Answer:
Explanation:
a)
Even if a periodic table is not color coded, we can still find elements with the same chemical properties. This is easy because when we look at the group to find the elements, we see those that have similar chemical properties.
As an example, the Elements of group 1 forms basic oxides. This is a general chemical property of all group 1 elements.
b)
They have similar chemical properties because all the elements in any group has the same number of valence electrons.
c)
Lithium, Sodium and Potassium.
They're all elements of group 1, they all have 1 valence electron

Answer:
<em>The number of fish would decrease.</em>
Explanation:
Ecological hypoxia can be described as a condition in which the oxygen level drops to such low levels in the aquatic ecosystem that it is no longer able to support aquatic life. In such a condition, the number of fishes declines at a rapid rate because fishes require oxygen as an essential element. Also, those fishes which do not have better adaptations to survive might get totally wiped out from the aquatic ecosystem.
