pls answer A&B # Law of Conservation of Mass## ExplanationMatter is neither created nor destroyed in a chemical reaction. Thus, the mass of the products of a chemical reaction must be equal to the mass of the starting materials. Formally, this concept is called the **law of conservation of mass**.## Example Problems### Problem AA sample of sodium reacts completely with 0.497 kg of chlorine, forming 819 g of sodium chloride. What mass of sodium reacted?- **Task:** Express your answer to three significant figures and include the appropriate units.- **Tools:** - View Available Hint(s) [Expandable Section] - Input Box for Value and Units - Submit Button### Problem BWhen carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 15.6 g of carbon were burned in the presence of 59.2 g of oxygen, 17.6 g of oxygen remained unreacted. What mass of carbon dioxide was produced?- **Task:** Express your answer to one decimal place and include the appropriate units.- **Tools:** - View Available Hint(s) [Expandable Section] - Input Box for Value and Units - Submit Button### Navigation Options- Review- Constants- Periodic Table(End of Content)
