Answer:
4.9cm or 4.90cm
Explanation:
Use column method and align the numbers. Make sure you add the decimal point before you write the answer, otherwise the value would be wrong.
Hey there!:
Given % of Mn=59.1% means 59.1 g of Mn present in 100 g of manganese fluoride.
Molar mass of Mn= 54.938 g/mol
Moles of Mn = mass / molar mass
59.1 /54.938 => 1.07 ≈ 1 mol.
and % of F=40.9% means 40.9 g of of F present in 100 g of manganese fluoride.
Molar mass of F=18.998 g/mol
Moles of F :
40.9 / 18.999 => 2.15 mol ≈ 2 mol.
The mole ratio between Mn:F= 1 : 2
Therefore the empirical formula of manganese fluoride:
=> MnF2=Mn1F2
Hope that helps!
Answer:
The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide
Explanation:
The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.
The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.
The phosphodiester bond binds a C3` with a C5` in both DNA and RNA
(base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2
------>
------> (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2
During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.
Answer:
just tell that someone you like them
OR
you can just make them feel it, I'm sure that someone will get it and if that someone don't then just tell the someone you like them.
and say why them can't it be just her or him ?
I mean that someone is juat one right
