When a 16.50 g sample containing nickel and oxygen is analyzed, 5.87 g of nickel are found. What is the percent composition of t
Virty [35]

Answer:

\%O=64.2\%\\\\\%Ni=35.8\%

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to tell that since the total mass is 16.50 g and 5.87 g correspond to nickel, then the mass of oxygen is:

m_O=16.50g-5.87g=10.63g

And therefore, the resulting percent composition turns out to be:

\%O=\frac{10.60}{16.50} *100\%=64.2\%\\\\\%Ni=\frac{5.87}{16.50} *100\%=35.8\%

Regards!

Identify the following reaction as oxidation and reduction F2(g)+2e-/2F-(aq)​
sertanlavr [38]

Answer:

Reduction

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

In given reaction fluorine gas gain two electron and form fluoride ions.

F₂(g) + 2e⁻    →   2F⁻(aq)

The given reaction is reduction because oxidation state is decreased from zero to -1.
