Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
In the context of the law of conservation of mass, what specifically occurs to the atoms of the reactants during a chemical reaction?
Which of the following is the primary reason why Antoine Lavoisier is credited with clearly demonstrating the law of conservation of mass?
A student reacts of calcium carbonate with of hydrochloric acid in an open beaker. If of carbon dioxide gas escapes into the air, what is the final mass of the solution remaining in the beaker?
When iron reacts with oxygen in the air to form rust (), the mass of the rust is greater than the mass of the original iron. This occurs because the iron has:
If a magnesium ribbon is burned in an open crucible, the mass of the resulting white powder (magnesium oxide) is found to be greater than the mass of the original magnesium. This is because:
True or False: In a balanced chemical equation, the sum of the coefficients of the reactants must always be equal to the sum of the coefficients of the products.
Antoine Lavoisier was able to provide experimental evidence for the conservation of mass in the 18th century by carefully __________ both the reactants and products of reactions.
In the following unbalanced equation, which specific atom count is currently unequal between the reactants and the products?
In an open system where a reaction produces a gas, why does the 'missing mass' not actually violate the law of conservation of mass?
The law of conservation of mass states that in a chemical reaction, mass is neither __________ nor destroyed.
