Answer from: izzynikkie

The balanced equation is $2H_2+O_2\rightarrow 2H_2O$

Explanation:

A balanced chemical equation always follow law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

For the given options:

Option 1:

The given chemical equation follows:

$H_2+O_2\rightarrow H_2O+O_2$

There are 2 atoms of hydrogen and 2 atoms of oxygen on the reactant side. There are 2 atoms of hydrogen and 3 atoms of oxygen on the product side.

As, total number of individual atoms are not equal on both the sides of the reaction. So, the reaction is not balanced.

Option 2:

The given chemical equation follows:

$2H_2+O_2\rightarrow 2H_2O$

There are 4 atoms of hydrogen and 2 atoms of oxygen on the reactant side. There are 4 atoms of hydrogen and 2 atoms of oxygen on the product side.

As, total number of individual atoms are equal on both the sides of the reaction. So, the reaction is balanced.

Option 3:

The given chemical equation follows:

$H_2+O_2\rightarrow H_2O$

There are 2 atoms of hydrogen and 2 atoms of oxygen on the reactant side. There are 2 atoms of hydrogen and 1 atom of oxygen on the product side.

As, total number of individual atoms are not equal on both the sides of the reaction. So, the reaction is not balanced.

Option 4:

The given chemical equation follows:

$4H_2+O_2\rightarrow H_2O+O$

There are 8 atoms of hydrogen and 2 atoms of oxygen on the reactant side. There are 2 atoms of hydrogen and 2 atoms of oxygen on the product side.

As, total number of individual atoms are not equal on both the sides of the reaction. So, the reaction is not balanced.

Hence, the balanced equation is $2H_2+O_2\rightarrow 2H_2O$

Answer from: Quest

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
