An electrically neutral molecule has the formula C3H4O2N. If the carbon atoms form the usual number of bonds, how many covalent

bonds will each hydrogen atom have with other atoms in the molecule?

Each hydrogen bond will  form ONE COVALENT bond with the other atoms in the molecule. Hydrogen has only one atom; to form a covalent bond, it has to donate one electron and the other atom that hydrogen is bonding with will donate one electron also, making two. These two electrons will be shared between the two, making the atoms to have two electrons each.

If 1/8 remains after 21 years, what is the half-life?
vagabundo [1.1K]

Half life formula

The number of unstable nuclei remaining after time t can be determined according to this equation:

N(t) = N(0) * 0.5^(t/T)

where:

N(t) is the remaining quantity of a substance after time t has elapsed.

N(0) is the initial quantity of this substance.

T is the half-life.

It is also possible to determine the remaining quantity of a substance using a few other parameters:

N(t) = N(0) * e^(-t/τ)

N(t) = N(0) * e^(-λt)

τ is the mean lifetime - the average amount of time a nucleus remains intact.

λ is the decay constant (rate of decay).

All three of the parameters characterizing a substance's radioactivity are related in the following way:

T = ln(2)/λ = ln(2)*τ

How to calculate the half life

Determine the initial amount of a substance. For example, N(0) = 2.5 kg.

Determine the final amount of a substance - for instance, N(t) = 2.1 kg.

Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.

Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.

If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.

Answer:

like DNA, RNA is made up of nucleotides.There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Explanation:

hope this helps :)

Question 8 (1 point)
Arlecino [84]

The term which best describes species C relative to species A is Sister

species. This is as a result of them sharing largest number of derived traits.

<h3>What is Ingroup?</h3>

Ingroup is defined as the group in which organism belongs to. We were

told that A and C are ingroup species.

Species A sharing the largest number of derived traits with species C

means that they have similar traits and a common parent which is a

characteristic of sister species.
