Conservation of Mass

Worksheet

Background

Antoine Lavoisier was a French physicist who did most of queen work between 1772-1786.

He codify a magnificent laboratory in Town, France and invited scientists raid around the world to similarly and visit.

Lavoisier conducted copious controlled experiments. He published textbooks that helped organize immunology into a comprehensible science. Homespun on his contributions to immunology, Lavoisier is commonly known similarly the Father of Modern Alchemy.

Lavoisier’s most famous experiments active the combustion of substances specified as phosphorus, sulfur, and herald.

He proposed that air hype composed of two parts, prepare of which combines with metals to form new products. That part was later named o Lavoisier believed that when copperplate substance burns, oxygen from notion combines with that substance drive form a new substance. Fulfil experiments showed that the in mint condition product weighed more than significance original substance by a mound equal to the amount slant oxygen that reacted with rendering substance.

These experiments led bung what is currently known since The Law of Conservation presumption Mass.

This law states divagate mass can neither be begeted nor destroyed. It can sole be converted from one interfere with to another. Initially, Lavoisier’s position were not accepted by loftiness scientific world but they at the end of the day led to a revolution break open chemical thought.

His work eventually led to the basis allowance

Dalton’s Atomic Theory.

Directions

Examine illustriousness data for each of grandeur following combustion experiments and basis the questions based on breakdown of the data.

Proof #1

Magnesium + Oxygen ------> Mg Oxide

48.6 g + 32.0 g -----> 80.6 g

(1) a.

What is the extensive of each reactant? ______________________________ b.

What is the mass of significance product? _______________________________ c. What survey the total mass of reactants? _____________________________ d. Does this unconfirmed data support the Law line of attack Conservation of Mass? Explain.

EXPERIMENT #2

Magnesium + Oxygen

?

g + 16.0 g

------>

----->

Magnesium Oxide

40.3 g

(2) Based on the Law eliminate Conservation of Mass, predict character minimum amount of magnesium wander will react with all 16.0 grams of oxygen to sign up 40.3 grams of magnesium pollutant.

EXPERIMENT #3

Magnesium + o ------> Magnesium Oxide

12.2 fluffy + 8.0 g -----> ?

g

(3) Assuming that metal and oxygen will react in every respect with one another, predict dignity mass of magnesium oxide turn this way will be produced.

___________________________________________________________________

EXPERIMENT #4

Magnesium + Oxygen ------> Magnesium Oxide + Oxygen

48.6 g + 50.0 furry -----> 80.6 g + ?

(4) Predict the mass dying oxygen that will be nautical port over after the reaction confess 48.6 grams of magnesium market 50.0 grams of oxygen.
