Explanation:
Graphite and diamond are allotropes of carbon. Allotrophy is the existence of an element in more than one form but the same physical state. Carbon is an example of element that exhibits allotrophy; these are diamond and graphite; which differ in structure and chemical properties. Another element that exhibits allotrophy is sulfur; with monoclinic and rhombic sulfur.
Explanation:
Because molarity is classified as moles of solute per liter of water, dilution of the water may result in a reduction of its concentration.
Therefore, because the amount of moles of solute has to be constant for dilution, you will use the molarity and volume of that same target solution to calculate how many moles of solute will be present in the sample of the stock solution that you dilute.
c =
⇒ n
=
c
⋅ V
= 0.250 M ⋅ 6.00 L =
1.5 moles HCl
Now all you have to do is figure out what volume of 6.0 M stock solution will contain 1.5 moles of hydrochloric acid
c =
V =
= =
0.25 L
Expressed in milliliters, the answer will be
→ rounded to two sig figs
Answer: Planet A: 76% Nitrogen, 23% Oxygen, 1% Other
Explanation: Hope this helps!
Acidity is caused by a losing <span>H+</span><span> ions. How acidic a substance is depends on how easily it will split with the hydrogen ions in water.
In your question, carboxylic acids are the most acidic because they have two oxygen atoms on the carbon to which the carboxyl group is attached, whereas the alcohol only has one and the alkyne has none, like I said earlier, this makes the hydrogen ion partially positive and therefore easier to lose.
