One in a series of reactions that inflate air bags in automobiles is to decomposition of sodium azide (NaN.).
2NaN,(5) - 2Na(s) + 3N, (g)
Determine the mass of Ny produced if 100.0 g NaN; is decomposed.

Aluminum–lithium (al-li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. a commercial aircraft skin material having a density of 2.47 g/cm3 is desired. compute the concentration of li (in wt%) that is required.

What is the chemical formula of the following compound

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende
