What's photosynthesis?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

An unknown element is a mixture of isotopes ¹²⁹X and ¹³²X. The average atomic mass of X is 131.01 amu. What is the percent abundance of ¹³²X?

Answers

 Answer:    67%

Explanation:  The weighted averages of the two isotopes must add to 131.01.  Let Y be the percentage of isotope 129.  Then (1-Y) will be the percentage of isotope 132.  The weighted average of each is:

129:   129Y

132:    132(1-Y)

Their sum is equal to 131.01

129Y + 132(1-Y) = 131.01

Y = 0.33, or 33%

(1-Y) = 0.67, or 67%

Check:  129*(0.33) = 42.57

             132*(0.67) = 88.44

                     Sum =   131.01  It checks OK  The 132 isotopes is 67% of the sample.

Considering the definition of atomic mass, isotopes and atomic mass of an element, the percent abundance of ¹³²X is 67%.

Definition of atomic mass

First of all, the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus of a chemical element.

Definition of isotope

The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element.

Definition of atomic mass

On the other hand, the atomic mass of an element is the weighted average mass of its natural isotopes. In other words, the atomic masses of chemical elements are usually calculated as the weighted average of the masses of the different isotopes of each element, taking into account the relative abundance of each of them.

Percent abundance of ¹³²X

In this case, you know:

An isotope has an atomic mass of 132 amu and a percent natural abundance of y.An isotope has an atomic mass of 129 amu and a percent natural abundance of 1-y. The average atomic mass of X is 131.01 amu

Then, the average mass of X can be calculated as:

132 amu×y + 129 amu×( 1-y)= 131.01 amu

Solving, you can find the percent abundance of ¹³²X:

132 amu×y + 129 amu×1 - 129 amu×y= 131.01 amu

132 amu×y + 129 amu - 129 amu×y= 131.01 amu

132 amu×y - 129 amu×y= 131.01 amu - 129 amu

3 amu×y= 2.01 amu

y= 2.01 amu÷ 3 amu

y= 0.67= 67%

Finally, the percent abundance of ¹³²X is 67%.

Answer:

The last option is the correct answer.

Explanation:

When an element is oxidized, it loses electrons. But when an element is reduced, it gains electrons. This is the basis of redox reactions.

However, an oxidizing agent oxidizes something else, and gets reduced, therefore gaining electrons. Meanwhile, a reducing agent reduces something else, and gets oxidized in the process, losing its own electrons.

a sample of gas is originally at 12°C is heated so it's total kinetic energy doubles . what is the new temperature of the sample​

Answers

wE know

[tex]\boxed{\sf E\propto T}[/tex]

Hence If Kinetic energy is doubled Temperature will also be doubled.

[tex]\\ \sf\longmapsto T=12(2)=24°C[/tex]

The kinetic energy is directly proportional to the temperature. Hence, as kinetic energy doubles, the temperature become  approximately 297.15°C.

What is kinetic energy ?

Kinetic energy is the energy generated by virtue of the motion of the substance.

Assuming the pressure and volume of the gas sample are constant, the temperature of an ideal gas is directly proportional to its average kinetic energy. When the total kinetic energy of the gas doubles, its temperature will also double.

To calculate the new temperature of the sample, we can use the following equation:

(T2/T1) = (E2/E1)

where T1 is the initial temperature, E1 is the initial total kinetic energy, T2 is the final temperature, and E2 is the final total kinetic energy.

Since the total kinetic energy has doubled, E2 = 2E1. Substituting this into the equation, we get:

(T2/T1) = 2

Multiplying both sides by T1, we get:

T2 = 2T1

Substituting the initial temperature T1 = 12°C + 273.15 K = 285.15 K, we get:

T2 = 2 x 285.15 K = 570.3 K

Converting the final temperature from Kelvin to Celsius, we get:

T2 = 570.3 K - 273.15 = 297.15°C

Therefore, the new temperature of the gas sample is approximately 297.15°C.

Select the arrangement that orders the compounds by increasing boiling point based on predominant intermolecular force. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices N2 < CO2 < NH3 < HF

Answers

The arrangement that orders the compounds by increasing boiling point based on predominant intermolecular force is; N2 < CO2 < NH3 < HF

The molecules that compose a substance are held together by intermolecular forces. The physical properties of a substance such as boiling points depends on the nature of intermolecular forces between substances. The greater the magnitude of intermolecular interaction between bonding atoms the higher the boiling point.

Nitrogen and CO2 molecules are only held together by weak dispersion forces.  However, CO2 has a higher boiling point than N2 because CO2 has a higher molecular mass than N2.

Nitrogen is less electronegative than fluorine hence the magnitude intermolecular interaction via hydrogen bonding in HF is greater than that in NH3 consequently, the boiling point of HF is higher than that of NH3.

A pycnometer is a glass apparatus used for accurately determining the density of a liquid. When dry and empty, a certain pycnometer had a mass of 27.056 g. When filled with distilled water at 25.0°C, it weighed 36.773 g. When filled with chloroform (a liquid once used as an anesthetic before its toxic properties were known), the apparatus weighed 41.451 g. At 25.0°C, the density of water is 0.99704 g/mL

-What is the volume of the pycnometer (mL)

 

We have that the volume of the pycnometer in mL is

[tex]V=9.111mL[/tex]

From the Question we are told that

Pycnometer mass of [tex]m_p=27.056 g.[/tex]

Temperature [tex]T=25 \textdegree[/tex]

Pycnometer filled with distilled water [tex]m_{pf}= 36.773 g[/tex]

Apparatus weighed [tex]w=41.451 g[/tex]

Density of water [tex]\rho= 0.99704 g/mL[/tex]

Generally the equation for Density  is mathematically given as

[tex]\rho=\frac{mass}{Volume}[/tex]

Since pycnometer is filled with water its volume can be defined by the volume of water in it

Therefore

A cylinder fitted with a movable piston and filled with a gas has a volume of 188.5mL at 26.7 °C when the applied pressure is 755.2 torr. The temperature of the oil bath surrounding the cylinder was increased to 165.2 °C, and the load on the piston was changed. Careful measurement now gave a value of 210.5mL for the volume. What was the final pressure in the system, in torr? Select one:
O a. 715.5 tor O b. 576.9 torr Oc. 988 6 torr O d. 1233 torr 462.6 tor

Answers

Answer:

C

Explanation:

To find the new pressure, we will use this formula: P₁V₁/T₁ = P₂V₂/T₂

P₁ = Original pressure (755.2)

V₁ = Original volume (188.5)

T₁ = Original temperature in kelvins (26.7 + 273.15 = 299.85)

P₂ = Final Volume (?)

V₂ = Final volume (210.5)

T₂ = Final temperature in kelvins (165.2 + 273.15 = 438.35)

Here is our equation

(755.2)(188.5)/(299.85) = (210.5)P₂/(438.35)

Hopefully, you have a calculator handy because this equation will end up looking like this:

474.75471 = (0.48021)P₂

Divide both sides by the coefficient

474.75471/0.48021 = (0.48021)P₂/0.48021

P₂ = 988.64
