Ecosystems are self-sustaining. They naturally recycle resources without human intervention. Do you think this is true for a pop- bottle biome?
Answer:
yes. For a pop bottle biome to be self sustaining it needs a water cycle, mineral cycle, solar energy flow, and a balance.

Answer:
I would say no because you have to add water and other recourses for it to grow and work
Explanation:
This molecule undergoes a substitution reaction through an SN1 pathway when warmed and stirred with HBr. Draw the two substitution products of this reaction. Show the correct stereochemistry by using wedges and dashes at all chiral centers. In part two, select the term that correctly describes the relationship between the products.
Answer:
See explanation and image attached
Explanation:
The mechanism of this reaction is shown in the image attached. The image was obtained from HomeworkLib.
The first step in the reaction is protonation and loss of -OH2. A carbocation is now created which undergoes a 1,2 hydride shift. This yields a tertiary carbocation which is more stable.
A racemic mixture of two products, major and minor are now obtained as shown.

What most likely happens when water loses heat?
It changes into ice.
It changes into vapor.
Its temperature increases.
Its temperature remains constant.
Answer:
It changes into ice.
Explanation:
solid form of water. When water vapor in the atmosphere cools down, it will condense and change back into liquid water, forming clouds
Answer:
It changes into ice,
Explanation:
Because if it's hot it would melt or evaporate, but if it's LOSING heat it would mean the opposite, and the only one that supports this is that "it changes into ice". Hope this helped, sorry i wasn't on for some time

When a system is at equilibrium, ________. When a system is at equilibrium, ________. the reverse process is spontaneous but the forward process is not the forward and the reverse processes are both spontaneous both forward and reverse processes have stopped the forward process is spontaneous but the reverse process is not the process is not spontaneous in either direction
Answer:
When a system is at equilibrium, the process is not spontaneous at either direction.
Explanation:
The process is not spontaneous at either direction , when a system is at equilibrium ΔG = 0, because -
We know that a negative ΔG indicates a forward-moving phase that is random.
We already know that a positive ΔG implies a non-spontaneous phase going forward.
Thus , here ΔG = 0, so the process is not spontaneous in either direction.

Ellie started her reaction between the KMnO4 and malonic acid by first heating the two solutions in the hot water bath. She then removed the test tubes from the water bath and poured the KMnO4 into the 75-mL test tube containing the malonic acid. She mixed the solution, placed it back into the water bath, then started the timer. For the data collected at 75 oC, indicate how the process explained above impacts the reaction time.a. The time recorded in the lab notebook is the true reaction time because the reaction only starts after the timer is started b. The time recorded in the lab notebook is longer than the true reaction time because the reaction starts the moment the two solutions were mixed c. The time recorded in the lab notebook is the true reaction time because the reaction only starts after the mixture is placed back into the hot water bath d. The time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed
Answer:
The time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed
Explanation:
A chemical reaction is "a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction" (Oxford dictionary).
A chemical reaction begins immediately the reactants are mixed together in a reaction vessel because the particles of the reactants immediately begin to collide with each other. There is no lost time before reactions begins!
This implies that, the time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed.

A flask with a volume of 1.50 L, provided with a stopcock, contains ethane gas 1C2H62 at 300 K and atmospheric pressure 11.013 * 105 Pa2. The molar mass of ethane is 30.1 g>mol. The system is warmed to a temperature of 550 K, with the stopcock open to the atmosphere. The stopcock is then closed, and the flask is cooled to its original temperature. (a) What is the final pressure of the ethane in the flask
Solution :
Apply ideal gas equation, PV=nRT to find the number of moles.
The number of moles of a gas is
[tex]$n=\frac{P_1V_1}{RT_1}$[/tex]
[tex]$n=\frac{(11.013 \times 10^5\ Pa)(1.50 \times 10^{-3}\ m^3)}{(8.134 \ J/Mole.K)(300 \ K)}$[/tex]
n = 0.66 mole
The initial mass of the ethane in the flask is
m = 0.66 mole x 30.1 g/mole
= 19.866 g
The volume and the number of moles remains constant after the stopcock is closed.
The final pressure of the ethane is
[tex]$p_2=\frac{T_2}{T_1}p_1$[/tex]
[tex]$=\frac{300}{550} \times 11.013 \times 10^5$[/tex]
= [tex]$60.0709 \times 10^4 \ Pa$[/tex]

Explanation:
when you are doing something (working) you are using up your energy
Question
Does _____ energy.
When you do work on an object, some of your energy is transferred to the object. You can think of work as the transfer of energy. In fact, both work and energy are measured in the same unit, the joule. ... Energy can be transferred from the man to the ball, but the total amount of energy in the system does not change.
Therefore, the answer is ( C ).

calculate the value of the equilibrium constant Kp for this reaction. Round your answer to 2 significant figures.
Kp=
Answer: The value of the equilibrium constant Kp for this reaction is [tex]3.3\times 10^3[/tex]
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K
For the given balanced chemical reaction:
[tex]4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)[/tex]
The expression for [tex]K_p[/tex] is written as:
[tex]K_p=\frac{[p_{NO}]^4\times [p_{H_2O}]^6}{[p_{NH_3}]^4\times [p_{O_2}]^5}[/tex]
[tex]K_p=\frac{(12.1)^4\times (65.8)^6}{(65.3)^4\times (7.79)^5}[/tex]
[tex]K_p=3.3\times 10^3[/tex]
The value of the equilibrium constant Kp for this reaction is [tex]3.3\times 10^3[/tex]

What is the pressure (in atm) in a 5.00 L tank with 9.00 grams of oxygen gas at 350 K?
Answer:
1.61 atm
Explanation:
Using general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
From the information provided in this question,
V = 5.00L
T = 350K
mass of O2 = 9.00g
Using mole = mass/molar mass
Molar mass of O2 = 16(2) = 32g/mol
mole = 9/32
mole = 0.28mol
Using PV = nRT
P = nRT/V
P = 0.28 × 0.0821 × 350/5
P = 8.0458/5
P = 1.609
Pressure = 1.61 atm
The pressure of the oxygen gas at the given temperature and volume is 1.61 atm.
The given parameters;
volume of the gas, V = 5 Lmass of the oxygen gas, m = 9 gtemperature of the gas, T = 350 KThe number of the moles of the given gas is calculated as follows;
[tex]moles = \frac{m}{M} \\\\moles = \frac{9}{32} \\\\moles = 0.28 \ mol[/tex]
The pressure of the gas is calculated as follows;
[tex]PV = nRT\\\\P = \frac{nRT}{V} \\\\P = \frac{0.28 \times 0.0821 \times 350}{5} \\\\P = 1.61 \ atm[/tex]
Thus, the pressure of the oxygen gas at the given temperature and volume is 1.61 atm.
