How many mL of a 2.0 M CuCl2 solution are needed to make 500 mL of a 0.5 M solution?
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.

On a hot day, a 15.0 kg window increased from 20.0 degrees C to 26.7 degrees C. How much heat energy did the glass window absorb? (specific heat of glass = 0.840 J/gC)
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.

O
B. AG=-18 kJ/mol
O
C. AG= 0 kJ/mol
O
D. AG = 27 kJ/mol
Answer:
0 kJ/mol
Explanation:
Step 1: Given data
Enthalpy change (ΔH): 27 kJ/molEntropy change (ΔS): 0.09 kJ/mol.KAbsolute temperature (T): 300 KStep 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.
Al hacer reaccionar 5g de cinc con ácido sulfúrico se observa que la reacción ocurre en 20s. ¿Cuál será la rapidez de la reacción? Masa atómica del cinc 65,37g.
Answer:
0.0038 mole s-1
Explanation:
La velocidad de una reacción se refiere a la rapidez o la lentitud con que avanza una reacción. Se mide por la cantidad de reactivos que desaparecen por unidad de tiempo o por la cantidad de productos que aparecen por unidad de tiempo.
Número de moles de zinc = 5g / 65.37gmol-1 = 0.076 moles
Velocidad de reacción = 0.076 moles - 0 moles / 20 s - 0s = 0.0038 mole s-1
Alguien sabe como puedo saber si la bebida (gaseosa) al contener agua carbonatada, ¿esta pasa por electrolisi?, ya que el H2O, podria ser que puede ser de reaccion de sintesis, que seria H2+02------>H20? Seria hidrogeno gaseoso y pxigeno gaseoso formaria el agua carbonatada?, ayuda tengo esta duda >_
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.

Deforestation is the act of destroying forests so the land can be used for other purposes. Do you think deforestation increases, decreases, or has no effect on the biodiversity of the forest ecosystem? Explain your answer.
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.

What mass of potassium would need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C? (cpotassium = 0.753 J/g°C)
Answer:
Explanation:
q = mCΔT
m =CΔT/q
ΔT = 57.8°C - 44.3°C = 13.5°C
m = (0.753*13.5)/2350
m = 0.00433 g
The mass of potassium that will need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C is 231.17 g
Data obtained from the question Heat (Q) = 2350 JInitial temperature (T₁) = 44.3 °CFinal temperature of water (T₂) = 57.8 °CChange in temperature (ΔT) = 57.8 – 44.3 = 13.5 °C Specific heat capacity (C) = 0.753 J/gºC Mass (M) =?Q = MCΔT
2350 = M × 0.753 × 13.5
2350 = M × 10.1655
Divide both side by 10.1655
M = 2350 / 10.1655
M = 231.17 g

A solution has pH of 9 what is it?
Explain what will happen to the organisms that is affected by human activities.
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.

What volume would be occupied by 16.0 g of CH4 at 00C and 760 mmHg?
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

gamma < beta < alpha
beta < gamma < alpha
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.
