2. What evidence is there that mass extinction events occurred?
Answer: Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. Examples, of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.

Chlorine has two stable isotopes, C1 and C If Cl has a mass of approximately 34.97 and Cl has a mass of approximately 3697 what percent abundances are each found in?
Answer:
%C₁ = %C₂ = 50%
Explanation:
Set up simultaneous equations to solve for two unknowns,
let f₁ and f₂ = fractional abundances of C₁ and C₂ respectively.
Then f₁ + f₂ = 1.00 and
34.97f₁ + 36.97f₂ = Wt. Avg. Atomic Mass (amu) = (34.97 + 36.97)/2 = 35.97amu
Solve equation 1 for f₂ = 1 - f₁ and substitute into equation 2
=> 34.97f₁ + 36.97(1 - f₁) = 35.97
=> 34.97f₁ + 36.97 - 36.97f₁ = 35.97
=> 2f₁ = 1
=> f₁ = 1/2 = 0.50 => 50% abundance for C₁
=> f₂ = 1 - 0.50 = 0.50 => 50% abundance for C₂

1) The ionic compound below is soluble in water. Complete the following:
-Draw the interaction of the ionic compound and water in the proper orientation. 3pts
-On the line below discuss the strength of the interaction within the compound compared to the strength of interaction
between the compound and water.
Answer:
The hydrogens of the water molecules around the bromide ion will need to be faced toward it, whereas the oxygens of the water molecules around the potassium ion will need to be faced toward it.
The strength of the interaction within the compound will supersede that of the interaction between the compound and water.
Explanation:
To answer this question, you need to be aware of the structure of a water molecule and its components. A water molecule has the chemical formula of H2O, and oxygen is inherently electronegative, meaning that it attracts electrons very strongly. As a result, when it is in H2O, it pulls the valence electrons of the H atoms very strongly, which results in the H atoms being partially positively charged and the O atom being partially negatively charged. Therefore, the O atom is going to be attracted to the potassium ion, whereas the H atom is going to be attracted to the bromide ion.
The answer to the second part of the question is as written above because ionic bonds are stronger than ion-dipole bonds; that's just the way it is.

Why do you think it is a bad idea to use taste, touch, or smell to identify an
unknown chemical?
Answer:
Because it can cause health problems or injuries to our sense organs.
Explanation:
Chemicals in the laboratory are made up of different constituents, which may be dangerous or injurious to health. This is the reason why safety measures or precautions have to be taken when working in the laboratory. One of those safety measures is that "one should never use taste, touch, or smell to identify an unknown chemical".
This is so because a chemical that is unknown amounts to the fact that what such chemical contains is unknown, hence, the chemical might have the ability to cause harm or injuries to the sense organ. For example, a conc. acid that is tasted will burn the tongue etc.

4.2 L of a gas has a pressure of 560mmHg at 72⁰F. What is the temperature at760mmHg if the volume is still 4.2 L? (5 pts)
Answer:
The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K
Explanation:
Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:
[tex]\frac{P}{T} =k[/tex]
Having an initial state 1 and a final state 2, the following is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 560 mmHgT1= 72 F= 295.372 K (being 32 F= 273.15 K)P2= 760 mmHgT2= ?Replacing:
[tex]\frac{560 mmHg}{295.372 K} =\frac{760 mmHg}{T2}[/tex]
Solving:
[tex]T2= 760 mmHg*\frac{295.372 K}{560 mmHg}[/tex]
T2= 400.862 K

Identify at least three control variables that could be used with this investigation: What temperature allows for bacterial growth to occur quickly?
Answer:
Time allowed for incubation, size of the dish, the amount of light, amount of agar, the type of agar…etc
Explanation:
We define a control variable as any variable that has to be held constant during a study.
If i wish to study what temperature allows for bacterial growth to occur quickly, i will have to subject different bacterial cultures to different temperatures.
The variables that must remain the same across all these cultures at different temperatures is what we call the control variables. They ensure that the results of the study are reliable.

How many liters of hydrogen gas is produced at 298 K and 0.940 atm if 4.00 moles of hydrochloric acid react with an excess of magnesium metal?
O 26.0 liters
O 52.1 liters
82.3 liters
104 liters
Answer:
74.04 liters of hydrogen gas are produced.
Explanation: According to reaction, 2 mol of HCl gas gives 1 mole of hydrogen gas, then 6 moles of HCl gas will give: moles of hydrogen gas that is 3 moles.
The pressure of the hydrogen gas at 298 K = 0.990 atm
The volume occupied by the hydrogen gas = V
Number of hydrogen has moles = 3 moles
PV=nRT
V = 74.04 L
74.04 liters of hydrogen gas are produced.
Answer:
38.2 liters Is the answer
