Answer:
D. protons that is the answer
The action produces heat energy.
Answer:
Of lower concentration or less concentrated
Explanation:
Osmosis is the movement of solvent from a region of lower concentration of solute to a region of higher concentration of solute through a semipermeable membrane in order to equalize the concentration of the solutions on both sides.
Since the membrane of the bag is semipermeable, then the fact that the bag in the beaker decreased in size, lost volume, and became flaccid indicates that the solution in the bag is of lower solute concentration than the solution in the beaker hence the movement of water molecules into the beaker by osmosis.
Answer:
2-ethoxy-2-methylpropan-1-ol
Explanation:
On this reaction, we have an "<u>epoxide"</u> (2-methyl-1,2-epoxypropane). Additionally, we have <u>acid medium</u> (due to the sulfuric acid ). The acid medium will produce the <u>hydronium ion</u> (). This ion would be attacked by the oxygen of the epoxide. Then a <u>carbocation</u> would be produced, in this case, the most stable carbocation is the <u>tertiary one</u>. Then an <u>ethanol</u> molecule acts as a nucleophile and will attack the carbocation. Finally, a <u>deprotonation </u>step takes place to produce <u>2-ethoxy-2-methylpropan-1-ol</u>.
See figure 1

The new pH of the solution after the addition of water would be 13.22.
<h3>
Total volume of the solution</h3>
V(total) = 609 ml + 594 ml
V(total) = 1203 ml
<h3>Concentration of water </h3>
C = (594 ml)/(1203 ml)
C = 0.493
pOH = -log(0.493)
pOH = 0.31
New pH of the solution = 13.5292 - 0.31 = 13.22
