Lithium and nitrogen react to produce lithium nitride: 6li + n2 --> 2li3n how many moles of n2 are needed to react with 0.500 mol of lithium?

How many atoms are there in 5.70 mol of mg

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
