The molecule that can easily be formed from carbon dioxide and serve as a one-carbon donor while also doubling as a biological buffer is bicarbonate (E).
Bicarbonate (HCO3-) can accept a proton (H+) to become the weak acid carbonic acid (H2CO3), which can then dissociate into water and carbon dioxide (CO2).
Bicarbonate is an important component of the carbon dioxide-bicarbonate buffer system, which helps to maintain the pH of biological fluids.
Additionally, one-carbon groups can be transferred to tetrahydrofolate (THF) to form various intermediates in pathways such as nucleotide biosynthesis and amino acid metabolism.

How does a sugar solution become rock candy?
Answer:
Explanation:
A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
Dona is attempting to make an electromagnetic to pick up old nails in her driveway. Which of these materials would be best to us for the core to make the strongest electromagnetic to pick up the most nails?
Answer:
The materials would be best to us for the core to make the strongest electromagnetic to pick up the most nails is described below in detail.
Explanation:
Use a couple of wire strip-pers to exclude some centimeters of insulation from every end of the cable. Skillfully cover the cable around the nail. The more cable you enclose around the nail, the more effective your electromagnet will be. Compose certain that you leave sufficient of the cable unwrapped so that you can connect the battery.

mass-mass problem:
If 25.0 grams of carbon dioxide are used in photosynthesis how many grams of glucose (C6H12O6) could be Produced according
to the following equation : 6CO2 + 6H2O → C6H12O6 + 602
Answer:
17.05 g of glucose
Explanation:
The equation of the reaction is given as;
6CO2 + 6H2O → C6H12O6 + 602
From the equation;
6 mol of CO2 produces 1 mol of C6H12O6
Converting to masses;
CO2:
Mass =Number of moles * Molar mass
Mass = 6 mol * 44 g/mol = 264 g
C6H12O6:
Mass = Number of moles * Molar mass
Mass = 1 mol * 180 g/mol = 180 g
This means 264g of CO2 produces 180g of C6H12O6
25g of CO2 would produce x g of C6H12O6
264 = 180
25 = x
x = 25 * 180 / 264
x = 17.05 g

gas?
a 25.1L
b 39.2 L
С
12.8 L
d 15.7 L
Answer:
C. 12.8 liters.
Explanation:
The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains [tex]6.022 \times 10^{23}[/tex] molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:
[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)
[tex]P\cdot V = \frac{r\cdot R_{u}\cdot T}{N_{A}}[/tex] (1b)
Where:
[tex]P[/tex] - Pressure, measured in pascals.
[tex]V[/tex] - Volume, measured in liters.
[tex]r[/tex] - Amount of molecules, no unit.
[tex]N_{A}[/tex] - Avogadro's number, no unit.
[tex]R_{u}[/tex] - Ideal gas constant, measured in pascal-liters per mole-Kelvin.
[tex]T[/tex] - Temperature, measured in Kelvin.
If we know that [tex]P = 100000\,Pa[/tex], [tex]r = 3.44\times 10^{23}[/tex], [tex]N_{A} = 6.022\times 10^{23}[/tex], [tex]T = 273.15\,K[/tex] and [tex]R_{u} = 8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K}[/tex], then the volume of carbon dioxide at STP is:
[tex]V = \frac{r\cdot R_{u}\cdot T}{N_{A}\cdot P}[/tex]
[tex]V = \frac{(3.44\times 10^{23})\cdot \left(8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K} \right)\cdot (273.15\,K)}{(6.022\times 10^{23})\cdot (100000\,Pa)}[/tex]
[tex]V = 12.972\,L[/tex]
Therefore, the correct answer is C.

Given: C2H5C1
P1: 951.72 kPa
P2: 362.29 kPa
T1: 653.34 K
Wanted: kelvins?
Answer: The final temperature is 248.7 K
Explanation:
To calculate the final temperature of the system, we use the equation given by Gay lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.
Mathematically,
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
where,
[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.
[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.
We are given:
[tex]P_1=951.72kPa\\T_1=653.34K\\P_2=362.29kPa\\T_2=?[/tex]
Putting values in above equation, we get:
[tex]\frac{951.72}{653.34}=\frac{362.29}{T_2}\\\\T_2=248.7K[/tex]
Thus the final temperature is 248.7 K

After the shuttle disaster, an unknown compound residue was removed from a piece of the debris. Upon analysis, it was found to contain 2.61 g of carbon, 6.09 g of nitrogen, and 1.31 g of hydrogen. What is its empirical formula?
Answer:
The final empirical formula is [tex]C_2 N_5 H[/tex]
Explanation:
Given
The amount of carbon, nitrogen and hydrogen in a given compound is as follows
C:N:H
[tex]2.61 : 6.09 : 1.31[/tex]
On simplifying the ration values we get
[tex]\frac{2.61}{1.31} : \frac{6.09}{1.31} : \frac{1.31}{1.31}[/tex]
So the final ratio is
[tex]2 : 5 : 1[/tex]
The final empirical formula is [tex]C_2 N_5 H[/tex]

Answer:
D. individual electron
Explanation:
Every individual electron will have its own unique set of quantum numbers.
What are quantum numbers?
Quantum numbers are the numbers which describe the values of conserved quantities with respect to the dynamics of a quantum system.They correspond to the Eigen values of operators which commute with the Hamiltonian quantities.
The Hamiltonian quantities can be known with precision simultaneously with the system's energy.Quantum numbers can take values of discrete sets of integers or even half-integers even though they can approach infinity in some cases.
They can specifically describe energy levels of electrons, and can also explain angular momentum,spin,etc.These are used to describe the path of an electron in an atom ,when the quantum numbers of all atoms are combined they must comply with the Schrodinger equation.
