An empirical formula is a molecular formula D. reduced to the ratio of atoms involved.
An empirical formula has simplefied ratios, which makes it easier to work with. However, the accuracy is not that good
hope this helps
Answer:
When it's gradient decreases
To determine the concentration of [H+] ions in the solution, it is important that we know the dissociation reaction of the solute. For this case, it would be
HNO3 = H+ + NO3-
Therefore, there is 1:1 ratio between HNO3 and H+ ions. The concentration of the ions would be the same as the solute which is 1.0x10^-4 M.
Answer:
vascular plants have that absorb the water and mineral from the air
Answer:
protons = 9
neutrons = 10
electrons = 9 because it is neutral atom
Explanation:
atomic number= protons = 9
atomic mass= protons + neutrons
19= 9 + n
n= 10
