Explanation:

A mixture in which solute particles are unevenly distributed into the solvent is known as a heterogeneous mixture.

For example, oil present in vinegar will unevenly mix together.

Whereas a mixture in which solute particles are evenly distributed into the solvent is known as a homogeneous mixture.

For example, salt dissolved in water is a homogeneous mixture.

Therefore, when a salad dressing is made by a chef  by mixing oil, vinegar, and spices then it is a heterogenous mixture.

In the molecular orbital model of cyclobutadiene, how many -antibonding molecular orbitals are there?
Citrus2011 [14]

There are one antibonding molecular orbitals present in molecular orbital model of c.

The cyclobutadiene has a pi system comprised of four  individual atomic p - orbital and thus should have a four pi   molecular orbitals. The compound is the prototypical antiaromatic hydrocarbon with 4 \pi - electrons .  Its rectangular structure is the result of jahn teller reaction which disorder the molecule and lowers its symmetry , converting the triplet to a singlet ground state. It is a small annulene . The  delocalisation energy of the  \pi   electrons of the cyclobutene is predicted to be zero .

Write the simple equation that describes the action of the enzyme catalase.
Nataly [62]

Here we have to write a simple equation which describes the action of the enzyme catalase.

The equation is: The concentration of the complex [ES] = \frac{[E]0}{1+\frac{Km}{[S]} }

Let us consider an enzyme catalyses reaction E + S ⇄ ES → E + P

Where E, S, ES and P are enzyme, substrate, complex and product respectively.

The concentration of the complex [ES] = \frac{[E]0}{1+\frac{Km}{[S]} }, where K_{m} is the Michaelis constant.

[E]₀ and [S] is the initial concentration of enzyme and concentration of substrate respectively.

What volume of a 3.0 M stock solution of H2SO4 is needed to prepare 2.8 L of a 1.6 M H2SO4 solution?
Georgia [21]
Use M1V1 = M2V2 to solve
3(V1) = 2.8 * 1.6
3(V1) = 4.48
V1 = 1.493 L of stock solution
