1 carot = 0.2 grams
1.5 carot = 0.3 grams.

1 mol of Carbon = 12 grams
x mol = 0.3 grams

0.3 * 1 = 12 x
x = 0.3/12
x = 0.025 mol

1 mol of Carbon is 6.02 * 10^23 atoms
0.025 mol of carbon is x

1/0.025 = 6.02*10^23 * /x
x = 0.025 * 6.02 * 10^23
x = 1.5 * 10^22 atoms of carbon.

¿Cuál de los siguientes no es un ejemplo de movimiento de masas?
babunello [35]

Which of the following is not an example of a mass movement?

to. a. Ground slides  b) acid rain  c. mud flow  d. drop

Answer:

b) acid rain

Explanation:

Acid rain is not an example or a type of mass movement.

Mass movement or mass wasting is the movement of rocks, soils and other debris downslope under the influence of gravity.

Water, slope and gravity are triggers of mass movement.

  • Acid rain is a not a form of mass movement
  • It occurs with some certain gases mixes rain water to produce an acidic precipitation.
  • When the water falls to the each surface, it causes problems to the ecosystem and can also corrode building materials.

Hat volume of a 0.540 M NaOH solution contains 12.5 g NaOH
amid [387]

Answer:

At 0.58 L of 0.540 M NaOH solution contain 12.5 g NaOH.

Explanation:

Given data:

At volume = ?

Mass of NaOH = 12.5 g

Molarity of solution = 0.540 M

Solution:

First of all we will calculate the number of moles of sodium hydroxide.

Number of moles = mass/molar mass

Number of moles = 12.5 g / 40 g/mol

Number of moles = 0.3125 mol

Volume of NaOH:

Molarity = number of moles / volume in L

Now we will put the values.

0.540 M = 0.3125 mol / volume in L

volume in L = 0.3125 mol / 0.540 mol/L

volume in L = 0.58 L

D( )-Camphor is treated with 5-methoxytryptamine in the presence of sodium cyanoborohydride to generate a new molecule, as a sin
Svetach [21]

The reducing agent can approach the carbonyl face of camphor by forming a one carbon bridge (known as an exo attack) or a two carbon bridge (termed endo).

The two resultant stereoisomers are known as isoborneol and borneol (from exo attack) (from endo attack). Gas chromatography (GC) analysis may be used to calculate the ratio of each isomeric alcohol in the mixture. Unfortunately, IR analysis does not permit this.

The stereochemistry of the reaction is regulated in stiff cyclic compounds like camphor and norcamphor by protecting one side of the carbonyl group from the reagent's assault. The hydrogen atom is added to the endo side, creating the exo alcohol isoborneol, while the methyl groups on the one-carbon bridge of camphor screen the approach of the hydride from the "top" or exo side of the two-carbon bridge. You will be asked to guess the main isomeric alcohol created by the norcamphor hydride reduction later in the lab report.
