The law of conservation of mass is a fundamental principle in chemistry that states that mass cannot be created or destroyed during a chemical reaction. In other words, the total mass of the reactants (substances that are being combined or broken down) must be equal to the total mass of the products (new substances that are formed).
Using this law, the scientist was able to predict that the reaction would produce 15.9 grams of copper sulfide. This prediction was based on careful measurements and calculations, taking into account the mass of the reactants and the stoichiometry (the ratio of the reactants and products) of the reaction.
By applying the law of conservation of mass, the scientist was able to confidently state that no mass would be lost or gained during the reaction. This principle is essential for accurately balancing chemical equations and understanding the overall composition of a reaction.
Overall, the law of conservation of mass is a critical concept that allows scientists to make predictions about the outcome of chemical reactions and ensures that mass is conserved throughout the process. It is one of the fundamental principles that underpin our understanding of the physical and chemical world. make this like a 8th grader wrote it
The law of conservation of mass is an important rule in chemistry. It says that mass can't magically appear or disappear during a chemical reaction. The total mass of the stuff that you start with (called reactants) has to be the same as the total mass of the stuff you end up with (called products).
A scientist used this law to figure out that a reaction would make 15.9 grams of copper sulfide. They measured and calculated things very carefully to make this prediction. They looked at how much stuff they started with and how the different things were supposed to combine.
Because of the law of conservation of mass, the scientist knew that no mass would go away or come out of nowhere during the reaction. This is important for making chemical equations balanced and knowing what's going on in a reaction.
Overall, the law of conservation of mass is a big deal in chemistry. It helps scientists make predictions about reactions and it makes sure that mass stays the same. It's one of the basic rules that helps us understand how things work in the chemical world.
