Answer: D
Explanation:
because mold is a chemical reaction with with the air that's why the put a date cause the bread can only last for so long in till the chemical reaction.But D is is right because your body has to go though a chemical reaction in or to digest it and and break it down even more.So D would be the right answer cause that's where most of your chemical reaction happens when food is swallowed into the stoamch i hope i was able to explain it as much as i can
Answer:
0.68 V
Explanation:
For anode;
3Mg(s) ---->3Mg^2+(aq) + 6e
For cathode;
2Al^3+(aq) + 6e -----> 2Al(s)
Overall balanced reaction equation;
3Mg(s) + 2Al^3+(aq) ----> 3Mg^2+(aq) + 2Al(s)
Since
E°anode = -2.356 V
E°cathode = -1.676 V
E°cell=-1.676 -(-2.356)
E°cell= 0.68 V

Non-volatile mixtures can be separated using a process called thin layer chromatography (TLC). Since acetaminophen has a hydroxyl group, it is more polar than phenacetin.
<h3>Does acetaminophen or phenacetin have a lower Rf value?</h3>
Since acetaminophen has a hydroxyl group, it is more polar than phenacetin. Phenacetin will be more soluble and migrate to the top than the polar component because we are employing a non-polar solvent.
Non-volatile mixtures can be separated using a process called thin layer chromatography. The experiment is carried out on a piece of glass, plastic, or aluminum foil that has been lightly covered with an adsorbent substance. Typically, silica gel, cellulose, or aluminum oxide are utilized as the substance.
Because acetaminophen is more polar than phenacetin and nonpolar molecules pass through silica gel more quickly than polar ones do, acetaminophen would have a lower Rf value.
