i was just wondering, do i need to wrap an aluminum foil around the cookie sheet?and THEN put the dough inside the oven to bake??
the question is what caused the smoke alarm to go off ? was it the sugar in the cookies burning ? (turning slightly black) - indicative of improper temperature or overcookingcheck your oven temperatures - you may need to recalibrate your ovenwas it the butter or spray on shortening ? (residual non-stick agents will burn if left on the cookie sheet - and will smoke) - suggest you clean off the cookie sheet between cookie batches, wipe down with a semi-dry paper towelSmoke alarm fix - you could always pull the battery or cover it with a Tupperware containerJUST REMEMBER TO REVERSE THIS PROCESS WHEN YOU ARE DONE.
a millionbalanced equation is 2NH3 + 3/2O2 - N2 + 3H2O so there is a million.5 moles O2 (or in case you multiply by using 3 there are 4.5 moles O2) so the answer is c2.balanced equation is Mg +2HCl - MgCl2 +H2 so comparing moles 1mole Mg : 2moles HCl 2.5mols Mg ought to provide 5moles HCl So the answer to ais 5 x gfm of HCl (a million + 35.5) 5x36.5 182.5g bstudy moles so 1mole Mg : 2moles HCl : 1mole MgCl2 : 1mole H2 2.5moles : 5 moles : 2.5moles : 2.5 moles mass of each product (mgCl2) 2.5 x gfm of MgCl2 ( 23.3 +70) 2.5 x ninety 3.3 233.25g mass of H2 2.5 x gfm of H2 (2) 2.5 x 2 5g answer to bmass of MgCl2 233.25g, mass of H2 5g
