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.

Explanation:

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:

70g of Pb(NO3)2 would need to be added

Explanation:

As you can see in the solubility graph of lead nitrate, Pb(NO₃)₂, the solubility of this salt (That is, the maximum amount of the salt that can be dissolved in 100g of the solvent producing a homogeneous solution) is 70g in 100g of water = 70g of the salt in 100mL of water.

A saturated solution is also defined as solubility: The maximum amount of a solute that can be dissolved in a solvent.

That means:

70g of Pb(NO3)2 would need to be added

Answer:

Por formación de burbujas.

Explicación:

La presencia de burbujas en la superficie de la bebida ayuda a determinar si la bebida tiene gas carbonatado o dióxido de carbono. El gas de dióxido de carbono no se puede mezclar con agua ni disolver en agua normalmente. Se puede agregar mediante alta presión al agua para que cuando se coloquen en condiciones normales, el dióxido de carbono se libere en forma de burbujas. No, el gas hidrógeno y el gas hidrógeno no podrían formar agua carbonatada porque ambos son átomos diferentes. El agua carbonatada tiene gas dióxido de carbono, no gas hidrógeno.

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:

two or more substances that are visibly distinguishable.

Answer: There is 125 mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution

Explanation:

Given: [tex]M_{1}[/tex] = 2.0 M,      [tex]V_{1}[/tex] = ?

[tex]M_{2}[/tex] = 0.5 M,       [tex]V_{2}[/tex] = 500 mL

Formula used to calculate the volume is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\2.0 M \times V_{1} = 0.5 M \times 500 mL\\V_{1} = 125 mL[/tex]

Thus, we can conclude that there is 125 mL of a 2.0 M [tex]CuCl_{2}[/tex] solution are needed to make 500 mL of a 0.5 M solution.

Answer:

22.4 L

Explanation:

We'll begin by calculating the number of mole in 16.0 g of CH₄. This can be obtained as follow:

Molar mass of CH₄ = 12 + (4×1)

= 12 + 4

= 16 g/mol

Mass of CH₄ = 16 g

Mole of CH₄ =?

Mole = mass / molar mass

Mole of CH₄ = 16 / 16

Mole of CH₄ = 1 mole

Finally, we shall determine the volume of the gas. This can be obtained as follow:

Number of mole of CH₄ (n) = 1 mole

Pressure (P) = 760 mmHg = 1 atm

Temperature (T) = 0°C = 273 K

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V)?

PV = nRT

1 × V = 1 × 0.0821 × 273

V = 22.4 L

Therefore, the volume of the gas is 22.4 L

Answer:

Human activity is by far the biggest cause of habitat loss.

Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. ... Human activity often changes or destroys the habitats that plants and animals need to survive.

Explanation:

Human activities are the various actions for recreation, living, or necessity done by people. For instance it includes leisure, entertainment, industry, recreation, war, and exercise.

Over time, destruction of such habitats leads to reduced biodiversity, weakening the Earth's ecosystems, and ultimately posing a major threat to human life. While, significant tracts of habitat have been lost, and along with them many species of plant and animal, steps can be taken to slow and even reverse the process.

One of the most significant ways in which humans have impacted on the lives of other species is by causing climate change. Many animals, including birds and frogs, now breed much earlier in spring in Britain than they did 20 years ago. Whether or not this is having a harmful effect on them has yet to be determined.

Answer:

The volume of the gas is approximately 4.41 liters

Explanation:

The details of the data of the Neon gas are;

The number of moles of Neon gas present, n = 11.6 moles

The temperature of the sample of Neon gas, T = 120 K

The pressure of the sample of the Neon gas, P = 25.6 atm

By the ideal gas equation, we have;

P·V = n·R·T

Where;

R = The universal gal constant = 0.08205 L·atm·mol⁻¹·K⁻¹

Therefore, we get;

V = n·R·T/P

Which gives;

V = 11.6 moles × 0.08205 L·atm·mol⁻¹·K⁻¹ × 120 K/(25.9 atm) ≈ 4.4097915 L

The volume of the gas, V ≈ 4.41 L.

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:

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.
