Answer:
One may conclude that they have an identical number of electrons in their outermost shell, therefore the can be substituted for one another.
Explanation:
Elements in the same family tend to behave similarly in chemical reactions because they have similar number of valence electrons in their outermost shell and they also have similar chemical properties.
Valence electrons are responsible for reactions between elements. The valence electron makes it possible for atoms to combine and react, therefore, elements in a family behave similarly in chemical reactions because they have an identical number of electrons in their outermost shell.
Explanation:
When designing and conducting a scientific experiment then it is necessary to sequentially follows all the steps necessary for the experiment.
Also, it is required to identify independent variables, if any. On the other hand, it is required to address any confounding variables, so that it becomes mentioned the type or number of variables present.
Thus, we can conclude that when designing and conducting a scientific experiment:
- Identify the independent variable.
- Address any confounding variables.
<span>The correct answer is Na+, reduction is the gaining of electrons by ions, the ease at which an ion or an atom gains electrons depends on its position in the electrochemical series. Electrochemical series arranges atoms of elements in order, based on the ease of gaining electrons. In this case, Na+ can easily gain electrons compared to the other ions given. We can also look at it based on the electromotive force of each (EMF); +0.77 Vb. -0.25 Vc. -2.71 Vd. +0.15; this evidently shows that Na+ can undergo reduction easily compared to the other ions</span>
Answer:
Hexane is a 6-carbon hydrocarbon.
Cyclopentyl is a 5-carbon, hydrocarbon ring.
The 1- indicates that the cyclopentyl is attached to the first carbon in hexane.
Two ways of drawing the structure of 1-cyclopentylhexane are below:
