Approximately 0.323 half-lives have occurred over the period of 1.00 hour.

To determine the concentration of N₂O₅ after 1.00 hour and the number of half-lives that occurred, we can use the first-order rate equation and the concept of half-life.

The first-order rate equation is given by:

ln([A]t/[A]₀) = -kt

Where [A]t is the concentration at time t, [A]₀ is the initial concentration, k is the rate constant, and t is the time.

Given that k = 6.22 x 10^(-5) s^(-1), [A]₀ = 0.500 M, and t = 1.00 hour = 3600 seconds, we can substitute these values into the equation.

ln([A]t/0.500) = -(6.22 x 10^(-5))(3600)

ln([A]t/0.500) = -0.22392

[A]t/0.500 = e^(-0.22392)

[A]t = 0.500 * e^(-0.22392)

[A]t ≈ 0.500 * 0.7997

[A]t ≈ 0.3999 M

Therefore, the concentration of N₂O₅ after 1.00 hour is approximately 0.3999 M.

To calculate the number of half-lives, we can use the equation:

t₁/2 = ln(2)/k

t₁/2 = ln(2)/(6.22 x 10^(-5))

t₁/2 ≈ 11126.03 seconds

Number of half-lives = t/t₁/2

Number of half-lives = 3600/11126.03

Number of half-lives ≈ 0.323

Therefore, approximately 0.323 half-lives have occurred over the period of 1.00 hour.

Approximately 0.268 grams of sodium azide needs to be loaded into the airbag to fully inflate it at standard temperature and pressure.

To calculate the amount of sodium azide required to inflate an airbag, we first need to understand the chemical reaction that takes place. The sodium azide reacts with the potassium nitrate inside the airbag to produce nitrogen gas, which inflates the bag. The reaction is as follows:

\(2NaN_3 + 2KNO_3 \rightarrow3N_2 + 2Na_2O + K_2O\)

From the balanced chemical equation, we can see that 2 moles of sodium azide (NaN3) react to produce 3 moles of nitrogen gas (N2).

The volume of the airbag is given as 139 liters, which is equivalent to 0.139 cubic meters. At standard temperature and pressure (STP), the volume of one mole of gas is 22.4 liters. Therefore, the number of moles of nitrogen gas required to fill the airbag is:

n = V/STP = 0.139/22.4 = 0.00620 moles

To produce 3 moles of nitrogen gas, we need 2 moles of sodium azide. Therefore, the number of moles of sodium azide required is:

n(NaAzide) = (2/3) x n(N2) = (2/3) x 0.00620 = 0.00413 moles

The molar mass of sodium azide is 65 grams/mole. Therefore, the mass of sodium azide required to inflate the airbag is:

Mass = n(NaAzide) x Molar mass = 0.00413 x 65 = 0.268 grams

To fully inflate an airbag, about 50 grams of sodium azide is required. This chemical is stored in the airbag and when the sensor detects a crash, it is ignited, producing nitrogen gas which inflates the bag.

Sodium azide is a highly toxic and explosive substance, and must be handled with great care during the manufacturing and installation of airbags. Once the airbag is deployed, the nitrogen gas produced by the reaction of sodium azide with a metal oxide is harmless and rapidly dissipates into the atmosphere.It is important to note that tampering with an airbag or attempting to remove sodium azide from an airbag is extremely dangerous and should never be attempted. Only trained professionals should handle airbag installation and removal.

Explanation:

apply Charles formula

i.e; V1/T1= V2/T2

here V1= 8.5L

T1= 31°C

T2= -15°C

V2= ?

substitute the values in the above equation;

V2= 8.5/31x(-15)

V2= 0.2741x(-15)

V2= -4.11

The concentration of HNO3 (nitric acid) is 0.06 M.

To find the concentration of HNO3 (nitric acid), we can use the equation:

M1V1 = M2V2

where:

M1 = initial concentration of HNO3

V1 = initial volume of HNO3

M2 = final concentration of HNO3 (which is what we're trying to find)

V2 = final volume of HNO3

Given:

V1 (initial volume of HNO3) = 0.40 L

M2 (final concentration of HNO3) = ?

V2 (final volume of HNO3) = 0.12 L

MNaOH (concentration of NaOH) = 0.2 M

First, let's calculate the number of moles of NaOH used:

moles of NaOH = MNaOH * VNaOH = 0.2 M * 0.12 L = 0.024 mol

Since the balanced chemical equation between NaOH and HNO3 is 1:1, we know that the number of moles of HNO3 is also 0.024 mol.

Now, we can rearrange the equation M1V1 = M2V2 to solve for M1:

M1 = (M2V2) / V1

M1 = (0.024 mol) / 0.40 L

M1 = 0.06 M

Therefore, the concentration of HNO3 (nitric acid) is 0.06 M.

Explanation:

Electron is a subatomic particle with a negative charge of -1e unlike the proton which has a positive charge of +1e

In an atom, an electron has a net negative charge revolving in orbits around the nucleus.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:

\( T_{1}= 94.75 K\)

Explanation:

Given the following data;

Final pressure, P2 = 760 Torr

Initial pressure, P1 = 320 Torr

Final temperature, T2 = 225K

To find the initial temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

\( PT = K\)

\( \frac{P1}{T1} = \frac{P_{2}}{T_{2}}\)

Making T1 as the subject formula, we have;

\( T_{1}= \frac{P_{1}}{P_{2}} * T_{2}\)

Substituting into the equation, we have;

\( T_{1}= \frac{320}{760} * 225 \)

\( T_{1}= 0.4211 * 225 \)

\( T_{1}= 94.75 K\)

Therefore, the initial temperature of the gas is 94.75 Kelvin.

The mass of the water vapor is 13.73 g.

The law of conservation of mass is a fundamental principle in physics and chemistry that states that the total mass of a closed system remains constant during a chemical reaction or physical change. This means that the mass of the reactants in a chemical reaction must equal the mass of the products that are formed.

In other words, the mass of the products that are formed in a chemical reaction cannot be created or destroyed, but only converted from one form to another.

Knowing that;

Total mass of the reactants = Total mass of the products

5 + 10 = 1.27 + x

x is the amount of the water vapor

Enantiomers will rotate plane polarized light in equal amounts but in opposite directions.

Enantiomers are a pair of molecules that are mirror images of each other but cannot be superimposed onto each other. Due to their different three-dimensional structures, they have the ability to rotate the plane of polarized light. When a sample of enantiomers is exposed to plane polarized light, each enantiomer will rotate the light in an equal amount but in opposite directions. This phenomenon is known as optical rotation.

Therefore, it can be concluded that enantiomers will rotate plane polarized light in equal amounts but in opposite directions, which is a characteristic feature of these mirror-image molecules.


Enantiomers are pairs of molecules that are mirror images of each other but cannot be superimposed. They have the same chemical properties but can exhibit different optical properties. When plane-polarized light passes through a solution containing one enantiomer, it will rotate the light in a specific direction, either clockwise (+) or counterclockwise (-). When the same light passes through a solution containing the other enantiomer, it will rotate the light in the opposite direction, with the same magnitude.

enantiomers have the unique property of rotating plane-polarized light by equal amounts but in opposite directions, making them optically active compounds.

It's difficult to treat high radiation exposure.

Explanation:

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.

Radiation is both harmful and beneficial, but when we analyse it is found that harms overweight benefits. Radiation can be used as a form of energy (in nuclear plants), but an accident or malfunction in it can lead to death and injury of humans. Also, it is really difficult to dispose the used devices.

Aluminum ion has a charge of 3+, Al³⁺, and sulfate is SO₄²⁻, so the compound aluminum sulfate has to have a number of aluminum and sulfate such that the final charge is zero, so the proportion on aluminum sulfate is:

That way we have 6+ and 6-, so neutral compound.

This means that for 1 mol of aluminum sulfate, we have 2 moles of aluminum ion. The molar concentration is the number of moles of solute divided by the volume of solution, so it is directly proportional to the number of moles.

So, we can use a rule of three as follows:

aluminum ion --- aluminum sulfate

2 --- 1

x --- 0.646 M

So:

So, the concentration of aluminum ion in this solution is 1.292 M.
