A gas occupies 2.22 l at 3.67 atm. what is the volume at 1.94 atm?
Iteru [2.4K]
According to Boyle's law, volume is inversely proportional to pressure. thus P=k/V
Therefore PV=k
P1V1=P2V2
In the question above,
P1=3.67atm
P2=1.94atm
V1=2.22L
V2=?
Thus substituting for the values in the gas equation;
3.67atm*2.22L=1.94atm*V2
V2=3.67atm*2.22L/1.94atm
=4.21L

The hall reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron
AnnZ [28]

Answer: Iron gains electrons mean It is reduced

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Zn\rightarrow Zn^{2+}+2e^-

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Fe^{2+}+2e^-\rightarrow Fe

Thus iron gains electrons mean It is reduced

Balance the following chemical equation:<br><br> _Cr2O3+_Mg—&gt;_Cr+_MgO
Sergio [31]

Answer:

The answer to your question is Cr₂O₃  +  3Mg  ⇒   2Cr  +  3MgO

Explanation:

Data              

Unbalanced chemical reaction

               Cr₂O₃  +  Mg  ⇒   Cr  +  MgO

           Reactants        Elements       Products

                  2                      Cr                 1

                  3                       O                 1

                  1                        Mg               1

Balanced chemical reaction

               Cr₂O₃  +  3Mg  ⇒   2Cr  +  3MgO

           Reactants        Elements       Products

                  2                      Cr                 2

                  3                       O                 3

                  3                        Mg              3

Now the reaction is balanced
