<h2>Answer:</h2>

Mass = 0.1667 g

<h3>Explanation:</h3>

Given data:

Density of cube =  10 g/cm3

Volume of cube  = 3 cm x 2 cm x 10 cm = 60 cm3

Mass of cube = ?

Solution:

Mass = Density/Volume

By putting values in above formula:

Mass = 10/60 = 0.1667 g

<u><em>Hence the mass of a cube is the density/volume of the cube. As the density of the cube is very less than volume, so its mass is also less than 1 which is 0.1667 g. </em></u>

d=m/V so m=Vd

m=60cm^3 * 10g/cm^3=600g

What is the formula of the compound formed between chlorine and calcium?
VLD [36.1K]

the formula  of the compound that  is formed  between  chlorine and calcium  is CaCl2


explanation

chlorine (non  metal)  react  with Calcium ( a metal)  to  form an ionic compound  CaCl2

Ionic compound   is formed when metal  loses electrons to form cation ( a  positively charged ion)  while  non metal  gains electrons  to  form anion (  a  negatively  charged ion)

An ionic compound is formed when calcium   metal(Ca) loses two electron to form   Ca2+ cation ,  while   2 chlorine atom  gain  one electron each to form cl- anions.


  • when writing  down  the formula  of ionic compound  cation  symbol  is written first  followed by  anion symbol.

Therefore the formula  of ionic compound formed between chlorine  and calcium is CaCl2

Why does table salt dissolve more rapidly than rock salt
Sergio [31]
Because in rock salt, the molecules are packed together and they take longer time to separate and dissolve. As for table salt the molecules are less packed together and take less time to dissolve. Think it like this. The more packed or tightly the substance/object is, the longer it will take for the object to dissolve. The less packed the object/substance is the faster it takes to dissolve. Hope this helped :)

An inhibitor is added to an enzyme-catalyzed reaction at a concentration of 26.7 μM. The Vmax remains constant at 50.0 μM/s, but
fomenos

Using the Michaelis-Menten equation competitive inhibition, the Inhibition constant, Ki of the inhibitor is 53.4 μM.

<h3>What is the Ki for the inhibitor?</h3>

The Ki of an inhibitor is known as the inhibition constant.

The inhibition is a competitive inhibition as the Vmax is unchanged but Km changes.

Using the Michaelis-Menten equation for inhibition:

  • Kma = Km/(1 + [I]/Ki)

Making Ki subject of the formula:

  • Ki = [I]/{(Kma/Km) - 1}

where:

  • Kma is the apparent Km due to inhibitor
  • Km is the Km of the enzyme-catalyzed reaction
  • [I] is the concentration of the inhibitor

Solving for Ki:

where

[I] = 26.7 μM

Km = 1.0

Kma = (150% × 1 ) + 1 = 2.5

Ki = 26.7 μM/{(2.5/1) - 1)

Ki = 53.4 μM

Therefore, the Inhibition constant, Ki of the inhibitor is 53.4 μM.
