What is the purpose of using chemical formulae in chemical equations?
What is the purpose of using chemical formulae in chemical equations?
- To represent a chemical reaction more concisely and effectively (correct)
- To make the equations longer and less useful
- To confuse students with complex symbols
- To increase the mass on both sides of the equation
How can you determine if a chemical equation is balanced?
How can you determine if a chemical equation is balanced?
- By comparing the length of the equation on both sides
- By analyzing the color of the compounds in the reaction
- By reviewing the number of atoms of each element on both sides (correct)
- By counting the words used in the equation
What does the law of conservation of mass state regarding balanced chemical equations?
What does the law of conservation of mass state regarding balanced chemical equations?
- The mass increases on both sides of the equation in a balanced chemical reaction
- The total mass of the elements in the products is equal to the total mass in the reactants (correct)
- The mass decreases on both sides of the equation in a balanced chemical reaction
- The total mass of the elements in the products is not equal to the total mass in the reactants
