Hydrogen bonds

Guanine-cytosine and adenine-thymine <em>hydrogen bonds</em> hold the strands of a DNA helix together.

Answer:

Hydrogen bonds

Explanation:

Hydrogen bonds are the intermolecular forces responsible for base pairing and double helix stability in DNA.

The hydrogen bonds that bind the two strands of DNA are “weak” covalent bonds, meaning they easily denature, which means that they separate and reconnect very easily.

Regarding the nitrogenous bases of DNA, Adenine is paired with Thymine, forming the A-T base pair, and there is double hydrogen bonding between these bases. In the same way that guanine binds to cytosine and forms the base pair G-C by triple hydrogen bonding. And the two chains link through weak hydrogen bridges between the nitrogenous bases of nucleotides, responsible for maintaining the double helix structure of DNA.

OLga [1]
Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.

What type of reaction occurs initially with sodium azide when airbags initially deploy.
Luden [163]

The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.

An lemon in white light appears yellow to the human eye because yellow light is (reflected, absorbed, transmitted) by the lemon'
Arada [10]

We see that colour which is reflected by the surface because the object is made up of that colour.

<h3>What is the colour of lemon in white light?</h3>

A lemon in white light appears yellow to the human eye because yellow light is reflected by the lemon's surface while all other wavelengths of light are absorbed.

If the same lemon is placed into red light. It will appear to look red. This occurs because the red light will be transmitted by the lemon's surface and red light will be reflected to your eye.

So we can conclude that we see that colour which is reflected by the surface because the object is made up of that colour.

The solubility of manganese (ii) hydroxide (mn(oh)2) is 2.2 x 10-5 m. what is the ksp of mn(oh)2?
frosja888 [35]
-When Ksp is the solubility product constant for a solid substance when it

dissolved in an aqueous solution, and measure the level at which a solute

dissolves in the solution.

- and we have the solubility and it is the maximum quantity of solute which can dissolve in a certain solute 

we can assume the solubility = X = 2.2 x 10^-5 M

and when the balanced reaction equation is:

Mn(OH)2(s)  ↔ Mn2+   +  2OH-

∴ the Ksp expression is = [Mn2+] [OH-]^2

when [Mn2+] = X = 2.2 x 10^-5 M

and [OH-] = 2X = 2*(2.2 x 10^-5) = 4.4 x 10^-5 M

by substitution:

∴ Ksp = X * (2X)^2

           = (2.2 x 10^-5)(4.4 x 10^-5)^2

           = 4.3 x 10^-14
