What does the Law of Conservation of Mass tell us?
Mass of the reactants is equal to the mass of the products in a closed system.
200

How many atoms are in the molecule: C6H12O6

6 C + 12 H + 6 O = 24 atoms

What is the difference between Iron (II) oxide and Iron (III) oxide?

Iron (II) oxide is made using the Fe 2+ ion, and Iron (III) oxide is made using the Fe3+ ion.

400
Turn this chemical equation into a word equation: FeO + NaCl --> FeCl2 + Na2O
iron (II) oxide and sodium chloride makes (produces or yields) iron (II) chloride and sodium oxide.
