When heated, lithium reacts with nitrogen to form lithium nitride: 6li(s) + n2(g) → 2li3n(s). a) what is the theoretical yield of li3n in grams when 12.3 g of li is heated with 33.6 g of n2? b) if the actual yield of li3n is 5.45 g, what is the percent yield of the reaction?

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
