Answer:
In the criss-cross method, the numerical value of the ion charge of the two atoms are crossed over, which becomes the subscript of the other ion. Using this technique, we will write the chemical formula of the given compounds.
Criss cross the absolute values to give Al2O3. To find the formula for magnesium oxide:- The oxidation number of Mg is +2 and oxygen is -2. Criss cross the absolute values to give Mg2O2In this example there is a common factor of 2 so divide by 2 to give MgO.
Answer:
8.00 moles.
Explanation:
The ratio of Fe to FeO is 2:2 = 1:1, so 8 moles are produced.
The coefficient for the chemical formula 3CO2 is the 3.
