Answer:
pH= 3.30
Explanation:
Hydrochloric acid is a strong acid that completely dissociates in water.
For a 0.00050 M HCl solution the concentration of the hydrogen ions, [
H
+
]
, is 0.00050 moles/liter (i.e. 0.025 M).
The pH is defined as −
log
[
H
+
]
.
Substituting 0.00050 into the equation for pH we find that the 0.00050 M HCl solution has a pH of -log(0.00050) = 3.30.
Answer:
3Fe(s)+2O2(g)---->Fe3O4
this way you will have 3irons on both sides and 4 oxygens.
I hope this helps
Answer:
B. Aromatic
Explanation:
Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.
For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
