C can be the only correct answer - 6.023 x 10^23 is the amount of molecules in a mol of an element. 4.5 x 6.023 x 10^23 can not equal anything but C.
4.5 x 6.023 x 10^23 = 2.71035 x 10^24
Answer:
When an apple is cut or bruised the oxygen goes into the injured plant tissue. It begins to oxidize from the reaction of the enzymes and oxygen. The apple produces melanin to protect it causing it to brown. Using vinegar and lemon juice help stop the browning because lemon juice has a compound that reacts with oxygen before the oxygen can react with apple. Also, vinegar and lemons are very acidic which slows the browning reaction.

Answer:
6AgI +Fe2(CO3)3 = 2FeI3 + 3Ag2CO3
Explanation:
Balance the equation to find the answer. The easiest place to start is with the C’s and H’s since they only appear once on both sides of the equation:
C4H8 + 6O2 —> 4CO2 + 4H2O
The O2 has already been balanced for us (but normally you would add the number of O’s on the right after balancing C’s and H’s and use that to balance the O’s on the left).
As you can see you get 4 molecules of CO2 and 4 of H2O.
