Bears stop coming to a river ecosystem where they have been eating many fish each day. The fish the bears eat normally eat smaller fish, which eat plants along the river bottom.
What happens to the ecosystem?
Both the larger and the smaller fish populations grow quickly but then die out because the plant life is insufficient for them all to eat.
The larger fish population will drop first, and the smaller fish population will grow quickly. The plants will die off because too many of the smaller fish are eating them.
The larger fish population explodes at first, and the smaller fish population begins to drop. Eventually, the river runs out of smaller fish so larger fish die out, and the plant population grows.
The smaller fish population begins to eat more plants and to grow. The larger fish have more food to eat so their population is able to grow, too.
Answer:
The larger fish population explodes at first, and the smaller fish population begins to drop. Eventually, the river runs out of smaller fish so larger fish die out, and the plant population grows.
Explanation:
During the workup portion of the reaction of alkenes with HBr as described in the experiment provided, a student transferred the reaction mixture to a separatory funnel, rinsed the reaction flask with diethyl ether, and added the ether rinses to the separatory funnel. The student then added sodium bicarbonate to the separatory funnel. Extremely vigorous bubbling occurred. What did the student do wrong
Answer:
Explanation:
Because of the acid-base reaction, as sodium bicarbonate is introduced to the separatory funnel, the additional or unreacted HBr reacts vigorously to yield CO2 gas, which exits the separatory funnel together with any dissolved compound(s) in the ether layer. This is due to a wrong and incorrect selection of the solvent mixture and the addition of sodium bicarbonate to an acidic solution.
Nothing to do with it until it has leaked out of the separatory funnel. Even then, the student may separate the components from the remaining reaction mixture by washing the ether coating layer several times with brine water, then running it into a dry sodium sulfate bed and evaporating solvent ether under decreased pressure.

Answer:
12.7mol Na.
Explanation:
Hello there!
In this case, according to the concept of mole, which stands for the amount of substance, we can recall the concept of Avogadro's number whereby we understand that one mole of any substance contains 6.022x10²³ particles, for the given atoms of sodium, we can calculate the moles as shown below:
[tex]7.9x10^{23}atoms*\frac{1mol}{6.022x10^{23}atoms} \\\\[/tex]
Thus, by performing the division we obtain:

The solution you identified in question (1) acts as a buffer due to reactions that occur within the solution when an acid or a base is added. Write the net ionic chemical equation for the reaction that occurs within this buffer solution when HCl(aq) is added. (Phase labels should be included in all net ionic chemical equations.)
Answer:
The answer is "[tex]\bold{CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)}[/tex]"
Explanation:
When [tex]HCI[/tex] is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
[tex]CH_3COONa\ (aq) + HCl\ (aq)\longrightarrow CH_3COOH\ (aq) + NaCl\ (aq)\\\\[/tex]
In this, the [tex]CH_3COOH[/tex] is a weak acid so, it not completely dissociated.
[tex]CH_3COONa \ (aq) \ \ and \ NaCl[/tex] were strong electrolytes they are completely dissociated.
The [tex]HCl[/tex] is a strong acid so, it is completely dissociated So, the net ionic equation is:
[tex]CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)[/tex]

3.8 moles of X2Y5Z3 is equivalent to how many grams?
Enter your answer to zero decimal places (round to the ones place). Do
not include the units of "g", just the numerical answer.
Answer:
2663 g
Explanation:
We'll begin by calculating the molar mass Of X₂Y₅Z₃. This can be obtained as follow:
Molar mass of X₂Y₅Z₃ = (13.25×2) + (69.23×5) + (109.34×3)
= 26.5 + 346.15 + 328.02
= 700.67 g/mol
Finally, we shall determine the mass of 3.8 moles of X₂Y₅Z₃. This can be obtained as follow:
Molar mass of X₂Y₅Z₃ = 700.67 g/mol
Mole of X₂Y₅Z₃ = 3.8 moles
Mass of X₂Y₅Z₃ =?
Mass = mole × molar mass
Mass of X₂Y₅Z₃ = 3.8 × 700.67
Mass of X₂Y₅Z₃ = 2663 g
Therefore, the of 3.8 moles of X₂Y₅Z₃ is
2663 g

