Nitrogen reacts with a metal to form a compound in which there are three atoms of the metal for each atom of nitrogen. if 1.486
g of the metal reacts with 1.000 g of nitrogen, what is the calculated atomic mass of the metal?
use your calculated atomic mass to identify the metal. (for your answer, input the proper chemical symbol for element x.)

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
