write the spontaneous net cell reaction. include physical states. net cell reaction: 2al(s) 2br {2}(l)

ElenaW [278]

The net cell reaction is: 2Al(s) + 2Br2(l) → 4Br(s) + 2Al2O3(s)

What is a net cell reaction?

A net cell reaction is the overall chemical reaction that occurs during a redox reaction in a cell. It is the sum of all of the individual chemical reactions that take place in the cell and is usually written as an equation with the reactants on the left-hand side and the products on the right-hand side.

What is a chemical reaction?

A chemical reaction is a process in which two or more substances interact to form new substances with different chemical properties. Chemical reactions involve the breaking and forming of chemical bonds, releasing or absorbing energy, and can be either exothermic (releasing energy) or endothermic (absorbing energy).

Which atom would tend to gain 1 valence electrons from another atom in order to become stable

Mrrafil [7]

Answer: Option (D) is the correct answer.

Explanation:

Atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.

So, in order to attain stability it tends to gain one electron from a donor atom. Therefore, a chlorine ion is formed as $Cl^{-1}$ .

As it gains only one electron that is why, -1 charge occurs.

Whereas Ar is a noble gas with atomic number 18. As it has completely filled octet so it will be unreactive in nature as it is already stable.

Similarly, He is also a noble gas so it is unreactive in nature.

Atomic number of boron (B) is 5 with electronic distribution 2, 3. So, in order to attain stability it needs to lose 3 electrons.

Thus, we can conclude that Cl is the atom which tends to gain 1 valence electron from another atom in order to become stable.

How do invertebrates affect the oxygen levels of compost and soil?.

Digiron [165]

Invertebrates affect the oxygen levels of compost and soil by reducing it.

<h3>How respiration works?</h3>

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

Every living organism undergoes the process of cellular respiration and make use of oxygen molecules in the process.

This means that invertebrates will make use of the oxygen gas present in compost and the soil for respiration, hereby reducing it.

Describe, in detail, to a freshman undergraduate how to make 1 liter of LB + Kan (100 μg/ml final concentration) + Amp (50 μg /m

mario62 [17]

Answer:

Explanation:

The objective here is to prepare 1 liter of LB + Kan (100 μg/ml final concentration) + Amp (50 μg /ml final concentration) liquid media.

Given that :

the Stock concentration of Amp: 100 mg/ml (since 1 mg/ml = 1000 μg/ml)

it is required that we convert stock concentration in μg/ml since 100 mg/ml = 100000 μg/ml

However, using formula C₁V₁=C₂V₂ (Ampicilin),

where:

C₁ = 100000 μg/ml,

V₁=?,

C₂= 50 μg/ml,

V₂=1000 ml

100000 μg/ml × V₁ = 50 μg/ml × 1000 ml

V₁ = 50 μg/ml × 1000 ml/100000 μg/ml

V₁ = 0.5 ml

Given that:

the Stock concentration of Kan: 25 mg/ml (since 1 mg/ml = 1000 μg/ml)

it is required that we convert stock concentration in μg/ml , 25 mg/ml = 25000 μg/ml

Now by using formula C₁V₁=C₂V₂ (Kanamycin),

C₁ = 25000 μg/ml,

V₁=?,

C₂= 100 μg/ml,

V₂=1000 ml

25000 μg/ml × V₁ = 100 μg/ml × 1000 ml

V₁ = 100 μg/ml × 1000 ml/25000 μg/ml

V₁ = 4 ml

Thus; in 1 lite of Lb+ Kan+Amp preparation;

0.5 ml of Amp & 4 ml of kanamycin is used for their stock preparation.

Finally;

Sterilization step should be carried out in flask (Clean dry glass wares) for media in an autoclave, the container size should be twice the volume of media which is prepared.
