How many moles are in 5.6x1025 molecules of calcium oxide?
Vlad1618 [11]

Answer:

<h2>93.02 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{5.6 \times  {10}^{25} }{6.02  \times  {10}^{23} }  \\  = 93.023...

We have the final answer as

<h3>93.02 moles</h3>

Hope this helps you

Identify the four parts of the potential energy diagram
Leni [432]

Answer:

Reactants, Activation energy, Energy released by the reaction and Products

Explanation:

This energy profile is that of an exothermic reaction. In an exothermic reaction, heat is liberated to the surrounding. The surrounding becomes hotter than the environment.

The first box to the left is the reactants which signifies the species combining together.

The topmost box is the activation energy which is the energy barrier that must be over come before a reaction takes place.

The box underneath is the energy change. Here, energy is being released.

The right most box is the product of the reaction.

A newly discovered unicellular organism from acidic mine drainage is found to contain a cell wall, a plasma membrane, two flagel
makvit [3.9K]

Answer:

<em>The correct option is D)  a motile eukaryote</em>

Explanation:

Peroxisomes are structures which are present only in the plant or animal cells. Hence, based on this observation we can easily tell that the organism which is newly discovered is a eukaryote. Both plants and animals are eukaryotes.

Flagella are structures which are thin and hair shaped. Flagella allow movement of a cell, mostly they allow a whip-like movement. Based on this observation we will conclude that the organism discovered is a motile eukaryote.
