The gas temperature must be 19.46^{0} C.

Given,

n=25 moles, V=20L, P=30 atm.

We know, PV=nRT,

So, T=PV/nR=\frac{30*20}{25*0.08206}=292.4689 K=(292.4689 -273)=19.46^{0} C

<h3>Temperature </h3>

A measure of the average translational kinetic energy per atom or molecule in the system, temperature expresses how hot matter is physically. It is the observable fraction of matter's molar thermal energy; heat transfer happens when two objects with different temperatures exchange energy.

Using a thermometer, one can gauge temperature. It is calibrated using different temperature scales, each of which historically defined itself using a different set of reference points and thermometric materials. The Celsius scale (formerly known as "centigrade," with the unit °C), the Fahrenheit scale (with the unit °F), and the Kelvin scale are the three most used scales (with the unit K).

Which of the statements about peptide bonds are true? The formation of a peptide bond involves a dehydration reaction. A tripept
Mashcka [7]

Answer:

Peptide bonds form from nucleophilic attack by an α‑carboxyl carbon atom on an electron pair of an α‑amino nitrogen atom of another amino acid.

Explanation:

Peptide bond is a form of covalent bond and it is Amide type that is formed between two molecules when carboxyl group react with one molecule of amino group to release molecule of water.The peptide bond are in form pseudo-double bond characteristic; rigid, planar, and stronger than a typical Carboxyl nitrogen single bond.

Peptide bonds form from nucleophilic attack by an α‑carboxyl carbon atom on an electron pair of an α‑amino nitrogen atom of another amino acid.

The solubility of sodium hydrogen carbonate in water 20 degrees is 9.6 g/100 g h2o.
d1i1m1o1n [39]

We can see from the details below that, the value of the solution's molality is 1.14 mol/Kg.

<h3>What is solubility?</h3>

The term solubility has to do with the quantity of solute that is able to dissolve in a given quantity of solvent. We have the solubility of the sodium hydrogen carbonate in water at 20 degrees as 9.6 g/100 g h2o.

Number of moles of sodium hydrogen carbonate = 9.6 g/84 g/mol = 0.114 moles

Number of moles water = 100 g /18 g/mol = 5.55 moles

Mole fraction of sodium hydrogen carbonate is obtainable by the use of the relation;

0.114 moles/0.114 moles + 5.55 moles

= 0.02

Molality of the solution = 0.114 moles/0.1 Kg = 1.14 mol/Kg
