The answer is D: studying how the mayfly population affects the number of trout in a stream <span> As the science of ecology studies interactions between individual organisms and their environments.</span>
The number 16 next to the elemental symbol of Nitrogen
which is N indicates the mass number of the element. Now the atomic number of N
is 7, this is also equal to the number of protons or electrons in the nucleus. So
the balance is 16 – 7 = 9 which is being occupied by the neutrons. Therefore
the number of neutrons is:
<span>9</span>
Answer:
The cis-trans isomerism (or geometric isomerism ) is a type of stereoisomerism of alkenes and cycloalkanes . A distinction is made between the cis isomer , in which the substituents are on the same side of the double bond or on the same face of the cycloalkane. This is an electronic version in English. [ 1 ]
Their characteristics are:
They both have the same formula.They have different chemical and physical properties.The IUPAC advises against the use of the term geometric isomerism. [ 2 ]
