Answer:
Explanation:
Here, we want to write the chemical reaction
step 1:
we start by writing the reaction between iron and oxygen
We have this as:

step 2:
Now, we want to predict the product as follows:

step 3:
We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:
This is a combination reaction. Look at the 2 elements on left and a compound on the right.
8.43
58.44g/mol*1/6.93g= 8.43moles of NaCL
500 grams Calcium Nitrate to mol= 3.04715
