Please answer <3 how many moles of Cl2 must react to produce 11.4 g of AlCl3?

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added
