Graphite is a polymorph of the element carbon.
Answer:
the atom
Explanation:
The bread and cheese separately represent the atom because both bread and cheese are different from one another and we cannot assume it as a molecule because molecules formed when the group of atoms combine together by making bonds with each other and we know that bread and cheese did not make bonds with each other, they only attached, so we called them atoms not molecule.
Hey! Let me help you!
C)
<span>What
additional volume of 10.0 M HCl would be needed to exhaust the
remaining capacity of the buffer after the reaction described in Part B?
In other words, how much more of this HCl solution is required to
consume the remaining Tris in the buffer?
let x = how much more solution needed
x = 1.8 mL <=========
Your answer is 1.8 mL as it is needed for more of this HCI solution is requires to consume the remaining Tris in the buffer!
Have an awesome day! :D

Answer:
Explanation:
Hello!
In this case, since the formation of ammonia by starting with nitrogen and therefore hydrogen is:
Which has an energy of reaction of:
We can compute the energy required for this reaction by first computing the moles of ammonia yielded by 21.7 grams of nitrogen (28.02 g/mol) via stoichiometry:
Thus, the energy turns out:
