The transfer of electrons from one reactant to another occurs during an oxidation-reduction (redox) reaction.

Numerous processes that you have already examined, such as single replacement, combustion, and combination, are redox processes. The loss of electrons is called oxidation. Gaining electrons is what reduction is. In the process, electrons are lost and gained simultaneously. For instance, when oxygen and elemental calcium react, calcium oxide is the result.

what volume in gas would be produced by the complete reaction of solid at stp according to the following reaction?remember mol of an ideal gas has a volume of lat stp.

Answers

3.648 liters of volume in gas would be produced by the complete reaction of solid at STP according to the reaction as 1 mole of an ideal gas has a volume of 22.4 L at STP.

How is the volume in gas calculated?

The given reaction is

[tex]2 Al(s) + 6 HCl (aq)[/tex] = [tex]2AlCl[/tex]₃([tex]aq[/tex])[tex]+H[/tex]₂([tex]g[/tex])

1mole of ideal gas is 22.4L

Here we have to convert the mass of Al to moles.

We know, Number of moles = Mass/Molar mass

Mass of Al = 2.93 g

Molar mass of Al = 26.98 g

Therefore, No. of moles = 2.93 g/26.98 g = 0.108 moles

The molar ratio of Al to H₂ is 2:3

As, 2 moles of Al can produce 3 moles of H₂

Then, 0.108 moles of Al can produce

(0.108 × 3)/ 2  

= 0.163 moles of H₂

Now by applying the Ideal Gases Law to calculate the volume that is been produced throughout the reaction at STP ,

The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atmosphere.

1 atm × V = 0.163 mol × 0.082L.atm(mol.K)⁻¹ × 273K

Hence,

V = (0.163 mol × 0.082 L.atm(mol.K)⁻¹ × 273K) / 1atm

V = 0.013366 × 273

Therefore, the Volume is 3.648 L

What is STP?

In chemistry, STP stands for Standard Temperature and Pressure. STP is most commonly used when doing gas calculations. B. Gas Density. The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atmosphere. This is the freezing point of pure water at atmospheric pressure at sea level.

what is the volume inside a 0.250 l can of deodorant that starts at 25 c and 1.2 atm if the temperature is raised to 100 oc?

Answers

The volume inside a deodorant can is 0.199 L.

Charles’s law applies when a fixed amount of gas is in a container and the pressure is constant if the temperature increases the volume of gas also increases. The formula

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

V1 = volume of gasses before the temperature risesT1 = temperature of gasses before the temperature rises (K)V2 = volume of gasses after the temperature risesT2 = temperature of gasses after the temperature rises (K)

The temperature units have to be in Kelvin. Volume units can be anything as long as both volume has the same units.

When a container is heated, the gas in it will experience a temperature increase and the volume of the gas will expand. But the expansion will not exceed the contents of the container.

V2 = 0.250 LT1 = 25 °C + 273 = 298 Kp = 1.2 atm T2 =100 °C + 273 = 373 K

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

[tex]\frac{V_1}{298} = \frac{0.25}{373}[/tex]

V1 x 373 = 298 x 0.25

dw = p (v - u)

When the work is done by the system against external pressure then dw = pdv

Explain the relationship of oxidation numbers to electron confguration for Groups IA through VITA. How can an atom's electron configuration be predicted on the basis of its location in the periodic table?

Answers

The oxidation numbers of the elements show us the number of electrons lost or gained which is traceable from the electron configuration which in turn depends on the group that the atom belongs to.

What is the oxidation number?

The oxidation number is the number of charges that an atom appears to have. We know that the elements that we find in the groups  IA through VIA only have a narrow range of oxidation numbers. This is because the oxidation numbers does depend on the number of electrons that the atom can be able to loose or gain at a time.

We know that each of the groups are known by the maximum number of electrons that can be found on the outermost shell of the atom. This is part of the electron configuration of the atom. Thus, if we know the group that an atom belongs to, we can at least tell the outer electron configuration of the atom because we know that all the atoms in that group have the same outer electron configuration.

What is combustion ?

Combustion, a chemical reaction between substances, usually containing oxygen, that involves the production of heat and light, usually in the form of a flame. The speed or rate at which reactants combine is partly due to the nature of the chemical reaction itself, and partly due to the more energy produced than can escape to the surrounding medium, the temperature of the reactants is used to rise. further accelerate the reaction.
