Soil acidification is a circumstance which will most likely lead to a change in the nutrient cycling that will have a detrimental impact on plant growth.

<h3>What is the main use of nitrogen?</h3>

The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. N must first be combined with hydrogen to create ammonia in order to create these products. The Haber process is used for this. Similar to chlorine gas and carbon monoxide poisoning, nitrous oxide poisoning is detrimental to all living things.

<h3>Why is nitrogen poisonous?</h3>

Effects on health. The majority of greater nitrogen oxides are irritants to the eyes, skin, and respiratory system. Except at deadly quantities, where arginine may kill more quickly, no2 is a corrosive chemical that, when in contact with water, produces nitric and nitrous acids.

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

Reaction equation is given as;

C + O₂ → CO₂

In this reaction, C and O₂ are the reactants

CO₂ is the product of the reaction.

This reaction is called a combination reaction in which two species combines to give a product.

Sodium hydroxide reacts with aluminum and water to produce hydrogen gas:2 Al(s) + 2 NaOH(aq) + 6 H2O(l) → 2 NaAl(OH)4(aq) + 3 H2

Kay [80]

Answer: 0.147 grams

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Al=\frac{1.33g}{27g/mol}=0.049moles$

$\text{Moles of} NaOH=\frac{4.25g}{40g/mol}=0.106moles$

$2Al(s)+2NaOH(aq)+6H_2O(l)\rightarrow Na(Al(OH)_4(aq)+3H_2(g)$

According to stoichiometry :

2 moles of $Al$ require = 2 moles of $NaOH/tex]Thus 0.049 moles of [tex]Al$ will require= $\frac{2}{2}\times 0.049=0.049moles$ of $NaOH$

Thus $Al$ is the limiting reagent as it limits the formation of product and $NaOH$ is the excess reagent.

As 2 moles of $Al$ give = 3 moles of $H_2$

Thus 0.049 moles of $Al$ give = $\frac{3}{2}\times 0.049=0.0735moles$ of $H_2$

Mass of $H_2=moles\times {\text {Molar mass}}=0.0735moles\times 2g/mol=0.147g$

Thus 0.147 g of $H_2$ will be produced from the given masses of both reactants.
