Match each of the following terms from the Michaelis-Menten equation to its correct definition.

Chemistry

Nadya [2.5K]3 years ago
5 0

Answer:

d. 1:B; 2:D; 3:C; 4:A

Explanation:

The Michaelis-Menten equation is:

V_{0}=V_{max}\frac{[substrate]}{[substrate]+K_{m}}

Also

V_{0}=K_{cat}E_{0}\frac{[substrate]}{[substrate]+K_{m}}

Where

Kcat = turn over number [ number of substrate molecules turned over by enzyme]

Vmax = Maximum rate (rate of a reaction when enzyme is saturated with substrate)

Km = is the substrate concentration when the V is numerically equal to half of Vmax

Kcat / Km = Enzyme efficiency.

An aqueous solution contains 0.23 M potassium hypochlorite.
Arturiano [62]

Answer:

0.22 mol HClO, 0.11mol HBr.

0.25mol NH₄Cl, 0.12 mol HCl

Explanation:

A buffer is defined as a mixture in solution between weak acid and its conjugate base or vice versa.

Potassium hypochlorite (KClO) could be seen as conjugate base of HClO (Weak acid). That means the addition of <em>0.22 mol HClO  </em>will convert the solution in a buffer. HBr reacts with KClO producing HClO, thus, <em>0.11mol HBr</em> will, also, convert the solution in a buffer. 0.23 mol HBr will react completely with KClO and in the solution you will have only HClO, no a buffering system.

Ammonia (NH₃) is a weak base and its conjugate base is NH₄⁺. That means the addition of <em>0.25mol NH₄Cl</em> will convert the solution in a buffer. Also, NH₃ reacts with HCl producing NH₄⁺. Thus, addition of<em> 0.12 mol HCl</em>  will produce NH₄⁺. 0.25mol HCl consume all NH₃.

The arrows in the chart below represent phase transitions. Three bars are shown labeled Solid, Liquid, and Gas. They are connect
tester [92]

Answer:

1,2,3

Explanation:

Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.

Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.

Also, transition from solid to liquid requires energy to break intermolecular bonds.

Finally, sublimation requires input of energy in the form of heat.
