Calculate the number of grams of fe2o3 needed to react with 19.0 g c.

The mass of iron (III) oxide needed to react is 67.4 g

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of carbon = 19.0 g

Molar mass of carbon = 12 g/mol

Putting values in equation 1, we get:

The chemical equation for the reaction of iron (III) oxide and carbon follows:

By Stoichiometry of the reaction:

3 moles of carbon reacts with 2 moles of iron (III) oxide

So, 1.58 moles of carbon will react with = of iron (III) oxide

Now, calculating the mass of iron (III) oxide by using equation 1, we get:

Molar mass of iron (III) oxide = 159.70 g/mol

Moles of iron (III) oxide = 0.422 moles

Putting values in equation 1, we get:

Hence, the mass of iron (III) oxide needed to react is 67.4 g

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
