A + BC ---> AB + C
So here one reactant (A) is accepting a group which is being given by another compound (BC) however the A is not giving any group / element or ion
So this single displacement
Similarly in the given reaction
the anion OH- is only being replaced
The element Ca accepts OH- and H2O loses the same group to form new element H2
So the correct answer is
Single replacement also known as single displacement.
The electronic configuration of sulfur is expressed as:
1s^2 2s^2 2p^6 3s^2 3p^4
At the 3p sublevel,
principal quantum no - 3
<span>angulum quantum no - 1
</span><span>magnetic quantum no - (-1), 0, (-1)
spin quantum no - (+1/2), (-1/2)</span>
The set of quantum numbers would be:
[ 3 , 1, -1 , +1/2 ] or [ 3 , 1, -1 , -1/2 ]
<span>[ 3 , 1, 0 , +1/2 ] or [ 3 , 1, 0 , -1/2 ]
</span><span>[ 3 , 1, 1 , +1/2 ] or [ 3 , 1, 1 , -1/2 ]</span>
Balancing redox reactions:
Oxygen should be balanced by adding as needed, while hydrogen should be balanced by adding .
What is a redox reaction?
Redox reactions, also known as oxidation-reduction reactions, involve the simultaneous oxidation and reduction of two different reactants.
The Half-Equation Method is one technique used to balance redox processes. The equation is divided into two half-equations using this technique: one for oxidation and one for reduction.
By changing the coefficients and adding , , and in that order, each reaction is brought into equilibrium:
- By putting the right number of water () molecules on the other side of the equation, the oxygen atoms are brought into balance.
- By adding ions to the opposing side of the equation, one can balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom).
- Total the fees for each side. Add enough electrons () to the more positive side to make them equal. (As a general rule, and are nearly always on the same side.)
- The on either side must be made equal; if not, they must be multiplied by the lowest common multiple (LCM) in order to make them equal.
- One balanced equation is created by adding the two half-equations and canceling out the electrons. Additionally, common terms should be eliminated.
- Now that the equation has been verified, it can be balanced.
