Answer:−27∘C, 19.4 g of molecular oxygen exerts a pressure of 1820 mmHg in a 5.12 L cylinder.

Explanation:The molar mass of O2

is 32.00 g/mol. So, the number of mol (n) of O2 present in 19.4 g of mass is calculated as shown below:

n =19.4g

32.00g/mol

=0.60625mol

The concentration of the iron III bromide solution is 1.13 M.

We know that the concertation is defined as the ratio of the number of moles to the volume of the solution. In this case, the balanced reaction equation that we need to work with have been shown in the image that is attached to the question.

Number of moles of iron (III) oxalate =  2.97 g/376 g/mol = 7.9 * 10^-3 moles

From the reaction equation;

2 moles of the iron III bromide yields 1 mole of the iron (III) oxalate

x moles of the  iron III bromide yields 7.9 * 10^-3 moles of the iron (III) oxalate

x = 2 moles  * 7.9 * 10^-3 moles/ 1 mole

= 0.0158 moles

Given that;

Number of  moles = concentration/ volume

concentration = Number of  moles/ volume

= 0.0158 moles/14 * 10^-3

= 1.13 M

Volume of gas occupy if the temperature of the gas is changed is 529.6 litres

It is given that

Initial volume of gas = V1 = 482 liters

Initial temperature = T1 = 273 K

Final temperature = T2 = 273 + 27 = 300 K

Final volume = V2 = ?

Charles's Law states that the volume of a given mass of gas varies directly with the absolute temperature of the gas when pressure is kept constant. The absolute temperature is temperature measured with the Kelvin scale.

The relationship between volume and temperature is:

V1 / T1 = V2 / T2

where V1 and T1 are the initial volume and absolute temperature and V2 and T2 are the final volume and absolute temperature (the Kelvin temperature, not the Celsius temperature).

V1 / T1 = V2 / T2

482 litres/273 K = V2/300 K

V2 = 529.6 litres

Hence, Volume of gas occupy is 529.6 litres

All amino acids also contain a variable R-group (also known as a "side chain"), and it is this group that distinguishes one amino acid from another.

Explanation:

The side chain of an amino acid differentiates one amino acid from another , good luck..

The variable part of an amino acid, which is the unique chemical structure that distinguishes one amino acid from another, is the side chain.

Organic substances known as amino acids have both amino and carboxylic acid functional groups. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature. In the genetic code, only 22 alpha amino acids are present.

The amino group, carboxyl group, and side-chain or R group are the three components of an amino acid, and they are all joined to the -carbon. One amino acid can be distinguished from another by their R group.

Amino acids, which are tiny chemical compounds with an alpha (central) carbon atom coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component known as a side chain, are the building blocks of proteins.

The required forces are instantaneous and van der wal dispersion respectively

London dispersion forces also referred to as dispersion forces,

London forces, instantaneous dipole-induced dipole forces, fluctuating induced dipole bonds, or loosely as van der Waals forces are a type of force that typically acts between atoms and molecules that are electrically symmetric, meaning that the electrons are distributed symmetrically with respect to the nucleus.

The van der Waals force is a distance-dependent interaction between atoms or molecules that was named after Dutch scientist Johannes Diderik van der Waals. These attractions are not the product of a chemical electronic link, unlike ionic or covalent connections.

They are more prone to disruption since they are relatively weak. Longer distances between interacting molecules result in a rapid disappearance of the van der Waals force.

If the final pressure of water vapor was 0.875 atm and the temperature is 400K, then 6.66 moles of H₂O was produced if we assume that the reaction went to completion in a 250L engine.

It is given to us that the pressure of water vapor is 0.875 atm and the temperature is 400K and the volume of the engine is 250L. Then, the number of moles of water could be found by the following formula,

PV = nRT

Here, R refers to the Universal Gas constant and n refers to the number of moles. Thus, by substituting the values we get the number of moles of H₂O as,

0.875x250 = nx0.0821x400

Boyle's Rule: If the temperature and volume of the ideal gas remain constant in a closed system, the absolute pressure that a given mass of the gas exerts is inversely proportional to the space it takes up.

P1V1 = P2V2

447 × 86.4 = 1240 × V2

V2 = 447 × 86.4 / 1240

V2 = 31.146 mL

At constant temperature (T) and molecular weight (M), volume (V) decreases as pressure (P) increases (n)

PV = nRT

V = nRT/P

V = 4.55 × 0.082 × 285 / 7.32

Where R = ideal gas constant = 0.082 (L) (atm) (mole) -1(K) -1

V is equal to 14.53 L or 14530 cm3.

Charles's Rule: When pressure is held constant, a given mass of gas has a straight relationship between its volume and absolute temperature.

V1T2 = V2T1

1 × 263 = V2 × 310

V2 = 1 × 310 / 263

V2 = 1. 179 L
