A gas sample at a certain temperature has an initial volume of 5.345 L. What is the initial temperature of the sample if the volume and the temperature are changed to 4.345 L and 898.0 K, respectively? Assume that the pressure and the amount of the gas remain constant.

Answers

Answer 1

Answer:

1104 K

Explanation:

We can use Charles' Law: [tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Plugging in the numbers gives us the initial temperature to be 1104 K

What is an easy way to define an ion?

An ion is any atom or group of atoms that has one or more electrical charges that are both beneficial and harmful. Ions have either a positive or negative charge, called cations or anions.

Where do ions come from?

Ions are produced when an atom's both electrons and protons are not balanced. As a result, an atom with an either positive or negative voltage that has already accumulated or lost three maybe more elements is referred to as an ion. Ionization is the process of protons moving between molecules and atoms.

The air pressure inside a submarine is 0.62 atm. What would be the height of a column of mercury balanced by this pressure?

Answers

The height of a column of mercury balanced by 0.62 atm pressure is 471.2 mmHg.

What is pressure ?

Pressure is defined as the force applied perpendicular to an object's surface per unit area over which that force is distributed. Gauge pressure is the pressure in relation to the surrounding atmosphere. Pressure is expressed using a variety of units.

The standard air pressure in a mercury-containing vessel keeps the mercury level grown up to 760 mm higher

It is relatively similar to the force from the weight of that column in the vessel.

Given:

0.62 atm air pressure  - inside a submarine,

mercury level at 1 atm = 760 mmHg

The height of the column of mercury balanced by this pressure is as follows:  

= 0.62 × 760 mmHg

= 471.2 mmHg

Thus, the height of a column of mercury balanced by 0.62 atm pressure - 471.2 mmHg

Splicing occurs during transcription. O before capping. before transcription. O after addition of the poly-A tail. O only after transcription is complete.

Answers

Splicing occurs during transcription only after transcription is complete.

In molecular biology, RNA splicing is the process by which a pre-mRNA transcript is converted into a functional mRNA (mRNA). The process is effective because it involves splicing together exons after introns (non-coding sections of RNA) have been removed (coding regions). When a gene is encoded in the nucleus, splicing happens in the nucleus either simultaneously with or shortly after transcription. Splicing is required for the production of an mRNA molecule that can be translated into protein from the introns present in the genes of most eukaryotic organisms.

For many eukaryotic introns, splicing is a multi-step process mediated by the spliceosome, a collection of tiny nuclear ribonucleoproteins (snRNPs). Self-splicing introns, also known as ribozymes, are capable of catalyzing their own excision from the parent RNA molecule. The core postulate of molecular biology is that genes are expressed through the processes of transcription, splicing, and translation.

It took thirty years for anyone to realize that it had the potential to be used as an explosive, primarily because it was too difficult to detonate due to the fact that it was less sensitive than other options.

Carl Haussermann, another German chemist, was the one who made the initial discovery of its explosive capabilities in the year 1891. [7] Because TNT is so insensitive, in 1910 it was exempted from the UK's Explosives Act 1875 and was not regarded as an explosive for the purposes of manufacture and storage. This was because TNT can be safely placed into shell cases when it is in a liquid state.

Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed.  Density of a substances depends on the bond type, temperature and pressure.

Density is an intensive property thus does not change with the change in amount of the substance and remains constant. The units of density are g/ml, g/cm³ etc.

Given the mass of the solvent = 41.3 g

density = 0.7899 g/ml

Water is the most abundant atom is a false statement.

Water molecule is composed of two hydrogen atoms and one oxygen atom. Water is necessary for the survival of living organisms. Water is polar because the oxygen atom in water has a higher electronegativity than the hydrogen atoms, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.

Water stabilizes temperature because it has a high heat capacity, meaning it can absorb or release a large amount of heat without experiencing a significant change in temperature. This allows it to act as a temperature buffer, helping to maintain a relatively stable temperature in living organisms and in the environment.

Why is 9-Fluorenone more polar than fluorene?

The fluorene is first eluted with hexane, which makes it easier to elute 9-fluorone with dichloromethane. 9-fluorenone will be slower because it is attracted to alumina. The stationary phase is non-polar and the mobile phase is polar. Most polar eluted first and least polar eluted second.

Fluorenone is more polar than fluorene because of its C=O. establish closeness. The triple flask should only contain Fluorenone, but it shows contamination of other compounds\
