Answer:
The number of moles of solute present in 4.00 L of an 8.30 M solution is 33.2
Explanation:
The Molarity (M) or Molar Concentration is the number of moles of solute per liter of solution; in other words it is the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units (
) or M.
In this case:
- molarity= 8.30 M
- number of moles of solute= ?
- volume= 4.00 L
Replacing:
Solving:
number of moles of solute= 8.30 M* 4 L= 8.30 * 4 L
number of moles of solute =33.2
<u><em>The number of moles of solute present in 4.00 L of an 8.30 M solution is 33.2</em></u>
Answer:
D. C14 appears at C‑6 of fructose 6‑phosphate
Explanation:
Conversion of glucose B-phosphate via 6-phospho-
gluconate to pentose phosphate and CO2 followed by conversion
of the pentose phosphate to fructose 6-phosphate and glyceralde-hyde phosphate followed by conversion of the fructose 6-phos-
phate to glucose g-phosphate .
Answer:
A. When water moves into a crack and freezes, it expands and forces the crack wider.
Explanation:
A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making the crack larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the crack. Once the water freezes again when the temperature drops, the expansion of the ice causes further expansion to the crack.
