Answer:
15
Explanation:
Because the ratio of copper in the solution is 15
Answer:
'Oxidation states have changed.'
Explanation:
Redox Reactions can be identifiable by a change in oxidation number/states of two of the atoms in the reaction. Any reaction in which no oxidation numbers/state change is not a redox reaction.
Answer:
Explanation:
the strength and vitality required for sustained physical or mental activity.
hi
Thus, a sodium hydroxide solution has a greater OH– concentration than the same concentration solution of NH3. At the same concentrations, the pH of the NaOH solution is greater (more basic) than the NH3 solution.
Answer:
HOCl is the preferred arrangement.
Explanation:
Hypochlorous acid (HOCl or HClO) is a weak acid that contains Hydrogen, Chlorine and oxygen. Generally both are accurate molecular formulars as hey show the exact number of atoms of elements present in the compound.
However the preferred formular is HOCl. The reason for this is because HOCl implies the molecular structure (that is, how the atoms are bonded to each other). The H is bonded to the O and the O in turn is being bonded to the Cl. HClO on the other hand says nothing about the molecular structure.
