Iron (III) oxide reacts with carbon monoxide producing iron metal and carbon dioxide. How much grams of iron is produced from 749 g of iron (III) oxide

389.48g of Fe

Explanation:

This is a stoichiometric reaction. First write a balanced equation of reaction: Fe2O3+3CO==>2Fe+3CO2

Since Fe2O3 and Fe are concerned with, calculate there masses in the balanced equation

Taking Molar mass of Fe and O to be 26 and 16 respectively.

Fe2O3 = (2×26) + (3×16)

=100g/mol

2Fe = 2×26

= 52

Therefore 100g of Fe2O3 gave 52g

749g of Fe2O3 will give

749×52/100

= 389.48g of Fe

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
