Answer:
The official measurement unit for energy is the Joule (J). Among the most common units measuring energy mention should be made of the kilowatt/hour (kWh), used especially for electric energy (in fact it is used to calculate electricity bills).
First calculate the moles of CsOH.
moles CsOH = 0.217 M * 0.005 L = 0.001085 mol
We need 1 mole of HI per 1 mole of CsOH, therefore the
moles of HI needed is:
moles HI = 0.001085 mol
The volume required is therefore:
Volume = 0.001085 mol / 0.550 M
<span>Volume = 1.97x10^-3 L = 1.97 mL</span>
I think it’s CTell me if I’m wrong
Answer:
O.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> O goes from 0 to -2, so, it is the element that is reduced.</em>
Oxidation is a process when an atom, a group of atoms, or an ion loses electrons.
For example,
Cu⁰ -------> Cu⁺² + 2e⁻. This is an oxidation process.
As we can see an oxidation number was 0, and it became +2. The oxidation number is increased. Oxidation number of the atom, when an atom has undergone oxidation, increases.
So, answer is b.False.
