Answer:
Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.
Explanation:
For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.
When you put water onto water, it's an addition of water, you don't say it's wet or wetter.
Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.
Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.
So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
Answer:
Diversity of the community = 2.097
Explanation:
Given:
Number of pitch pines = 134
Number of douglas firs = 24
Number of red pines = 53
Find:
Diversity of the community
Computation:
Simpson's diversity index = N(N-1)/Σn(n-1)
Particular n n(n-1)
Pitch pine 134 17822
Douglas firs 24 552
Red pine 53 2756
Total N=211 21130
So,
D= [211(211-1)] / 21130
D = 2.097
Diversity of the community = 2.097
<u>Answer:</u> The mass of chlorine atom required to combine is 35.5 grams.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of sodium = 23 g
Molar mass of sodium = 23 g/mol
Putting values in equation 1, we get:
According to mole concept:
1 mole of an atom contains 
number of particles
So, 1 mole of sodium will contain = 
number of atoms
Number of atoms of chlorine = Number of atoms of sodium = = 1 mole
Now, calculating the mass of chlorine required by using equation 1:
Moles of chlorine = 1 mole
Molar mass of chlorine = 35.5 g/mol
Putting values in equation 1, we get:
Hence, the mass of chlorine atom required to combine is 35.5 grams.
