Planes stay in the air by a force called lift which is gained as a plane rises in the air as air goes under the plane a force called lift is applied because hot air rises so the hot air also pushes the plane goes up.
hope this helps :3

10.3 is good the correct rounding of three sig figures
Answer:
10.85 g of water
Explanation:
First we write the balanced chemical equation
Then we calculate the number of moles of nitric acid produced
n(HNO3) = 
According to the balanced equation, water needed in moles is always half the number of moles of HNO3 produced. So since we will produce 1.2044 mol of HNO3, we will need 0.6022 mol of water. Now to calculate what mass that is:
mass(water)=number of moles*molar mass=0.6022mol*18.02g/mol=10.85g
Answer: it started too rot over time mold over time and decay and if you cooked a apple it would melt like ice cream cause of the heat waves and if the apple is surrounded by air i think what would happen it would still rot I guess but i wouldnt know for sure cause things with air take time too rot and things with air rot faster and slicing the apple into more pieces would make it decay or rot or mold faster cause its open and accepting everything it sees like bacteria bugs all that
Explanation: like the longer a apple is left half open it starts too rot then mold over time getting all bad and not good too eat or decay
read it all the stuff is in there i think
