Define the Law of Conservation of Mass.
It involves mass measurements in reactions.
Provide an example of the Law of Definite Proportions.
Think about water's chemical formula.
What does the Law of Conservation of Mass state?
Think about what happens to mass in reactions.
Is the following statement true or false? 'The Law of Definite Proportions states that the proportion of elements varies based on the reaction conditions.'
Consider the chemical formula of compounds.
In a closed system, 5 g of hydrogen reacts with 8 g of oxygen. Calculate the mass of water produced and confirm conservation of mass.
Think about the combination of masses.
If 2 moles of gas A react with 1 mole of gas B, how many moles of gas C will be produced, if 1 mole of gas C represents two moles of gas?
