89,6 g ammonia are obtained.
51.4 - 51.8
Urea is an organic compound. Its chemical formula is CO parenthesis NH2 and 2 on the outside. The molar mass is 60.06 grams per mol.
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
92.4 grams
384.5g
The mass of ammonia is 147,5 g.
This oxide may be CdO.
110 g ammonia are produced.
76 g ammonia are obtained.
89,6 g ammonia are obtained.
51.4 - 51.8
62.1 - 62.5
trick question guys, there is none. this question should be deleted for such stupidity. FOOCK CHEMISTRY!
Balanced equation. Mg + H2SO4 -> MgSO4 + H2 ------------------------------------- ( sufuric acid in excess---magnesium limits, drives reaction ) 24 grams magnesium (1 mole Mg/24.31 g)(1 mole H2/1 mole Mg)(2.016 g/1 mole H2) = 1.9 grams of hydrogen gas produced ( can call it 2.0 grams ) --------------------------------------------------
Balanced equation first. N2 + 3H2 >> 2NH3 (hydrogen is limiting and drives the reaction ) 3.41 grams H2 (1mol/2.016g )(2mol NH3/3mol H2 )(17.034g NH3/1mol NH3 ) = 19.2 grams of ammonia produced ( this is called the Born-Haber process )
71/284 = x / 4 x = 1 mole
