Conservation of Mass
Cards in this deck (5)
- 1State the law of conservation of massIn a chemical reaction, the total mass of the products is equal to the total mass of the reactants
- 2Why must a symbol equation balance?Mass is conserved because no atoms are made or lost
- 3Calculate the relative formula mass of water (h20)h=1
o=16
1+1+16=18
Mr=18 - 4Calculate the relative formula mass of calcium carbonate (CaCO3)Ca=40
C=12
O=16
16+16+16+12+40=100
Mr=100 - 5When iron is burned, iron oxide is produced and the mass of the solid increases. why does the mass of the solid increase?The mass of the solid increases because when the iron is burned, it combines with the oxygen and the oxygen has mass
