It will be K-potassium because when you go down a group the electronegativty gets bigger while when you go across the period they get smaller because of the valence electrons. Group 8 has the lowest electronegativty because they have a full outer shell. From left to right on the periodic table it decreases but from top to bottom it increases.
In order to compute mean, you have to add all values of the data set up and divide by the number of data values there are.
In this case, the total sum of all data values is: 81+88+69+65+87=390
The number of data values is 5
To compute mean: 390/5=78
The mean height of the corn stalks is 78cm (C)
Answer:
<h2>12.38 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
m is the mass
v is the volume
From the question
m = 149.8 g
v = 12.1 mL
We have
We have the final answer as
<h3>12.38 g/mL</h3>
Hope this helps you
