First laid down by Jeremias Benjamin Richter.

Question 2

What do the coefficients in Stoichiometry indicate?

Question 3

When hydrogen gas and oxygen gas r mixed and exploded, the product is __

Answer 3

Gaseous water

Question 4

What does Avogadro’s hypothesis state regarding gases, temp, pressure, and moles?

Answer 4

Equal volumes of gases at the same temperature and pressure contain an equal # of moles.

Question 5

What is the Law of Combining Volumes and who discovered it?

Answer 5

The volumes of gases involved in chemical reactions measured at the same temp and pressure r in the same ratio as their coefficients in the balanced equation.
Proposed by Gay-Lussac in 1808

Answer 6

Is fundamental to the production of many fertilizers, used to produce ammonia from hydrogen and nitrogen.
