Answer : The balanced chemical reaction will be,

Fe_2O_3+3CO\rightarrow 2Fe+3CO_2

The coefficient of CO is, 3

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The unbalanced chemical reaction is,

Fe_2O_3+CO\rightarrow Fe+CO_2

This reaction is an unbalanced chemical reaction because in this reaction number of iron and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the Fe and the coefficient '3' put before the CO\text{ and }CO_2 we get the balanced chemical equation.

The balanced chemical reaction will be,

Fe_2O_3+3CO\rightarrow 2Fe+3CO_2

Thus, the coefficient of CO is, 3

Fe2O3+3CO----->2Fe+3CO2
so the coefficient of CO is 3

Calculate the number of molecules in 7 moles of oxygen
Alexxandr [17]

Answer:

4.21

Explanation:

use Avogadro's number

6.023 x 10^23

multiply this by 7 because you want to find 7 moles :

6.023 x 10^23 x 7 = 4.21

A cube of an unknown metal is 1.25 inches on each side and has a mass of 128.3741 g. What is its' density?
Mademuasel [1]
Hey there!

To find the density of an object, you must use this formula:
Density=Mass/Volume

Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.

Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125

Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392

Therefore, your density would be 65.7275392 grams per inches cubed.
