Consider the following three-step reaction pathway.

Alenkinab [10]

Answer:

$NO \longrightarrow N_2O_2 \longrightarrow N_2O \longrightarrow N2$

Explanation:

The intermediates are the products of all the steps of the reaction pathway, with the exception of the last one. So the intermediates will be:

N2O2 from the first step
N2O from the second step

The list from reactant to final product:

$NO \longrightarrow N_2O_2 \longrightarrow N_2O \longrightarrow N2$

<em>Note: the water is considered a by-product, given that is not the product of interest in this steps.</em>

8. Calculate the number of moles of eachsubstance.a. 5.45 x 1026 particles of methane, CH4

Klio2033 [76]

<em>ANSWER</em>

The number of moles of methane is 905.32 moles

STEP-BY-STEP EXPLANATION:

Given information

The number of particles of methane = 5.45 x 10^26 particles

Let x represents the number of moles of methane

To calculate the number of moles, we will be using the below formula

$\text{Number of particles = number of moles x Avogadro's constant}$

Recall that, the Avogadro's constant is given as

$6.02\cdot10^{23}$ $\begin{gathered} 5.45\cdot10^{26}\text{ = x }\cdot\text{ 6.02 }\cdot10^{23} \\ \text{Divide both sides by 6.02 }\cdot10^{23} \\ x\text{ = }\frac{5.45\cdot10^{26}}{6.02\cdot10^{23}} \\ x\text{ = }\frac{5.45}{6.02}\cdot10^{26\text{ - 23}} \\ x\text{ = 0.9053 }\cdot10^3 \\ x\text{ = 905.32 moles} \end{gathered}$

Therefore, the number of moles of methane is 905.32 moles

What is the best reason for the difference in properties of LiCL and C6H14O

statuscvo [17]

The substances have different atomic masses, one is organic and one is inorganic, and Cl and Oxygen belong to different groups. There are more differences but these are the most basic ones.
