2NO(g) plus O2(g) equals 2NO2(g). equilibrium equation:

20.7 g NO2 is produced when 13.5 g NO x 1 mol NO / 30 g x 2 mol NO2 / 2 mol NO x 46 g NO2/mol NO is combined.

The amount of NO2 generated is 5.17 g O2 x 1 mol O2/32 g x 2 mol NO2/1 mol O2 x 46 g NO2/mol.

NO2 formation's maximum mass is 149 g.

Limiting reagent's formula is O2.

The leftover mass of excess reagent (NO) is...

Initial moles: 0.45 moles at 13.5 g NO x 1 mol NO/30 g

The formula is: 5.17 g O2 x 1 mol/32 g x 2 mole NO utilized/mol O2 = 0.323 moles NO used up.

0.45 mol - 0.323 mol = 0.127 mol x 30 g/mol = 3.81 g NO remaining is the mass of NO that is still present.

The correct order of the increasing polarity of the analyte functional group isEthers < Esters.

The given statement is "Polarities of analyte functional group increase in the order of hydrocarbon ethers < esters."  The order of polarities of functional groups is the order of their increasing polarity (i.e., less polar to more polar) based on their electron-donating or withdrawing ability from the rest of the molecule.Polarity of analyte: The analyte's polarity is directly proportional to the dipole moment of the functional group, which is associated with a difference in electronegativity between the atoms that make up the functional group.The electronegativity of an element is its ability to attract electrons towards itself. The greater the difference in electronegativity between two atoms, the more polar their bond, and hence the greater the polarity of the molecule.

To find the correct order of the increasing polarity of the analyte functional group, let's first compare the two groups: hydrocarbon ethers and esters. Here, esters have a carbonyl group while ethers have an oxygen atom with two alkyl or aryl groups. The carbonyl group has more electronegative oxygen, which pulls electrons away from the carbon atom, resulting in a polar molecule. On the other hand, ethers have a less polar oxygen atom with two alkyl or aryl groups, making them less polar than esters. Therefore, the correct order of the increasing polarity of the analyte functional group isEthers < Esters.

This equation demonstrates that charge is conserved throughout the process because the total charge of the reactants equals the total charge of the products.

3Fe³+ + 2Al → 2Fe²+ + 2Al³+

The conservation of charge is the idea that the total electric charge of the reactants and the total electric charge of the products must match a chemical process. This implies that both sides of the equation must have an equal amount of protons and electrons, the positive and negative charges.

Each of the provided chemical equations calls for the exchange of electrons between various atoms. For instance, the aluminum atoms lose three electrons each to form Al3+ ions in the equation 3Fe3+ + 2Al  2Fe2+ + 2Al3+ while the iron atoms gain one electron each to create Fe2+ ions.

0.0731 g/L is the density of  hydrogen gas at a pressure of 0.845 atm and a temperature of 59 °C.

Given data :

Let's start from the ideal gas law:

PV = nRT

Density = mass / volume. While the ideal gas equation includes volume (V), how can we get the mass of the gas? Well, we know that the mass of a sample is related to the number of moles (n) present. By using the molar mass of the gas, we can convert moles to mass. Since our gas is hydrogen, the molar mass of the gas is 2.016 g/mol (don't forget that hydrogen gas is diatomic!)

n = m/M ; n = moles, m = mass (g), M = molar mass (g/mol)

If we substitute "m/M" in for "n" into our ideal gas equation, we get:

PV = (m/M) RT

We can now use algebra to rearrange this equation to solve for m/V (density).

m/V = PM / RT

m/V = (.965 atm)(2.016 g/mol)/(0.0821 L*atm/mol*K)(324 K)

m/V = 0.0731 g/L

Barrier that must be overcome before products are formed in a spontaneous reaction is Activation energy barrier.

A spontaneous response is a response that favors the formation of products on the conditions underneath which the response is occurring. A roaring bonfire is an instance of a spontaneous response, in view that it is exothermic (there is a decrease inside the power of the system as energy is released to the environment as warmth).

Maximum spontaneous chemical reactions are exothermic - they release warmness and heat up their surroundings: for instance: burning wooden, fireworks, and alkali metals introduced to water. When a radioactive atom splits up, it releases strength: that is a spontaneous, exothermic nuclear reaction.

Raoult's Law is a nonvolatile solute lowers the vapour pressure of the solvent.

It is expressed as:

\(P_{\text{soln}} = x_{\text{solvent}} P_{\text{solvent}}\)

where,

\(P_{\text{sol}\) = vapor pressure of the solution

\(x_{\text{solvent}}\) = mole fraction of the solvent

The molar concentration of the HCl solution is 1.2 M.

The balanced chemical equation for the reaction between HCl and NaOH is:

HCl (aq) + NaOH (aq) → NaCl (aq) + H₂O (l)

From the equation, we can see that one mole of HCl reacts with one mole of NaOH.

Given that 15.0 mL of 0.40 M NaOH is required to neutralize 5.0 mL of HCl, we can use the following equation to calculate the concentration of HCl:

moles of NaOH = concentration of NaOH x volume of NaOH (in liters)

moles of HCl = moles of NaOH (since they react in a 1:1 ratio)

concentration of HCl = moles of HCl / volume of HCl (in liters)

Converting the volumes to liters:

Volume of NaOH = 15.0 mL = 0.015 L

Volume of HCl = 5.0 mL = 0.005 L

Substituting the values:

moles of NaOH = 0.40 M x 0.015 L = 0.006 moles

moles of HCl = 0.006 moles (since they react in a 1:1 ratio)

concentration of HCl = 0.006 moles / 0.005 L = 1.2 M

As a result, the HCl solution has a molar concentration of 1.2 M.

Answer: 30.7 moles

Explanation:

The final gas volume, O, could be either larger or smaller than 2.96 L, depending on the final pressure and temperature. While heating the gas to a higher temperature, O could be larger than 2.96 L, but it could also be smaller.

The final gas volume, O, could be either larger or smaller than 2.96 L, depending on the final pressure and temperature. To understand why, we can look at the ideal gas law equation, PV = nRT. In this equation, P represents pressure, V represents volume, n represents the number of moles of gas, R is the gas constant, and T represents temperature.

Let's analyze the situation given in the question. We have a sample of xenon gas at a temperature of 306 K and a pressure of 0.847 atm, occupying a volume of 2.96 L. Now, if the pressure of the gas is decreased, while at the same time it is heated to a higher temperature, the final gas volume, O, could be either larger or smaller than 2.96 L.

If we decrease the pressure while keeping the temperature constant, according to Boyle's law, the volume of the gas will increase. So, in this case, O would be larger than 2.96 L. However, if we simultaneously increase the temperature while decreasing the pressure, the situation becomes more complex. The combined effect of the pressure decrease and temperature increase could lead to different outcomes for the final volume.

For example, if the pressure decrease is significant and the temperature increase is relatively small, the volume may still increase, resulting in O being larger than 2.96 L. On the other hand, if the pressure decrease is small and the temperature increase is significant, the volume may actually decrease, resulting in O being smaller than 2.96 L.
