3. Why is it necessary to use structural formulas to represent many organic compounds

Chemistry

Structural formulas are helpful because they explain the properties and structure of the compound which empirical and molecular formulas cannot always represent.

Answer:

See below.

Explanation:

Because there maybe isomers which have the same molecular formula but different structures.

For example some mono-saccharides   have a molecular formula C6H12O6, of  which glucose is one,  have 8 different structures (isomers).

If you fill your car tire to a pressure of 32 psi (pounds per square inch) on a hot summer day when the temperature is 35°C (95°
Murrr4er [49]
By Gay Lussacs law you can find the pressure. First both temperatures of Celsius must change to Kelvin by adding 273. Temperature one will be 308K and temperature 2 will be 258K
With this info, you can now find the pressure with Lussacs law

P1 = P2
— —
T1 T2

Pressure 1 is given which is 32 psi so just plug it all in and find P2

32 = x
—— ——
308 258

308x = 8256 (Cross multiply)

X = 26.8 (divide both sides by 308)

Answer is 26.8 PSI

This makes sense because as temperature increases pressure increases, as well as when temperature decreases, pressure decreases. Since it’s a colder day the pressure will be lower.

Explanation :

  • Mercury has a large core of liquid metal.
  • The metal core is of iron metal.
  • The core is surrounded by a mantle which is made up of silica and a solid outer crust.
  • In the case of Mercury, the total core percentage is 42% of the planet while the Earth's core is only 17% of the planet.
  • Mercury has lost part of its mantle and crust that left the mercury with a large metal core.

The drugs Prilosec and Nexium both contain the same active ingredient. Nexium contains a single enantiomer, but Prilosec is a ra
Softa [21]

Answer:

both drugs will be equally effective

Explanation:

A racemic mixture is a substance that contains a 50/50 mixture of the (+) and (-) enantiomers of an optically active compound.

It is important to note that even if a drug occurs as a racemic mixture, only the biologically active enantiomer will interact with the substrate on which the drug acts. The other enantiomer present is just irrelevant. Similarly, its presence does not affect the biological activity of the active enantiomer.

Hence, both Prilosec and Nexium are both equally effective.
