Answer:

Which of the following

properties distinguishes a solution

oversaturated with a dilute?

  • The supersaturated solution is one in which the solvent has dissolved more solute than it can dissolve in the saturation equilibrium.  The solute can be a solid, or a gas. The molecules of the solvent surround those of the solute and seek to open space between themselves to be able to harbor more amount of solute.
  • A dilute solution is a solution that has not reached the maximum concentration of solute dissolved in a solvent. The additional solute will dissolve when added in a dilute solution and will not appear in the aqueous phase.   It is considered a state of dynamic equilibrium where the speeds in which the solvent dissolves the solute are greater than the recrystallization rate.

How reactive is an atom of Sodium(Na) and why?
s344n2d4d5 [400]
3rd one:
it is very reactive because it does not have a full Valence shell.

this is because it's in group 1 so it has one electron in its outer shell, and it wants to have a full outer shell ( which it can gain by losing the electron in a reaction).

Hope this helps :)

A student is told to use 20.0 grams of sodium chloride to make an aqueous solution that has a concentration of 10.0 grams of sod
Butoxors [25]

Volume of the solution = 20.0 g NaCl * \frac{1 L solution}{10.0 g NaCl}

= 2 L solution x \frac{1000 mL}{1 L} =2000 mL

Volume of solute = 7.5 mL

Volume of water (solvent) = 2000 mL - 7.5 mL = 1992.5 mL water

If maltose undergoes hydrolysis what subunits does it results to?
Levart [38]
<h3><u>Answer;</u></h3>

Two glucose molecules

<h3><u>Explanation;</u></h3>
  • Maltose is a disaccharide that is made up of two glucose molecules joined with an alpha(1-4) bond.
  • <em><u>Maltose is produced by the enzymatic hydrolysis of starch, a polysaccharide, catalyzed by the enzyme amylase. Maltose is then hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.</u></em>
  • <em><u>The enzyme maltase efficiently catalyses the hydrolysis of maltose into 2 glucose molecules. </u></em>
