Which of the following enthalpies of reaction would the reaction represented by the diagram have?

1 answer:

8 0

<span>In chemical reactions, the internal energy represents the total energy of the system and is often called Enthalpy. The x-axis represents the reaction progress. Chemical reactions proceed (or are read) from left to right. Therefore, looking at the potential energy diagram, the reactants are usually found to the left on the diagram and the products on the right.</span>

Calculate the number of moles of iodine in 7.68×10^25 molecules of I2

Dmitrij [34]

Answer:

<h2>127.57 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

$n = \frac{7.68 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 127.574750...$

We have the final answer as

<h3>127.57 moles</h3>

Hope this helps you
