Balance the following reaction in KOH (under basic conditions). What are the coefficients in for C3H8O2 and KMnO4 in the balance
GrogVix [38]

Answer:

Coefficient of C_3H_8O_2=3

Coefficient of KMnO_4=8

Explanation:

We are given that  a reaction in which C_3H_8O_2 reacts with KMnO_4

We have to find the coefficient of each reactants in balanced reaction

3C_3H_8O_2(aq)+8KMnO_4(aq)\rightarrow 3C_3H_2O_4K_2(aq)+8MnO_2(aq)+2KOH+8H_2O

Coefficient is defined the constant  value multiplied with a reactant in a reaction.

Coefficient of C_3H_8O_2=3

Coefficient of KMnO_4=8

Coefficient of C_3H_2O_4K_2=3

Coefficient of MnO_2=8

Coefficient of H_2O=8

Coefficient of KOH=2

Hence, Coefficient of C_3H_8O_2=3 and coefficient of KMnO_4=8

In what order do electrons fill orbitals within the 3p sublevel? Electrons don’t fill orbitals; protons and neutrons fill orbita
lorasvet [3.4K]

 The order  do electron fill  orbitals within the 3p sublevel  is that they spread  out, waiting  until each orbital  has one electron before  doubling  up.


<u><em>Explanation</em></u>

<u> </u> According    to   hund's  rule  every orbital in a   subshell  is singly  occupied  with  one  electron before  any one orbital  is  doubly  occupied,and  all electrons  in   singly occupied  orbital have the same spin.

when every orbital  in a subshell is   singly  occupied by electrons it is then  doubled, and the two electrons  in same orbital  have  opposite spins
