The complete balanced chemical reaction is:

<span>C7H16  +  3O2  -->  7CO2  +  8H2O</span>

 

So 3 moles of oxygen O2 is required for every 1 mole of C7H16. In the same manner, 3 molecules of O2 is required for every 1 molecule of C7H16.

 

Answer:

<span>3 molecules O2 </span>

Gravel is being dumped from a conveyor belt at a rate of 40 ft3/min, and its coarseness is such that it forms a pile in the shap
ikadub [295]

The height is increasing at the rate of (6/5π) ft/min.

It is given that Gravel is being dumped from a conveyor belt at a rate of 40 ft3/min. Also, its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal.

For this, we need to find the volume of a cone. Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

The volume of a cone is - V=1/3hπr²

Find the quotient. x + 7 x ÷ 9 x
kicyunya [14]
The first step for solving this expression is to write the division as a fraction.
x + \frac{7x}{9} × x
Calculate the product.
\frac{7x X x}{9}
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
\frac{7 x^{1}X x^{1}  }{9}
Now multiply the terms with the same base by adding their exponents.
\frac{7 x^{1+1}}{9}
Finally,, add the numbers together to get your final answer.
x + \frac{7 x^{2}}{9}
Let me know if you have any further questions.
