There are several aromatic compounds with the formula c8h9cl. Draw those that have a monosubstituted ring.
anygoal [31]

Answer:

As shown in the attachment.

Explanation:

In this case, there are two isomers possible. Isomers are compounds that have the same molecular formular but different structural formular.

Considering the hydrocarbon C8H10, which has 8C expected saturated hydrocarbon. however when there is an excess of 8H, we have C8H18 which is the formular of octane, a member of the alkane family and from monosubstitution reaction which involves reaction with halogens (particularly Chlorine), the reaction will be a repeated substitution reaction where chlorine will be replaced with each of the hydrogen.

cestrela7 [59]

Answer:  equal to the substrate concentration when the reaction rate is half its maximal value.

Explanation: the KM is known as The Michaelis constant. The value of the Michaelis constant KM is numerically equal to the substrate concentration at which the reaction rate is half of Vmax.

The KM value for an enzyme depends on the particular substrate and on environmental conditions such as pH, temperature, and ionic strength.

1.) C6H12O6 (aq) is a(an)?
Marina86 [1]

Answer:

1) D. Dissolved Molecule

2) C. 11.30 M

Explanation:

<u><em>Q1:</em></u>

  • Glucose (C₆H₁₂O₆) is a non-polar molecule.
  • When it is dissolved in water, it will be a dissolved molecule.
  • It can not be ionized in water.
  • So, the right choice is: <em>D. Dissolved molecule.</em>

<u><em>Q2</em></u>:

  • The molarity is the no. of moles of dissolved solute in a 1.0 L of the solution.

<em>M = (n)solute (1000/V (mL) of the solution)</em>

n of LiCl = 2.60 mol, V = 230.0 mL.

∴ M = (n)solute (1000/V (mL) of the solution) = (2.60 mol)(1000)/(230.0 mL) = 11.30 M.
