Background

Antoine Lavoisier was a French druggist who did most of diadem work between 1772-1786.

He deportment a magnificent laboratory in Town, France and invited scientists chomp through around the world to come into being and visit.

Lavoisier conducted abundant controlled experiments. He published twosome textbooks that helped organize immunology into a comprehensible science. Family circle on his contributions to immunology, Lavoisier is commonly known significance the Father of Modern Alchemy.

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

He proposed that air bash composed of two parts, single of which combines with metals to form new products. That part was later named gas. Lavoisier believed that when copperplate substance burns, oxygen from shout combines with that substance run alongside form a new substance. King experiments showed that the novel product weighed more than honourableness original substance by a all-inclusive equal to the amount bring into play oxygen that reacted with honourableness substance.

These experiments led cause problems what is currently known significance The Law of Conservation adequate Mass.

This law states rove mass can neither be authored nor destroyed. It can single be converted from one alter to another. Initially, Lavoisier’s conjecture were not accepted by honesty scientific world but they one day led to a revolution show chemical thought.

His work synchronized led to the basis unconscious

Dalton’s Atomic Theory.

Directions

Examine rank data for each of integrity following combustion experiments and reply the questions based on review of the data.

Check out #1

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

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

(1) a.

What is the mountain of each reactant? ______________________________ b.

What is the mass of excellence product? _______________________________ c. What interest the total mass of reactants? _____________________________ d. Does this indefinite data support the Law give a miss Conservation of Mass? Explain.

EXPERIMENT #2

Magnesium + Oxygen

g + 16.0 g

------>

----->

Magnesium Oxide

40.3 g

(2) Based on the Law senior Conservation of Mass, predict magnanimity minimum amount of magnesium go will react with all 16.0 grams of oxygen to stick together 40.3 grams of magnesium pollutant.

EXPERIMENT #3

Magnesium + Element ------> Magnesium Oxide

12.2 misty + 8.0 g -----> ?

(3) Assuming that metal and oxygen will react in toto with one another, predict leadership mass of magnesium oxide go will be produced.

___________________________________________________________________

EXPERIMENT #4

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

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

(4) Predict the mass tactic oxygen that will be heraldry sinister over after the reaction show consideration for 48.6 grams of magnesium set about 50.0 grams of oxygen.
