A cycle consists of a carefully balanced set of molecules. In order for the cycle to continue, this balance must be maintained. How many turns of the calvin cycle must occur before one molecule of g3p can leave?.

Answers

Answer 1

The Calvin cycle must occur before the molecule exits g3p is 3.

Three Calvin cycles are required to make the G3P molecule. This allows the G3P molecule to break out of the cycle and continue making glucose. All three requirements are required:

Chlorophyll pigments, chloroplast "theater" and enzyme catalysis. In the first stage, it converts light energy into chemical energy, which until then is stored in ATP and NADPH molecules.

In the second step of the Calvin Cycle, the carbon-fixed 3-PGA molecule is converted to the monosaccharide molecule glyceraldehyde-3-phosphate. This stage uses energy from ATP and NADPH produced in the light-dependent reactions of photosynthesis. The Calvin cycle harnesses the chemical energy of ATP and reduces the power of NADPH from a light-dependent reaction to produce tricarbonate.

The visible spectrum for a colored solution has a maximum absorbance around 500 nm and a maximum % transmittance around 640 nm. What is the color of the solution?.

Answers

The colour of the solution is Green.

How does spectroscopy work?

The science of spectroscopy involves analyzing electromagnetic spectra as a function of the wavelength or frequency of the radiation that are produced when electromagnetic radiation interacts with materials.

Lower wavelengths in the visible spectrum, which has a wavelength range between 400 and 700 nm, are equivalent to the violet side of the rainbow spectrum, while higher wavelengths are equivalent to the red side. The violet and red portions of the spectrum should be absorbed by our solution and not be visible because our solution absorbs heavily at about 440 and 600 nm. Green should consequently be the hue that can be seen from the solution because it has the lowest absorption at about 520 nm.

Green is absorbed at a wavelength of 500 nm. This indicates that it will absorb green and display red, which is red's complementary colour.

This is an allusion to spectroscopic techniques that calculate the amount of radiation absorbed in relation to frequency or wavelength when it interacts with an object. For absorption spectroscopy, the complete electromagnetic spectrum is utilized.

Answers

change in entropy for CO2 is 83.78 J/[tex]^{o}C[/tex] and for N2 is 121 J/[tex]^{o}C[/tex]

Entropy Change can be defined as the change in the state of disorder or randomness of a thermodynamic system that is associated with the conversion of heat or enthalpy into work. A system with a great degree of disorderliness or randomness has more entropy.

Entropy also describes how much energy is not available to do work. The more disordered a system is higher is the entropy, the less of a system's energy is available to do work.

To calculate the change in entropy;

For CO2:

Moles of CO2 = [tex]10^{5}[/tex] × 0.7 ÷ (R×298) = 234.9/R

ΔS = 234.9 ln (1/0.7) = 83.78

For N2;

Moles of N2 = [tex]10^{5}[/tex] × 0.3 ÷ (R×298) = 100.7/R

An atom has 29 protons, 30 neutrons, and 27 electrons. What is the mass number?

Answers

The atomic number of copper is 29, and it has the mass number 63. The number of protons in the nucleus determines the atomic number, and the number of protons and neutrons determines the mass number.

What is the mass number?

The total number of protons and neutrons in an atomic nucleus is known as the mass number, sometimes known as the atomic mass number or nucleon number. It is roughly equivalent to the atom's atomic mass expressed in an atomic mass unit.

It is calculated by adding the total amount of protons and neutrons. For instance, the atomic number of magnesium is 4, while the atomic number of lithium is 4, which is equal to the number of protons. Eight ( 4 + 4 ) is the mass number.

Because it indicates the mass of all the protons and neutrons in an element, the mass number of an element is designated as such. The atomic number and atomic mass of an element are often listed in periodic tables along with the chemical symbols for each element.

Type the correct answer in the box. Express the answer to two significant figures. Given: N2 + 3H2 → 2NH3 Use the bond energies to calculate the change in enthalpy for the reaction. The enthalpy change for the reaction is [ ]kilojoules.

Answers

By using the bond energies given (picture attached) the change in enthalpy for the reaction will be -78 KJ

Bond energy of N≡N = 942 KJ/mol

Bond energy of H-H = 432 KJ/mol

Bond energy of N-H = 386 KJ/mol

Enthalpy change of the reaction = ?

Enthalpy change is the amount of heat evolved or absorbed during a chemical process.

The balanced chemical equation for the given reaction

    N₂ + 3H₂  →  2NH₃

So,

    number of moles of N≡N bonds = 1

    number of moles of H-H bonds = 3

    number of moles of N-H bonds = 2(3) = 6

In the first step bond breakage occurs between N≡N and H-H, as bond breakage absorbed heat so we use the plus sign here. In the second step bond formation releases energy so we use the minus sign here.

Calculate the enthalpy of the reaction

    Enthalpy of reaction = (1 × BE of N≡N) + (3 × BE of H-H) - (6 × BE of N-H)

    BE = bond energy

Put the bond energy values

    Enthalphy of reaction = (1 × 942) KJ + (3 × 432) KJ - (6 × 386 ) KJ

    Enthalphy of reaction =  -78 KJ

Answers

The heat of fusion of water is B. 348 J when 20g ice is dropped into the water at 35°C.

The heat of fusion of water is the amount of heat required to melt one gram of ice at 0.00°C. Since the ice melted in this experiment, we know that the heat of fusion must be greater than or equal to the amount of heat lost by the ice.

The heat lost by the ice can be calculated using the following equation:

Q = mc∆T

where Q is the heat lost by the ice, m is the mass of the ice, c is the specific heat capacity of ice, and ∆T is the change in temperature.

Using the values from the experiment, we have:

Q = (20.0 grams)(2.09 J/g°C)(35.0°C - 18.1°C)
