Answer:

the nature of reactants is different from the other factors that affect rates because it explains the difference in rates of two different reactions but cannot be used to make one reaction faster or slower...

in both cases, a single displacement reaction occurs between a mental and water .

Consider the following reaction: 2 NO(g) + 5 H2(g) → 2 NH3(g) + 2 H2O(g) Which set of solution maps would be needed to calculate

Leto [7]

Answer : The correct option is, (I) $gNO\rightarrow molNO\rightarrow molNH_3\rightarrow gNH_3$

Solution : Given,

Mass of NO = 45.8 g

Mass of $H_2$ = 12.4 g

Molar mass of NO = 30 g/mole

Molar mass of $H_2$ = 2 g/mole

Molar mass of $NH_3$ = 17 g/mole

First we have to calculate the moles of NO and $O_2$ .

$\text{ Moles of }NO=\frac{\text{ Mass of }NO}{\text{ Molar mass of }NO}=\frac{45.8g}{30g/mole}=1.53moles$

$\text{ Moles of }H_2=\frac{\text{ Mass of }H_2}{\text{ Molar mass of }H_2}=\frac{12.4g}{2g/mole}=6.20moles$

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$2NO(g)+5H_2(g)\rightarrow 2NH_3(g)+2H_2O(g)$

From the balanced reaction we conclude that

As, 2 mole of $NO$ react with 5 mole of $H_2$

So, 1.53 moles of $NO$ react with $\frac{1.53}{2}\times 5=3.82$ moles of $H_2$

From this we conclude that, $H_2$ is an excess reagent because the given moles are greater than the required moles and $NO$ is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of $NH_3$

From the reaction, we conclude that

As, 2 mole of $NO$ react to give 2 mole of $NH_3$

So, 1.53 mole of $NO$ react to give 1.53 mole of $NH_3$

Now we have to calculate the mass of $NH_3$

$\text{ Mass of }NH_3=\text{ Moles of }NH_3\times \text{ Molar mass of }NH_3$

$\text{ Mass of }NH_3=(1.53moles)\times (17g/mole)=26.0g$

Therefore, the maximum mass of $NH_3$ produced 26.0 grams.

Lizards are reptiles that are closely related to snakes. Like all reptiles, lizards have scaly skin and are ectotherms—cold-blooded animals whose body temperature varies with the temperature of their surrounding environment. Most lizards are native to the tropics, but a number of species are found in temperate regions.Chameleons, iguanas, skinks, monitors, anoles, and geckos are some of the many different types of lizards.

A number of lizard species have adapted to life in the desert. Some desert lizards have toes fringed with spiny scales to help them run across the sand without sinking. Others burrow into the sand to escape the desert's intense heat, to hide from predators, or to search for small animals that they prey upon. Some burrowing lizards even have clear scales on their eyelids that protect their eyes but still allow them to see while they move under the sand.

I hope you find it helpful!!!!!
