the world, these organisms are threatened. This leads to loss of species or loss of biodiversity.

Answer:

Here’s one possible answer:

Deforestation will likely decrease the biodiversity of the forest ecosystem. It reduces the living space and food sources for some of the organisms. Scarcity of space and food may be a threat to the population of those organisms. Over time, some species may die off, leaving fewer species in the forest.
