The volume of N₂ at STP=56 L

Given

2.5 moles of N₂

Required

The volume of the gas

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, the volume per mole of gas or the molar volume-Vm is 22.4 liters/mol.

So for 2.5 moles gas :

\(\tt 2.5\times 22.4=56~L\)

Answer:

C. change in internal energy is zero

Explanation:

Let's say we have a scenario of an ideal gas which is in a system that is isolated, and which is filled inside a flask that is connected to another flask and separated by a valve. If this valve gets to be opened, the gas is going to spontaneously fill the other flask through expansion.

Then we would have

work done , W = -P∆V = 0.

With vacuum, P equal 0.

Since there is a complete isolation of this system, we would have bit that no heat exchange is happening.

Q = 0

Using the first law of thermodynamics,

∆U= Q + W = 0

Therefore we conclude that the change in internal energy is zero

we would need 2625.13 grams (or 2.62513 kilograms) of NaCl.

To calculate the mass of NaCl required to produce a 26.4 mol/L solution with a 1.7 L volume, we need to use the formula that relates the mass of solute, moles of solute, and molarity:Molarity (M) = moles of solute / liters of solution Rearranging this formula, we get:moles of solute = Molarity (M) x liters of solutionWe can use this formula to find the moles of NaCl needed:moles of NaCl = 26.4 mol/L x 1.7 L = 44.88 molNow, we can use the molar mass of NaCl to convert from moles to grams. The molar mass of NaCl is 58.44 g/mol:mass of NaCl = moles of NaCl x molar mass of NaClmass of NaCl = 44.88 mol x 58.44 g/mol = 2625.13 gTo produce a 26.4 mol/L solution with a 1.7 L volume.

The mass of 4.35 × 10^-2 mol of NaOH is 1.74 grams.

Given

Number of moles = 4.35 x 10^-2

First, we calculate the molar mass of NaOH,

Molar mass of NaOH = (1 × atomic mass of Na) + (1 × atomic mass of O) + (1 × atomic mass of H)

= (1 × 22.99 g/mol) + (1 × 16.00 g/mol) + (1 × 1.01 g/mol) = 40.00 g/mol

Molar mass of NaOH = 40.00 g/mol

Mass of NaOH = Number of moles × Molar mass

                          = 4.35 × 10^-2 mol × 40.00 g/mol  

Mass of NaOH  = 1.74 g

The option that describes a situation in which reduction occurs is Cl₂ becoming Cl⁻

In chemistry, reduction means a class of chemical reactions in which the number of electrons associated with an atom or group is increased.

A compound that accepts electrons is said to be reduced.

Situations in which reduction occurs include:

Cl₂ ⇒Cl⁻

When reduction occurs, the oxidation number (superindex) appears to decrease that number. In this case 2+ becomes 1-.

Note:

As with other problems, a decreasing oxidation number means that the compound or element is being reduced (gaining electrons), while an increasing oxidation number means it is being oxidized (losing electrons). increase.

The polar molecule different from a non-polar molecule is  option A) Polar molecules have charges separated like poles of a magnet.

Polar molecules and non-polar molecules differ in terms of their distribution of electrical charge.  This results in an uneven distribution of charge, with one side of the molecule having a slightly positive charge (δ+) and the other side having a slightly negative charge (δ-).

This charge separation occurs when there is an uneven distribution of electrons within the molecule, resulting in a molecular dipole. The positive and negative charges are like the poles of a magnet, with one end being slightly positive (δ+) and the other end slightly negative (δ-).

In contrast, a non-polar molecule has an even distribution of electrons and does not have a significant separation of charges. The electrons are shared equally among the atoms in the molecule, resulting in a neutral overall charge and no distinct positive or negative ends.The correct answer is option A.

Evaporation causes the dew to vanish when the temperature of the atmosphere rises with the rising of the sun.

A kind of vaporization called evaporation takes place on the surface of a liquid as it transitions into the gas phase. When humidity impacts the rate of evaporation of water, for example, a high concentration of the evaporating material in the surrounding gas considerably slows down evaporation.

Similar to how perspiration evaporates from your body on a hot day to cool you down, dew evaporates as it cools the plant. This lessens heat exhaustion in extremely hot settings. Some species, particularly desert plants, are capable of directly absorbing water via their leaves.

Thus, Evaporation causes the dew to vanish when the temperature of the atmosphere rises with the rising of the sun.

Answer:

Br-CH2-CH(CH3)2-C(Cl)H-CH(CH3)2-CHO

Explanation:

The molecule has a total of 14 carbon atoms, 13 hydrogen atoms, and 1 bromine atom. The carbon atoms are arranged in a chain with a methyl group attached to the second carbon atom, a chlorine atom attached to the third carbon atom, and two methyl groups attached to the fourth carbon atom. The fifth carbon atom has a carbonyl group attached to it.

The molecule is an aldehyde, which means that it has a carbonyl group (C=O) at the end of the chain. The carbonyl group is polar, and the oxygen atom has a partial negative charge. The hydrogen atom has a partial positive charge. This polarity makes the aldehyde group susceptible to nucleophilic attack.

The bromine and chlorine atoms are both electrophilic, which means that they have a partial positive charge. This makes them susceptible to nucleophilic attack.

The methyl groups are non-polar and do not have any significant reactivity.

The molecule is a chiral molecule, which means that it has a mirror image that is not superimposable on itself. This is because the carbon atom with the carbonyl group is attached to four different groups.

The molecule is a liquid at room temperature and has a strong odor. It is used in a variety of products, including perfumes, flavorings, and plastics.

Ammonia can be prepared using Haber process based on the following equation:

3H2 + N2 <.........> 2NH3Explanation:

The reaction above talks about the production of ammonia NH₃

To solve this question, we'll begin by writing the balanced equation for the reaction between H₂ and N₂. This is illustrated below:

3H₂ + N₂ —> 2NH₃

From the balanced equation above,

3 moles of H₂ reacted to produce 2 moles of NH₃.

Therefore, 26 moles of H₂ will react to produce = (26 × 2)/3 = 17.3 moles of NH₃.

Thus, 17.3 moles of NH₃ were obtained from the reaction.

The following two structures are identical.

Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers. Therefore, the compounds that exhibit isomerism are known as isomers.

The word “isomer” is derived from the Greek words “isos” and “meros”, which mean “equal parts”. This term was coined by the Swedish chemist Jacob Berzelius in the year 1830.

Structural isomerism is commonly referred to as constitutional isomerism. The functional groups and the atoms in the molecules of these isomers are linked in different ways. Different structural isomers are assigned different IUPAC names since they may or may not contain the same functional group. In the picture, we can see that IUPAC nomenclature also of the two structures are same hence they are identical.
