the stability of the radioactive element
Explanation:
The stability of a radioactive element can influence the rate of nuclear decay reaction. Pressure, temperature and concentration only affects chemical changes. These factors would not have any effect on radioactive decay of an element.
- Every atomic nucleus have a specific neutron/proton ratio which ensures the stability of the nucleus.
- Any nucleus that deviates from the stability ratio will continue to split until it achieves stability.
- The more unstable a nucleus is, the faster it decays.
- This is the basis of radioactive decay of elements.

Answer:
a > c > b
Explanation:
As higher is the strength and stiffness of the bond between two atoms, more stable it is, and more difficult is to these bonds vibrate. So, the stretching vibration decreases when the strength and stiffness increases.
As more bonds are done between the atoms, more strength, and stiffness they have. So, the order of increase is:
simple bond > double bond > triple bond
And the increased frequency of vibration is:
triple bond > double bond > simple bond
An alkane is a hydrocarbon that has only simple bonds between carbons, an alkene is a hydrocarbon with one double bond between carbon, and an alkyne is a hydrocarbon with one triple bond. So, the increase in vibration of them is:
alkyne (a) > alkene (c) > alkane (b)
Answer:
C is the reaction intermediate.
Explanation:
A reaction intermediate is a molecular structure that is formed during the reaction but then is converted in the final products.
Usually, these reaction intermediates are unestable and, for that reason, the lifetime of these structures is low.
In the reaction, you can see in the first step C is produced, but also, in the second step reacts producing D. As is produced and, immediately consumed,
<h3>C is the reaction intermediate.</h3>
The car has greater momentum because it has more mass than a bike, even if they have the same speed. I hope this helped! :-)
Fluoride, a naturally occurring mineral, helps prevent cavities and can even reverse the earliest stages of tooth damage. Because of its benefits for teeth, fluoride is added to many public water supplies. It's also a common ingredient in toothpaste and mouth rinses
