​

Bauxite is the ore of aluminium.

Bauxite is the ore of aluminium.The ore aluminium is the world's primary sources of aluminum. The ore must be chemically processed to produce alumina (aluminum oxide).

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

the ratio of the conjugate base to the acid required to attain the desired ph.
