b) 7.25 mol
Explanation:
Please see the attached picture for the full solution.
Question 17:
False; cutting hair would change what it looks like but, braiding it keeps it the same substance it is.
Question 18 :
My best guess would either be A or D. I would lean more towards D because if there are different mixtures then it depends on what you are mixing.
Hope it helps in some way. <3
Answer:
Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable
Answer:
248.4 mL
Explanation:
Erlenmeyer = 78.649 g
Erlenmeyer + Water = 327.039 g
Water = (Erlenmeyer + Water) - Erlenmeyer
Water = 327.039 - 78.649
Water = 248.4 g
if the density of water is 1 g/mL, we can say that each mL of water weigh 1 g, so we have 248.4 mL of water in the Erlenmeyer Flask.
Rubisco is an important enzyme that helps in making lifeless carbon of carbon dioxide into organic molecules. Rubisco takes carbon dioxide and attaches it to ribulose bisphosphate, a
short sugar chain with five carbon atoms that has rubp as its shortcut. Rubisco then clips the
lengthened chain into to polyglycerate pices, which are pretty flexible molecules and are also used in the feeding of the plant. Most of it is used in the photosynthesis pathway, but some of it is used to make sucrose
(table sugar) to feed the rest of the plant, or stored away in the form
of starch for later use. Hence, rubisco is crucial in the storing of the energy that is created from photosynthesis.
