3; Double Displacement

Explanation:

Balancing is making the number of atoms of each element same on both the sides (reactant and product side).

To find the number of atoms of each element we multiply coefficient and the subscript

For example 5Ca_1Cl_2 contains

5 × 1 = 5 ,Ca atoms and

5 × 2 = 10, Cl atoms

If there is a bracket in the chemical formula

For example 3Ca_3 (P_1 O_4 )_2 we multiply coefficient × subscript × number outside the bracket to find the number of atoms

(Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )

3 × 3 = 9 , Ca atoms

3 × 1 × 2 = 6, P atoms

3 × 4 × 2 = 24, O atoms are present

Let us balance the equation given

Ca_3 N_2+6H_2 0Ca(OH)_2+2NH_3

(UNBALANCED)

Reactant side Number of atoms or groups Product side

of each element

3 Ca 1

2 N 2

12 H 8

6 O 2

Multiplying Ca(OH)_2 on the right side by 3, we will have

Ca_3 N_2+6H_2 03Ca(OH)_2+2NH_3

Reactant side Number of atoms or groups Product side

of each element

3 Ca 3

2 N 2

12 H 12

6 O 6

Balanced

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
