What is continental drift?

The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were “drifting” across the Earth, occasionally crashing through oceans and into one another, in the early 20th century.

The seafloor spreading is the increase of seawater covering the land area. The spreading of seawater is decreasing the land area.

State your claim and use evidence to support it. For each piece of evidence you use, explain how the evidence supports your claim or refutes another claim. Remember to explain what happened at both the macro and molecular scales.

Answers

Answer: The liquid oxygen machine is producing less liquid oxygen than normal because there's a low attraction between the molecules.

It should be noted that oxygen in its liquid state will take up less space. It can also be stored at a lower pressure than when it's in its gaseous state.

A is Ea, which stands for activating energy. Energy is needed to get the reaction underway and Ea is the energy needed to “start” the reaction.

B is the temperature either released or absorbed.

The diagram shows that the reaction is exothermic based on the fact that the products energy is lower than the reactants. That is because energy (which is temperature in this case) is released during the process. If the reactants would have been lower than the products, the reaction would be endothermic.

Answer and explanation:

(c)

A represents the activation energy (the minimum amount of energy needed to start a reaction).

B represents the overall change in energy (the difference between the energy of the reactants and products).

(d)

The reaction profile diagram shows that the reaction is exothermic because the energy change is negative (the products have less energy than the reactants) which shows that energy is lost or given out to the surroundings.

(e)

HCl gas doesn't conduct electricity, but hydrochloric acid does because in HCl, there are hydrogen ions that are free to move so they can carry a charge.

There are roughly 720 billion metric tons of carbon in the atmosphere. An even bigger carbon sink is found in the oceans, which contain about 40 trillion metric tons. Human activities increase the amount of carbon stored in these reservoirs. The primary source of this increase is the combustion of fossil fuels, which generates about 6 billion metric tons of carbon per year. Deforestation adds an additional 2 billion metric tons annually. Whereas 25% of this flux ends up being absorbed by the oceans and another 25% is absorbed by plants, 50% stays in the atmosphere for the duration of its residence time. How much carbon will human activities add to the atmosphere over the course of five years

A production of 17.5 × 10⁹ tonnes of carbon will be added to the atmosphere over the course of five years.

How to determine the potential carbon generation due to human activities

In accordance with the principle of mass conservation, mass is not created nor destroyed, just transformed as we infer from statement.

The total carbon generation due to human activities is the sum of the effects derived from the combustion of fossil fuels and the deforestation, whose total over the course of five years is:

[tex]x = (5\,years)\cdot \left(6\times 10^{9}\,\frac{t}{yr} + 2\times 10^{9}\,\frac{t}{yr} \right)[/tex]

Answers

From the calculations performed, the Kb of the reaction is 9.9 * 10^-10

What is Kb?

The term Kb refers to the base dissociation constant of a solution. We have the following information from the question;

pH of the solution = 8.60

concentration of p-toluidine =  0.016-M

Recall that  pOH = 14 - pH

pOH = 14 - 8.60 = 5.4

[OH] = Antilog (-5.4) = 3.98 * 10^-6 M

We have to set up the ICE table;

          CH3C6H4NH2(aq) + H2O(l) ⇄ CH3C6H4NH3^+(aq) + OH^-(aq)

I             0.016                                           0                                   0

A mixture of 0.197 mol CO2 and 0.00278 mol H2O is held at 30.0 degrees celsius with a pressure of 2.50 atm. What is the partial pressure of each gas?

Answers

Considering the Dalton's partial pressure, the partial pressure of CO₂ is 2.465 atm and the partial pressure of H₂O is 0.035 atm.

Dalton's law

The pressure exerted by a particular gas in a mixture is known as its partial pressure.

So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

[tex]P_{T} =P_{1} +P_{2} +...+P_{n}[/tex]

where n is the amount of gases in the mixture.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.

So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

[tex]P_{A} =x_{A} P_{T}[/tex]

Partial pressure of CO₂ and H₂O

In this case, you know:

[tex]n_{CO_{2} }[/tex]= 0.197 moles[tex]n_{H_{2}O }[/tex]= 0.00278 moles[tex]n_{T }=n_{CO_{2} }+n_{H_{2}O }[/tex]= 0.197 moles + 0.00278 moles= 0.19978 moles[tex]P_{T}= 2.50 atm[/tex]

Then:

[tex]x_{CO_{2}} =\frac{n_{CO_{2}} }{n_{T} }=\frac{0.197 moles}{0.19978 moles} = 0.986[/tex][tex]x_{H_{2}O} =\frac{n_{H_{2}O} }{n_{T} }=\frac{0.00278 moles}{0.19978 moles} =0.014[/tex]

Replacing in the Dalton's law:

[tex]P_{CO_{2} } =x_{CO_{2}} P_{T}[/tex]

[tex]P_{CO_{2} } =[/tex] 0.986× 2.50 atm

[tex]P_{CO_{2} } =[/tex] 2.465 atm

[tex]P_{H_{2}O } =x_{H_{2}O} P_{T}[/tex]

[tex]P_{H_{2}O } =[/tex] 0.014× 2.50 atm

[tex]P_{H_{2}O } =[/tex] 0.035 atm

Finally, the partial pressure of CO₂ is 2.465 atm and the partial pressure of H₂O is 0.035 atm.

Explanation:

that’s the ones I put and I got a 100% on my test just now

The types of R groups that can exist in amino acids include acidic, non-polar, basic, and polar groups.

1. Acidic R groups: These groups have a negative charge and can donate a proton (H+). An example of an amino acid with an acidic R group is aspartic acid (Asp) or glutamic acid (Glu).

2. Non-polar R groups: These groups are hydrophobic and do not have a charge. They are composed mainly of carbon and hydrogen atoms. Examples of amino acids with non-polar R groups include alanine (Ala), valine (Val), and phenylalanine (Phe).

3. Basic R groups: These groups have a positive charge and can accept a proton. An example of an amino acid with a basic R group is lysine (Lys) or arginine (Arg).

4. Polar R groups: These groups are hydrophilic and have a partial charge. They can form hydrogen bonds with other polar molecules. Examples of amino acids with polar R groups include serine (Ser), threonine (Thr), and asparagine (Asn).

Thus, types of R groups that can exist in amino acids include acidic, non-polar, basic, and polar groups.
