There are several ways to model a compound. one type of model is shown. 4 c's are connected in a line by 3 black lines. the c on the left has 3 h's attached to it each by a black line. the next c has 1 h attached by a black line and 1 o attached by 2 black lines. the next c has 2 h's attached to it by 1 black line each. the last c has 2 h's attached to it by 1 black line each and 1 o attached by a single black line. that o has an h attached to it by 1 black line. what is the chemical formula for the molecule represented by the model? cho c4h9o2 c4h8o c3h8o2

Answer : The chemical formula for the molecule is

Explanation :

Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.

In the structural formula, the lines are used between the atoms.

As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.

Thus, the chemical formula for the given molecule will be,

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
