Answer:
[H3O+] = 1.0*10^-12 M
[OH-] = 0.01 M
Explanation:
We can use the following equation to find the hydronium ion concentration. Plug in the pH and solve for H3O+.
pH = -log[H3O+]
<u>[H3O+] = 1.0*10^-12 M</u>
Now, to find the hydroxide ion concentration we will use the two following equations.
14 = pH + pOH
pOH = -log[OH-]
14 = 12 + pOH
pOH = 2
2 = -log[OH-]
<u>[OH-] = 0.01 M</u>
population is the number of species living in a given area if this is regarding biology or earth studies :)
B. the periodic law
Explanation:
The periodic law was not explained by the Dalton's atomic theory.
The periodic law was first postulated by Dimitry Mendeleef and Lothar Meyer around 1869 where they independently arrived at the periodic table or chart.
- The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- The modern periodic law was restated by Henry Moseley in the early 1900s. He changed the basis of the law to atomic number.
- The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".
The laws of conservation of mass, multiple proportions and definite proportions are all explained by the Dalton's atomic theory.

Explanation:
The equation doesn't satisfy the Law of Conservation of Matter because There are more oxygen atoms after the reaction than there were before the reaction.
Therefore,
