Answer:

<em><u>The answer is</u></em>: <u>Hydroxides are substances that produce hydroxide ions in solution.</u>

Explanation:

Hydroxides result from the combination of a basic oxide with water, hydroxides are also known as bases. These compounds are substances that produce hydroxide ions in solution.

Aqueous solutions of hydroxides are basic, since they dissociate in the metal cation and hydroxide ions. This is so because the bond between the metal and the hydroxide group is of the ionic type, while the bond between oxygen and hydrogen is covalent.

<em><u>The answer is</u></em>: <u>Hydroxides are substances that produce hydroxide ions in solution.</u>

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.

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?
inn [45]

Answer:

Dominant

Explanation:

A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).

A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).
