What atom is the site of covalent attachment of amc to the model tetrapeptide used in the studies?.
Answers
The experiment referenced here involves the use of Y32P-ATP. The atom involved in the site of the covalent attachment is the N atom in Aminomethylcyclohexane (AMC).
The explanation in relation to the attachment of AMC to the Moel Tetrapeptide
Given that Aminomethylcyclohexane (AMC) had been linked around the carboxyl side, it, therefore, means that that type of linkage called the Amide-Linkage (That is N-acylation) can be utilized in the covalent bonding of the fluorophore into the peptide

The temperature of CI2 is changed from 836.06K to 625.06K.if it's new volume is 14.509L what was its original volume in liters
Answers
V1= 19.229L
Explanation:
V1/T1 = k
V1/836.06=14.509/625.06
V1/836.06= 0.023
V1 = 19.229L
The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.
What is combined gas law?The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.
It is a mathematical expression that relates Pressure, Volume and Temperature.
(P1 × V1)÷T1 = (P2 × V2)÷T2
We can also use the following relation-
PV = nRT
According to the question, Pressure is constant and we can write the formula as-
V1÷T1 = V2÷T2
T1 = 836.06 K
T2 = 625.06 K
V1 = ?
V2 = 14.509 L
V1 = 19.4 L
Therefore, The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

You are a NASA engineer. You are the chief engineer for the Apollo 13 mission to the moon. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide (NaOH) has been suggested as a means of removing carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. You remember that the astronauts have a 5000. g container of sodium hydroxide on the ship. You also know that sodium hydroxide can be used to remove carbon dioxide.
Use the following reaction: NaOH + CO2 → Na2CO3 + H2O
The astronauts have 2 days left before they land on Earth. You know that there are three astronauts, and each astronaut emits roughly 500. g Of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? SHOW ALL YOUR WORK - DON’T FORGET TO BALANCE THE EQUATION
Guiding Questions: How many grams of CO2 are produced in a day? How many grams of CO2 are produced in both days? How many grams of NaOH do you need to get rid of 3000 g of CO2?
Answers
Answer:
We know that there are three astronauts and each one of them emits 500 grams of carbon dioxide each day, so the total carbon dioxide emitted each day.
Explanation:
From the mole ratio of the reaction, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon
What was of Sodium hydroxide is required?The mass of sodium hydroxide required depends on the mass of CO2 produced by the astronauts.
The mass of CO2 produced by the astronauts is calculated as follows;
Mass of CO2 produced = 3 × 2 × 500 g = 3000 g of CO2
The mass of sodium hydroxide required is calculatedfrom the eqaution of the reaction given below:
[tex]2NaOH + CO_2 → Na_2CO_3 + H_2O \\ [/tex]2 moles of sodium hydroxide reacts with 1 mole of CO2
Molar mass of NaOH = 40 g/mol
Molar mass of CO2 = 44 g/mol
Mass of sodium hydroxide required = 3000 g × 2 × 40/44 = 5454.54 g
Therefore, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon.
