Thorium-234 has a half life of about 25 days. What percent of the thorium will remain after 125 days
solong [7]

Answer:

3.125% will remain after 125 days

Explanation:

Given data:

Half life of Th-234 = 25 days

Percent of thorium remain after 125 days = ?

Solution:

Number of half lives = T elapsed / half life

Number of half lives = 125 days / 25 days

Number of half lives = 5

At time zero =100%

At 1st half life = 100%/2 = 50%

At second half life = 50%/2 = 25%

At third half life = 25%/ 2 = 12.5%

At 4th half life = 12.5% /2 = 6.25%

At 5th half life = 6.25% /2 = 3.125%

1) Compounds Y and Z both have the formula C9H18.
sashaice [31]

Answer:

See explanation and images attached

Explanation:

We know that the cis isomer has more heat of hydrogenation since it is less stable than the trans isomer. Since the hydrogenation of both compounds yields the same product and the hydroboration/oxidation both give a primary alcohol, they are geometric isomers and Y is the trans isomer (Image 2).

For the compound C8H12, the compound in question must be 1,5- cyclooctadiene since two moles of the same aldehyde was obtained after ozonolysis and reaction with two equivalents of hydrogen gives cyclooctane (Image 1).

How does monochlorination work? Please describe with an exampel.
Sunny_sXe [5.5K]

We have to explain monochlorination.

Monochlorination is the process to introduce one chlorine atom in any organic compound.

Generally, monochlorination takes place by replacement of proton from organic compound. To do chlorination, Cl₂ or HCl is used as reagent.

Inntroduction of  one Cl-atom in any organic molecule takes place through free radical mechanism.

The monochlorination of benzene is shown here:
