question 2 options:



inert




greenhouse




poisonous




blue

Answer:

Explanation:

The question requires us to calculate the volume (in L) of a gas under the conditions given.

The following information was provided by the question:

Initial volume of gas = V1 = 2.00 L

Initial temperature of gas = T1 = 25.0 °C

Initial pressure of gas = P1 = 1.08 atm

Final temperature of gas = T2 = 100 °C

Final pressure of gas = P2 = 1.50 atm

To solve this problem, we'll need to apply the equation of ideal gases (shown below) twice: first, to determine the number of moles of gas, and again to calculate the volume of gas under the final conditions. Note that we'll determine the number of moles of gas under the initial conditions because this amount won't change (as we're talking about the same sample of gas).

Propene on reaction with N-bromosuccinimide in CCl4 produces 3-bromopropene.

In this reaction, allylic H atom is replaced with Br atom.

An allylic radical is the kind of reactive intermediate that is created when propene reacts with n-bromosuccinimide (nbs) to produce 3-bromo-1-propene. With NBS as one of the reactants, it is likely that a free radical bromination will take place.

The methyl group in propene would be attacked because the free radical that is forming can only be stabilized via resonance. A radical is said to be allylic if its resonance forms, which individually include unpaired electrons, are all located on an allylic carbon. Depending on where the allylic carbon is located, it can be categorized as a primary, secondary, or tertiary allylic radical.

Explanation:

Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.

Taking into account the reaction stoichiometry and the definition of limiting reactant, HBr is the limiting reagent.

In first place, the balanced reaction is:

2 Al + 6 HBr → 2 AlBr₃ + 3 H₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 54 grams of Al reacts with 485.4 grams of HBr, 73.22 grams of Al reacts with how much mass of HBr?

mass of HBr= (73.22 grams of Al×485.4 grams of HBr)÷54 grams of Al

mass of HBr= 658.166 grams

But 658.166 grams of HBr are not available, 54.96 grams are available. Since you have less mass than you need to react with 73.22 grams of Al, HBr will be the limiting reagent.

First, remember that:

The vapor pressure of a liquid is directly related to the intermolecular forces present between its molecules. If these forces are stronger, the evaporation rate and the vapor pressure will be lower.

So, we're going to analyze the intermolecular forces of each element:

O2: The molecule of oxygen consist of two oxygen atoms bonded together by a double bond. It consist of just London dispersion forces, so this is a really weak force.

H2O: Water has hydrogen bonds, dipole-induced dipole forces, and London dispersion forces. So it has strong forces.

SO: It consists of London dispersion forces, and there's a difference of electronegativity between S and O, so there's a greater force than the force of O2.

Therefore, O2 could have the highest vapor pressure, as its intermolecular forces are the weakest.

Explanation:

Electronegativity is a measure of an atom's ability to pull bonded electrons to itself.

The correct answer is d.

It is a relative scale that quantifies the attraction an atom has for electrons in a chemical bond. A highly electronegative atom has a stronger pull on the shared electrons, resulting in an uneven distribution of electron density within the bond.

This can lead to the formation of polar covalent bonds, where there is a partial positive charge on one atom and a partial negative charge on the other. Electronegativity is an important concept in understanding chemical bonding, as it helps predict the nature of bonds, such as whether they are nonpolar covalent, polar covalent, or ionic.

The half-life for the transmutation of radon-222 that would remain after 1.9 days is approximately 70.71 g.

To calculate the transmutation of radon-222 that would remain after 1.9 days, we can use the concept of half-life.

Half-life of radon-222 (t½) = 3.8 days

Initial mass of radon-222 = 100.0 g

Time elapsed (t) = 1.9 days

The number of half-lives elapsed can be calculated as:

Number of half-lives (n) = t / t½

Substituting the values:

n = 1.9 days / 3.8 days = 0.5

Now, we can calculate the remaining mass of radon-222 using the formula:

Remaining mass = Initial mass × (0.5)^n

Substituting the values:

Remaining mass = 100.0 g × (0.5)^0.5 ≈ 70.71 g

Therefore, approximately 70.71 g of radon-222 would remain after 1.9 days.

The synthesis of carboxylic acid can be done by hydrolysing the nitrile which is substituted in place of halide by using cyanide ion. The structure that contains a nitrile is OCH2C≡N.

A nitrile is an organic compound that contains a carbon triple bonded to a nitrogen atom.

The general formula for a nitrile is R–C≡N, where R is an alkyl or aryl group. In the structure OCH2C≡N, the OCH2 group is the alkyl group and the C≡N is the nitrile functional group. Therefore, this structure contains a nitrile.

To synthesize a carboxylic acid from an alkyl halide, you can first convert the alkyl halide to a nitrile through a substitution reaction with a cyanide ion. The nitrile can then be hydrolyzed to form a carboxylic acid. The overall reaction is:

R–X + CN– → R–C≡N → R–COOH

Where R is an alkyl or aryl group, X is a halogen, and CN– is a cyanide ion.

In conclusion, the structure that contains a nitrile is OCH2C≡N and it can be used to synthesize a carboxylic acid from an alkyl halide through a substitution reaction followed by hydrolysis.

The heat of solution (qsoln) for the neutralization reaction between nh3 and hcl can be calculated using the heat of neutralization equation: qsoln = -qrxn/moles of solute. The reaction between nh3 and hcl is an exothermic reaction, meaning it releases heat. The balanced chemical equation for the reaction is:

NH3 (aq) + HCl (aq) → NH4Cl (aq)

To calculate qsoln, we need to know the amount of heat released (qrxn) and the number of moles of solute. The heat of neutralization for this reaction is -51.4 kJ/mol. This means that for every mole of NH3 and HCl that react, 51.4 kJ of heat are released. To determine the number of moles of solute, we need to know the amount of NH3 and HCl present in the reaction.

Let's say we have 100 mL of a 0.1 M NH3 solution and we add 50 mL of a 0.1 M HCl solution to it. The total volume of the solution is 150 mL, and the total number of moles of NH3 and HCl is:

moles of NH3 = (0.1 mol/L) x (0.1 L) = 0.01 moles
moles of HCl = (0.1 mol/L) x (0.05 L) = 0.005 moles

The limiting reactant is HCl, so we can use its moles to calculate qsoln:

qsoln = -qrxn/moles of solute
qsoln = -(-51.4 kJ/mol)/(0.005 mol)
qsoln = 10,280 kJ/mol

Therefore, the heat of solution (qsoln) for the neutralization reaction between NH3 and HCl is 10,280 kJ/mol.

Decomposition of hydrogen peroxide has a thermodynamic instability. It decomposes at higher temperatures and concentrations to form water and oxygen. Other compounds, such as transition metals like silver and platinum, can catalyze the decomposition of hydrogen peroxide.

In the absence of a catalyst, the reaction of hydrogen peroxide decomposition is very slow at moderate temperatures. It can be accelerated by raising the temperature, which initiates the thermal decomposition reaction. This reaction can take place in either the liquid or vapour phase.

\(H_{2} O_{2}\) is the chemical formula for hydrogen peroxide. It is a very pale blue liquid that is slightly more viscous than water in its pure form. It is used as an oxidizer, bleaching agent, and antiseptic in water, usually in a dilute solution (3%-6% by weight) for consumer use, and in higher concentrations for industrial use. Concentrated hydrogen peroxide, also known as "high-test peroxide," decomposes explosively when heated and has been used as a rocket propellant.
