Synthetic reactions in Citric Acid Cycle
★ « Synthetic reactions in Citric Acid Cycle » ★
The overall reaction for the citric acid cycle is as follows: acetyl-CoA + 3 NAD+ + FAD + GDP + P + 2H2O = CoA-SH + 3NADH + FADH2 + 3H+ + GTP + 2CO2. Many molecules in the citric acid cycle serve as key precursors for other molecules needed by cells.hope it is
In the preparation of a certain alkyl halide, 10 g of sodium bromide (NaBr), 10 mL distilled water (H20), and 9 mL 3-methyl-1-butanol (C5H120) were mixed in the round-bottomed flask and allowed to cool for 2 -3 minutes. Then while swirling the flask, 10 mL sulfuric acid (H2SO4) was slowly added to the flask and the mixture was refluxed and later distilled. The mass of the pure product obtained was 6.48 g. Sodium hydrogen carbonate (NaHCO3) was used to remove impurities. (Density of 3-methyl-1-butanol is 0.810 g/mL). The percentage yield will be?
Percentage yield shows the amount of reactants converted into products. The percentage yield of the reaction is 51.7%.
The equation of the reaction is sown in the image attached. The reaction is 1:1 as we can see.
Number of moles of NaBr = 10 g/103 g/mol = 0.097 moles
We can obtain the mass of 3-methyl-1-butanol from its density.
Mass = density × volume
Density of 3-methyl-1-butanol = 0.810 g/mL
Volume of 3-methyl-1-butanol = 9 mL
Mass of 3-methyl-1-butanol = 0.810 g/mL × 9 mL
Mass of 3-methyl-1-butanol = 7.29 g
Number of moles of 3-methyl-1-butanol = mass/molar mass = 7.29 g/88 g/mol = 0.083 moles
Since the reaction is 1:1 then the limiting reagent is 3-methyl-1-butanol
Mass of product 1-bromo-3-methylbutane = number of moles × molar mass
Molar mass of 1-bromo-3-methylbutane = 151 g/mol
Mass of product 1-bromo-3-methylbutane = 0.083 moles × 151 g/mol
= 12.53 g
Recall that % yield = actual yield/theoretical yield × 100
Actual yield of product = 6.48 g
Theoretical yield = 12.53 g
% yield = 6.48 g/12.53 g × 100
% yield = 51.7%

Answer: 3750s Happy To Help
Explanation:
The green light emitted by a stoplight has a wavelength of 505 nm. What is the frequency of this photon? (c = 3.00 × 10⁸ m/s).
Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
The frequency of the photon will be "[tex]5.9405\times 10^{14} \ Hz[/tex]".
According to the question,
Wavelength,
[tex]\lambda = 505 \ nm[/tex]or,
[tex]= 5.05\times 10^{-7} \ m[/tex]
As we know the equation,
→ [tex]c = v\times \lambda[/tex]
or,
→ [tex]v = \frac{c}{\lambda}[/tex]
By putting the values, we get
[tex]= \frac{3.00\times 10^8}{5.05\times 10^{-7}}[/tex]
[tex]= 5.9405\times 10^{14} \ Hz[/tex]
Thus the above answer is right.

Explain the process of ionization in at least 1 paragraph.
Brainliest goes to best explanation!
Explanation:
Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

Biểu thức định luật Raoul là?
Answer: Định luật Raoult là một định luật hóa học vật lý, với ý nghĩa trong nhiệt động lực học. Được thành lập bởi nhà hóa học người Pháp François-Marie Raoult vào năm 1887, nó nói rằng áp suất một phần của mỗi thành phần của một hỗn hợp chất lỏng lý tưởng bằng với áp suất hơi của thành phần tinh khiết nhân với phần nốt ruồi của nó trong hỗn hợp. Kết quả là, việc giảm áp suất hơi tương đối của dung dịch pha loãng của chất tan không lây bằng với phần nốt ruồi của chất tan trong dung dịch.

On vacation, Aria went scuba diving in the Pacific Ocean for the very first time. She rose toward the surface of the water at a steady speed for 4 minutes. She rose 36 meters in that time. What was her speed? HELP ME ASAP!!!!!!!!!!!!!
Aria speed during scuba diving was 0.15 m/s.
Speed is the ratio of the distance travelled to the time taken. Speed is given by:
Speed = distance / time
Given that the distance travelled was 36 meters and the time was 4 minutes, hence:
Time = 4 minutes × 60 seconds per minute = 240 seconds
Speed = 36 m / 240 s
Speed = 0.15 m/s
Therefore Aria speed during scuba diving was 0.15 m/s.

BY The Editors of Encyclopaedia Britannica | View Edit History
ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

The electron configuration of tin is [Kr] 5s²4d¹⁰5p². The electronic structure of an atom shows the arrangement of electrons in the atom of an element. The electrons are arranged in sub-shells.
Tin is not a transition metal because it has a completely filled d sub-shell and its outermost shell consists of ns, np orbitals.
Tin looses its electrons in pairs. Remember that the outermost orbitals are 5s² 5p². This means that tin can have two stable oxidation states, +2 and +4.
