Answer: The Taiga Forest
Explanation: I just took the test on e2020
M(O)= 16 g/mol
M(H)=1 g/mol
m(O)/m(substance)
1) 16/17
2)16/18
3) 16/19
4) 32/34=16/17
1) and 4) give the same answers, and 16/17 are the greatest fraction, so greatest % oxygen by mass also.
The answers should be 1) and 4).
1.6 X M is the [H] in a HC102 solution that has a pH of 3.78.
Explanation:
Given:
pH of the acid = 3.78
[H+] ion concentration = ?
The dissociation of the acid is shown as:
+ ⇔ HClO2
however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.
pH is calculated by applying the formula:
pH = - log [H+]
To calculate the H+ ion concentration the equation will be expressed as:
[H+] =
=
= 1.6 X M
The concentration or molarity of the Hydrogen ion in the solution of the acid is 1.6 X M.
A moon would be the correct answer.
D. sensory neurons-> interneurons in spinal cord-> motor neurons. I did my research
