Scientists have observed that the average surface temperature of the Earth has been increasing. This increase has
affected the oceans. Glaciers and ice sheets melt, and water from this melting process becomes part of the oceans.
The increasing temperature of the Earth's surface also warms ocean waters. As a result, the volume of the oceans
expands. These two events affect sea level.
What would happen to sea level if the average surface temperature trend that was observed since the 1960s
continues?
A) Sea level will rise, then will suddenly fall.
B) Sea level will remain the same.
C) Sea level will continue to fall.

Image result for Molecules are chemically bonded atoms that work as a unit. Should the same kind of molecule be made up of the same kind of elements? Explain your answer

If this interaction is such that the total energy of the system is lowered, then the atoms bond together to form a molecule. Thus, from a structural point of view, a molecule consists of an aggregation of atoms held together by valence forces. Diatomic molecules contain two atoms that are chemically bonded.

How many joules are required to eat 5.25 g of titanium from 85.5 celsius to 132.5 celsius

Answers

The amount of energy required to eat 5.25 g of Titanium from 85.5 celsius to 132.5 celsius is 129 joules.

How do we calculate required heat?

Absorbed or released amount of heat will be calculated by using the below formula as:

Q = mcΔT, where

m = mass of titanium = 5.25g

c = specific heat of titanium = 0.523 J/gram degree celsius

ΔT = change in temperature = 132.5 - 85.5 = 47 degree celsius

On putting these values on the above equation we get,

Q = (5.25)(0.523)(47) = 129 joules

Hence required heat is 129 joules.

Given that the molar mass of naoh is 40.00 g/mol, what mass of naoh is needed to make 2.500 l of a 2.000 m naoh solution? use molarity equals startfraction moles of solute over liters of solution endfraction.. 0.1250 g 5.000 g 32.00 g 200.0 g

Answers

The mass of Sodium hydroxide which is needed to make 2.500 L of a 2.000 M NaOH solution is 200 grams.

How do we calculate mass from moles?

Mass of any substance will be calculated by using their moles as:

n = W/M, where

W = required mass

M = molar mass

Given that, molarity of NaOH = 2M

Volume of NaOH solution = 2.5L

Moles of NaOH will be calculated by using the below equation as:

M = n/V

n = (2)(2.5) = 5 moles

Now we calculate the mass of NaOH of 5 moles as:

W = (5mol)(40g/mol) = 200g

Hence option (4) is correct.

Calculate the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL.

Answers

Considering the definition of dilution, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.

What is diluion

First of all, you have to know that when it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volume

Molarity of the solution in this case

In this case, you know:

Ci= 4 M Vi= 7 mLCf= ?Vf= 30 mL

Replacing in the definition of dilution:

4 M× 7 mL= Cf× 30 mL

Solving:

(4 M× 7 mL)÷ 30 mL= Cf

Cf= 0.93 mL

In summary, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.

Hydrogen bonds are a special type of dipole-dipole attraction that results when hydrogen is bonded to one of the three most electronegative elements: F, O, or N.

The type of intermolecular force relates to the big difference in the electronegativities and is known as hydrogen bonding.

What are intermolecular forces?

Intermolecular forces may be defined as the mechanism that mediates the interaction between the atoms of the molecules. It significantly includes the electromagnetic forces of attraction and repulsion between the atoms.

Some examples of intermolecular forces include London-dispersion force, dipole-dipole interaction, van der Waals interaction, hydrogen bonds, etc. Each one of them possesses a different set of characteristic properties distinctly. Some types of forces are also present in the body of living organisms.

Hydrogen bonding is a characteristic kind of interaction that remarkably includes dipole-dipole attraction between the most electronegative elements like Nitrogen, Oxygen, fluorine, etc., and the hydrogen atom.

PLEASE HELP!!!! WILL MARK BRAINLIEST!!!! A rigid steel container with a volume of 30 L is filled with oxygen to a pressure of 9.00 atm at 28.0 °C. What is the pressure in the container if the temperature is raised to 129.0 °C?

Answers

Answer:

12 atm

Explanation:

First, let us convert Celcius into Kelvin: 28.0 °C = 301.15 K and 129.0 °C = 402.15 K

For this question we must employ the Combined Gas Law: [tex]\frac{P_1V_1}{P_2V_2}=\frac{n_1RT_1}{n_2RT_2}[/tex], where [tex]P_1[/tex] is the initial pressure and [tex]P_2[/tex] is the new pressure.

We know that intitially, P=9 atm, V=30 L, and T=301.15K. From our problem, only temperature and pressure changes, while the number of moles, volume and the gas constant, R, stay the same, so they are irrelevant.

Thus, the filled out Combined Gas Law would be:

[tex]\frac{9 atm}{P_2}[/tex]=[tex]\frac{301.15K}{402.15K}[/tex], where the volume, moles of gas, and R are cancelled out.

We can manipulate this equation to derive the new pressure. We find that

9atm≈0.74885[tex]P_2[/tex].

This means that

[tex]P_2[/tex]≈9/0.74885≈12 atm

What is the molar mass of a 3.228 g sample of a gas if it occupies 3.21 L at 298 K and 1.25 atm?

Answers

Taking into account the ideal gas law and the definition of molar mass, the molar mass of a 3.228 g sample of a gas if it occupies 3.21 L at 298 K and 1.25 atm is 19.66 [tex]\frac{g}{moles}[/tex].

What is ideal gas law

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:

P×V = n×R×T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

Number of moles in this case

In this case, you know:

P= 1.25 atmV= 3.21 Ln= ?R= 0.082 [tex]\frac{atmL}{mol K}[/tex]T= 298 K

Replacing in the ideal gas law:

1.25 atm× 3.21 L = n× 0.082 [tex]\frac{atmL}{mol K}[/tex]× 298 K

Solving:

n= (1.25 atm× 3.21 L)÷ (0.082 [tex]\frac{atmL}{mol K}[/tex]× 298 K)

n= 0.1642 moles

So, the number of moles in this case are 0.1642 moles.

Molar mass of the sample

In this case, you know:

mass= 3.228 gnumber of moles= 0.1642 moles

Then, considering the definition of molar mass, it is calculated as:

[tex]molar mass=\frac{3.228 g}{0.1642 moles}[/tex]

Solving:

molar mass= 19.66[tex]\frac{g}{moles}[/tex]

Finally, the molar mass of a 3.228 g sample of a gas if it occupies 3.21 L at 298 K and 1.25 atm is 19.66 [tex]\frac{g}{moles}[/tex].
