A chemical bond is created by either the transfer or sharing of electrons. Electrons with a missing full outer shell will be the ones participating in the bonding process. Hope this helped :)

Modify isoleucine, below, to show its structure at pH 1 and pH 13.

NeTakaya

I have attached the answer

remember that when the solution is acidic, pH lower than 7. there are extra H+ that the amino acid can take. the basic part of the amino acid takes this extra hydrogen (the nitrogen).

when the pH is higher than 7, basic, there are not much H+ available. the amino acid loses a H+. the acid part of the amino acid loses the H (the carboxylic part).

2.68 x 10^24 atoms of Cu equal how many moles? Help!!!

Scilla [17]

Answer:- $2.68*10^2^4$ atoms of Cu are equals to 4.45 moles.

Solution:- It is a atoms to moles unit conversion for which we divide the given number of atoms by Avogadro number.

$1 mol = 6.02*10^2^3 atoms$

We have been given with $2.68*10^2^4$ atoms and asked to convert them to moles.

The set up for this unit conversion problem would be as:

$2.68*10^2^4 atoms(\frac{1mol}{6.02*10^2^3 atoms})$

= 4.45 moles

So, there would be 4.45 moles of Cu in $2.68*10^2^4$ atoms of Cu.

HURRRRRYYYYYYY!!!!!!!!!!!!!!!!!!!

Vladimir79 [104]

Answer:

Explanation:

What an interesting amusing question.

The formula for KE = 1/2 m v^2.

v implies that there is motion.

The answer you are looking for is the body of water that has 0 for v.

A cloud moves, so it is not the answer.

A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.

Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.

I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
