The first substance is nitric acid, HNO3. Since this substance dissolves to generate an acidic solution, the bond between O and H in the structural formula NO2OH breaks when the substance dissolves, making it an oxyacid. The latter substance, Ni(OH)2, is apparently insoluble in neutral water, but will dissolve if the solution is acidic. This behavior is typical of substances that feature basic anions. The bond between Ni and O is the one that breaks when Ni(OH)2 dissolves. The hydroxide ion that is produced quickly reacts with protons in solution and cannot react again with Ni2 to form a precipitate.

First, we must compute the index of hydrogen deficiency, IHD, using the molecular formula of the compound [tex]C_{10}H_{14}O_{2}[/tex].

What is a spectrum data?

Spectrum data is data collected from spectroscopic experiments, which measure the interaction of matter with electromagnetic radiation. This data can be used to identify the chemical composition of a sample, as different elements and molecules absorb and emit radiation at different wavelengths.

Then, number of C atoms - [tex]\frac{number of atoms}{2} + 1[/tex]

                                          = [tex]10 + \frac{14}{2} + 1[/tex]

                                          = [tex]10 - 7 + 1[/tex]

                                          = [tex]4[/tex]

Based on the molecular structure, this tells us how many multiple bonds and rings the compound has.

This compound contains four unsaturated bonds. We can tell from the spectrum data that it is aromatic (chemical shifts above 6 comes from aromatic protons). Based on this, we can conclude that the structure of this compound contains a benzene ring. Four IHD are found in the benzene ring, one from the ring and three from double bonds.

Following that, IR spectrum data revealed that absorption on [tex]3150-2850 cm^{-1}[/tex] indicated hybridised CH bonds.

The following chemical shifts are observed in the NMR spectrum data:

On 1,4ppm, it becomes a 6H triplet. It has two protons in its neighbourhood because it is a triplet, and it comes from [tex]CH_{3}(1)[/tex]. This group must be linked to the [tex]CH_{2}(2)[/tex].

A quartet on 4,0ppm, belongs to 4H from [tex]CH_{2}(2)[/tex].  It has 3 protons in neighborhood stop it it attached to the [tex]CH_{3}(1)[/tex] and singlet on 6,8ppm comes of aromatic protons, 4H (3).

The flask A, flask B, flask C, all have equal average kinetic energy at 0°C.

The average kinetic energy of the particles in a gas is inversely related to its temperature. These particles must move more quickly as the gas warms because their mass is constant.

KE avg = 3/2RT

As a result, it is possible to state that average kinetic energy depends on temperature. As a result, as the temperature rises, the gas molecules become more energetic and move at a faster rate.

The average kinetic energy also stays the same because, in accordance with the question, the temperature is constant across all flasks.

Answer: -162,120J

Explanation:

Okay, so q stands for work, given by the formula q = -P∆V,

For the first round, we have 2atm (for P) and a volume change of 3.2 (6.4-3.2) for the first experiment.

Find the work: q = -2 • (3.2 - 6.4) = 6.4L/atm

For the second experiment, it is now 2.5atm, with the change in volume going from 3.2 to 2.56.

So, work is q = -2.5(2.5 - 3.20) = 1.6L/atm

Add the total work: 1.6 + 6.4 = 8L/atm

To find the Joules per L/atm, recall that a mol of gas in K is 8.31447J, while the gas constant where a liter of gas per mol in K is 0.08206L/atmK. Divide these two values, which leaves us with 101,325J

So, for the first round, multiply 8 x 101,325, which leaves us with 810,600J.

Second round: The pressure is 2.5atm, with the volume change from 6.40 to 2.56

Solve for work: q = -2.5(2.56-6.4) = 9.6L/atm

Multiply with the Joule unit found earlier: 9.6 x 101,325 = 972,720J.

To find the difference, subtract the value of the single-step process (second round) from the first round (multistep)

810600 - 972720 = -162,120J. Therefore, it takes more heat to do the single step than the multistep process.

Li2O > K2O > Rb2S is the order of given compounds lattice energy in the increasing order

Lattice energy is a measure of the strength of the electrostatic attraction between the positively charged cations and negatively charged anions in an ionic compound. The greater the lattice energy, the stronger the electrostatic attraction and the more stable the compound.The most common method for determining lattice energy is the Born-Haber cycle. This method uses thermochemical data of the individual steps in the formation of an ionic compound to calculate the lattice energy. However, it is often impractical to use this method in a test environment, so a more practical method that is used to compare lattice energies of different compounds is the use of the Coulomb's law which relates the lattice energy to the charge product of the cations and anions and the distance between them.

Explanation:

To determine how many moles of KCI are produced at the same time as 9 moles of O2, you can use the balanced chemical equation for the reaction. The balanced equation for the reaction of potassium chlorate (KCIO3) with oxygen gas (O2) is:

2KCIO3 = 2KCI + 3O2

This equation tells us that for every 2 moles of potassium chlorate that react, 2 moles of potassium chloride (KCI) are produced, along with 3 moles of oxygen gas.

Since we know that 9 moles of O2 are produced, we can use the balanced equation to determine how many moles of KCI are produced as well. Since the ratio of O2 to KCI in the equation is 3:2, we can divide 9 moles of O2 by 3 and multiply the result by 2 to find the number of moles of KCI that are produced:

9 moles O2 / 3 = 3 moles KCI

So, for 9 moles of O2, 6 moles of KCI are produced.

Answer: 6 mol KCI

4 liters of 30% acid must be added to 2 liters of 15% acid to result in a mixture that is 25% acid.

To find the amount of 30% acid that must be added to 2 liters of 15% acid to result in a mixture that is 25% acid, we can use the concept of percentage concentration. The percentage concentration is defined as the ratio of the number of moles of solute (in this case acid) to the total number of moles of the solution.

Let's call x the number of liters of 30% acid to be added. Then the final volume of the solution is (2+x) liters.We know that the final concentration of the solution is 25%, so we can write the following equation:

(moles of acid in 2 liters of 15%) + (moles of acid in x liters of 30%) / (2+x) = 0.25

We can now use the percentage concentration to find the number of moles of acid in each volume of acid:

moles of acid in 2 liters of 15% = (2L * 0.15) = 0.3 moles

moles of acid in x liters of 30% = (xL * 0.30) = 0.30x molesWe can now substitute these values in the equation above:

(0.3) + (0.30x) / (2+x) = 0.25

Solving for x we can find the volume of 30% acid that needs to be added to the 2 liters of 15% acid:

0.3 + 0.30x = 0.25(2+x)

0.3 + 0.30x = 0.5 + 0.25x

0.05x = 0.2

x = 4 L. Therefore, 4 liters of 30% acid must be added to 2 liters of 15% acid to result in a mixture that is 25% acid.
