Answer:
The answer is
<h2>5.43 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 250 g
volume = 46 mL
The density is
We have the final answer as
<h3>5.43 g/mL</h3>
Hope this helps you
Answer:
pOH = 9.
Explanation:
The inverse relationship between the pH and pOH of any given solution can be written as:
pH = 14 - pOH
Or conversely:
pOH = 14 - pH
With the above information in mind we can <u>use the given pH to calculate the pOH</u>:
pOH = 14 - pH
pOH = 14 - 5
pOH = 9
Thus, black coffee has a pOH of 9.
Explanation:
After the electron configuration, the last shell of the beryllium atom has two electrons. In this case, both the valence and valence electrons of beryllium are 2. We know the details about this. The elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation.
I belevieve the answer is A
