Hey,I'm in the 8th grade and we had to bake something, I chose cupcakesMy question being, what are 4 chemical reactions that occur in the cupcake making process? (This is from opening the box to icing them.) (If it helps I homemade the icing)Thanks in Advance! :)Haley
Condensation is normalGas has a small amount of H2 in it, and when burned it reacts with some of the O2 in the air, so one of the biproducts of combustion is steamNow the high efficiency furnaces are designed to capture this latent heat in the steam by condensing it into a liquidSo the water is perfectly normalNow to solve your problemI believe you need to locate to trap inside the furnace and clean it outLooking inside the furnaceif you follow the main drain that leads out of the unit, not to confuse you butBut follow that main drain back into the furnace and eventually it will attach the drain trap, also attached to the trap will be some other drain tubing that leads either to the exhaust motor or to the flue pipe inside the furnace, and maybe another that ties to the gas valvei can't say for sure, my company doesn't install Lennox so I don't run into many of the newer onesGood luck
with propane, this would be even more necessary than with natural gasI suspect that you had condensate water freeze in your condensate drain, and it has backflowed to come out of the furnaceif you go up and look at the furnace you should see a white drain pipe coming out of the furnace and going outside, somewhereif you check the outside part, you'll probably find it is clogged with iceheating it up with a hairdryer should thaw it out and let it drain properlyassuming that is the correct solution, see if the heating guys will rearrange it so it doesn't have the freezing issuemop up the water with rags, or sponges, to minimise the damage to your sheetrock, and check to make sure it dries the rest of the way outif it shows signs of mildewing, clean it with a bleach solution.
high efficiency plus 90 furnaces produce condensate when furnace is runningTheir should be a 3/4 pvc pipe that drains that condensate from the furnace to either a washer box drain in the house or to the exteriorThis line could be plugged or frozenThese furnaces produce gallons of condensate daily in cold weather so you need to get to the bottom of this prontoGet your furnace installation manual that the installer should have left and look up condensate disposal in the manual so you'll know what you're looking for then check it out to find out why condensate is backing up into the trunk line instead of draining outYou'll want to find out why the secondary condensate drain failed as well.
Well I don't no the answer to your question, sorryBut, I think it would be a good idea to rap some towels around everything, maybe a tarp under if possible, check on it every hour or so, change towels and such if they get to wetJust try to hang in there till you can get someone out there to look at itHope I helped in some way.
Chemical reaction 1: Your cupcake mix probably contains sodium bicarbonate (baking soda)In water, the sodium bicarbonate decomposes to form carbonic acid (a mild acid) and OH- ions (if you don't know what those ions are, don't worry)This sets the stage forChemical reaction 2: The carbonic acid is unstable, and breaks down into carbon dioxide and waterThe carbon dioxide bubbles make your cupcake batter riseThis happens faster when you add an acid to the batterYour cupcake batter probably has an acid salt in it, like cream of tartar or sodium aluminum sulfate(Baking soda pre-mixed with the perfect amount of cream of tartar and sodium aluminum sulfate is packaged and sold as baking powder.) Chemical reaction 3: When you bake the cupcakes, the surface brownsThe browning is called the Maillard reaction(Maillard is pronounced like the words my yard.) The Maillard reaction happens when amino acids (the building blocks of proteins) and sugars are heated togetherThe amino acids and sugars combine to make hundreds of chemical compounds, which make hundreds of flavorful chemicalsIt also turns cooked food brown (Note: The Maillard reaction is different from caramelization, another way that cooked foods brownIn the Maillard reaction, sugars react with amino acids; when caramelization happens, the sugars themselves break down and recombine.) Chemical reaction 4: Sometimes you burn the cupcakes, right? That's another chemical reaction, combustionAt higher heat, those starches and other chemicals in your cupcake will react with oxygen, producing carbon dioxide and oxidesThose oxides are the blackened bits on your cupcakes.