Final volume of a .50 M H3PO4 solution prepared from 50 mL of a 6 M H3PO4 solution
Answer:
600 mL
Explanation:
From the question given above, the following data were obtained:
Initial concentration (C₁) = 6 M
Initial volume (V₁) = 50 mL
Final concentration (C₂) = 0.5 M
Final volume (V₂) =?
Using the dilution formula (i.e C₁V₁ = C₂V₂) we can obtain the final volume as illustrated below:
C₁V₁ = C₂V₂
6 × 50 = 0.5 × V₂
300 = 0.5 × V₂
Divide both side by 0.5
V₂ = 300 / 0.5
V₂ = 600 mL
Thus, the final volume is 600 mL
How do conduction, convection, and radiation redistribute incoming solar energy?
The solar energy from sun is radiating to the earth's surface and making the atmosphere warmer. The heat energy is redistributing back by through different heat transfer modes.
What is heat transfer?Heat energy transfer from hotter region to colder region by the temperature gradient. The heat is transferring through solids by conduction. Conduction is the process of heat transfer through the closely packed particles in solids.
Heat transfers through convection in liquids. Where the hot molecules rise to the surface and transfers the heat to other molecules. The heat radiated to the earth make the sources in earth warmer. Through convection, the water molecules heat up.
The water vapor formed by convection process radiates to the atmosphere and redistributes the energy back.

Which statement about nuclear fission and nuclear fusion is not correct?
A. Both processes change atoms of one element to another element.
B. Both processes can release huge amounts of energy.
C. Both processes conserve mass.
D. Both processes produce dangerous radiation.
The statement, that describes about nuclear fission and nuclear fusion is "both processes can release huge amounts of energy."
What is nuclear fission and fusion?Nuclear fission is the process by which an atom's nucleus breaks into two or more smaller nuclei. Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process.
Fusion and fission are both nuclear reactions that yield significant amounts of energy that can be used to generate power. However, fission is the splitting of atoms, whereas fusion is the joining of them.
To put in another way, while both nuclear reactions that generate energy, the methods are vastly different. They both produce a lot of energy.
Hence the correct answer is B.

How many grams are there in 1.8055 x 10^25 molecules of sodium sulfate? Hint: Convert to moles first
Answer:
4258.82 g of Na₂SO₄
Explanation:
From the question given above, the following data were obtained;
Number of molecules of Na₂SO₄ = 1.8055x10²⁵ molecules.
Number of mole of Na₂SO₄ =?
From Avogadro's hypothesis,
6.02×10²³ molecules = 1 mole
Therefore,
6.02×10²³ molecules = 1 mole of Na₂SO₄
Next, we shall determine the mass of 1 mole of Na₂SO₄. This can be obtained as follow:
1 mole of Na₂SO₄ = (23×2) + 32 + (16×4)
= 46 + 32 + 64
= 142 g
Thus,
6.02×10²³ molecules = 142 g of Na₂SO₄
Finally, we shall determine the mass of Na₂SO₄ that contains 1.8055x10²⁵ molecules. This can be obtained as follow:
6.02×10²³ molecules = 142 g of Na₂SO₄
Therefore,
1.8055x10²⁵ molecules
= (1.8055x10²⁵ × 142) / 6.02×10²³
= 4258.82 g of Na₂SO₄
Thus, 4258.82 g of Na₂SO₄ contains 1.8055x10²⁵ molecules

A 27.5g piece of aluminum sits in a room and cools. It loses 6120.0 J of heat. If the initial
temperature of aluminum is 157.3°C, what is the final temperature? The specific heat
capacity of aluminum is 0.900 J/gºC.
Answer:
[tex]T_2= -90.0°C[/tex]
Explanation:
Hello!
In this case, according to the given description of how the temperature changes for aluminum in agreement to the loss of heat of 6120.0 J, we can use the following equation:
[tex]Q=mC\Delta T=mC(T_2-T_1)\\\\[/tex]
Thus, by knowing Q, m, C and the initial temperature, we are able to obtain:
[tex]T_2=T_1+\frac{Q}{mC}\\\\T_2=157.3\°C+\frac{-6120.0J}{27.5g*0.900 J/g\ºC}\\\\T_2= -90.0°C[/tex]
