How can you tell S-wave arrival from the end of the P-wave?
Margarita [4]

Answer:

<h2>The P wave will be the first wiggle that is bigger than the rest of the little ones (the microseisms). Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves</h2>

What is the volume (in dm3 of 1 mole of oxygen at 5 MPa and 200 K?
vodka [1.7K]

<u>Answer:</u> The volume of oxygen gas is 0.332dm^3

<u>Explanation:</u>

To calculate the volume of the gas, we use the equation given by ideal gas equation:

PV=nRT

where,

P = pressure of the gas = 5 MPa = 5000 kPa   (Conversion factor: 1 MPa = 1000 kPa)

V = Volume of gas = 3.34 L

n = number of moles of oxygen gas = 1 mole

R = Gas constant = 8.31dm^3\text{ kPa }mol^{-1}K^{-1}

T = Temperature of the gas = 200 K

Putting values in above equation, we get:

5000kPa\times V=1mol\times 8.31dm^3\text{ kPa }mol^{-1}K^{-1}\times 200K\\\\V=0.332dm^3

Hence, the volume of oxygen gas is 0.332dm^3

Nucleotides polymerize via condensation reactions. The reaction forms a new covalent bond—a phosphodiester linkage, or a phospho
Finger [1]

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.
