Answer:

weak acid

Explanation:

pH scale is from 0 to 14

pH =7 is for water which is neutral.  it is neither acidic or basic as the hydrogen ion concentration is equal to hydroxyl ion concentration.

Lesser the pH value than 7 greater the acidic nature. And greater the pH value  than 7 more the basic nature.

Given pH=3-7 So the indicated interval represents weakly acidic.

The "correct" mass of the cylinder had been previously determined to be 27.20 grams. What was the percent error on his first wei
Paraphin [41]

Answer:

Percent error =  - 8.1 %

Explanation:

Given data:

Actual mass = 27.20 g

Theoretical mass = 25.01 g

Percent error = ?

Solution:

Formula:

Percent error = theoretical value- actual value/ actual value × 100

Now we will put the values in formula.

Percent error =   25.01 - 27.2 / 27.2 × 100

Percent error = -2.19 / 27.2 × 100

Percent error = -0.081  × 100

Percent error =  - 8.1 %

What is the acronym for DNA??
victus00 [196]
The acronym 'DNA' stands for deoxyribonucleic acid.   

DNA is used to 'code' the genetic makeup of all living organisms, and is found inside the nucleus of the cell(Eukaryotes) or just floating in the cytoplasm of the cell(Prokaryotes).  DNA is made up of 4 different pairs of base molecules(nucleotides) that are slightly different from another.  The similar molecule structure RNA(ribonucleic acid) differs from DNA in that RNA nucleotides are just slightly different from the nucleotides of DNA.  This difference is that RNA nucleotides have a hydroxide group(OH) where the DNA nucleotides just have a hydrogen atom.  
Because the DNA nucleotide doesn't have the hydroxide group it has one less oxygen than RNA nucleotides do.  This is where DNA derives the prefix "deoxy-," meaning "without oxygen."  
The prefix "ribo-" is given to molecules with a certain configuration of a set of 3 consecutive but not necessarily contiguous CHOH(asymmetric) groups.
The combined form "nucleo-" is used to imply something that has to do with the nucleus, such as the nucleus of a cell where DNA is stored in Eukaryotes.  
And finally, the ending of the acronym: "acid." DNA is an acid because the 4 nucleotides each contain a phosphate group, which are acidic.

And thus, we get our answer: deoxyribonucleic acid, and the meaning:
deoxy-ribo-nucleic acid
(without oxygen) + (has 3 CHOH groups) + (in/of the nucleus) + (acidic)
Thus, DNA is a molecule is basically an acidic molecule residing in the nucleus with 3 CHOH groups and is missing oxygen atoms.

I know this isn't really what you're looking for, but honestly I had a great time doing a little research into the name!

Hope this explains it a little! c;
