which scenario will most likely result in a change to the nitrogen cycle that negatively affects plant growth?

1 answer:

4 0

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.

How many atoms of hydrogen are in two moles of ch4?

ziro4ka [17]

There are four Hydrogen atoms in one molecule of Methane (CH₄).
And there are 6.022×10²³ molecules in 1 mole of CH₄.
So,
Number of Hydrogen atoms is 1 mole of CH₄ are,

= 6.022 × 10²³ × 4

= 2.4 ×10²⁴ Hydrogen Atoms

Now calculating for 2 moles,

As,
1 mole of CH₄ contains = 2.4 ×10²⁴ Hydrogen Atom
Then,
2 moles of CH₄ will contain = X Hydrogen Atoms

Solving for X,
X = (2 moles × 2.4 ×10²⁴ Hydrogen Atom) ÷ 1 mole

X = 4.8 × 10²⁴ Hydrogen Atoms

If 251 mL of 6.0 M H2SO4 is diluted to 500. mL, what is its new molarity?

kolezko [41]

Answer:

<u>3.0M</u>

Explanation:

The dilution formula is:

$M_1\times V_1=M_2\times V_2$

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.

Substitute:

M₁ = <em>6.0M</em>

M₂ = unknown

V₁ = <em>251 mL</em>

V₂ = <em>500. mL</em>

$6.0M\times 251ml=M_2\times 500.ml$

Clear M₂ and compute:

$M_2=6.0M\times 251ml/500.ml\approx3.0M$

Which of the following gases would have the greatest kinetic energy at 300 K?

tekilochka [14]

Answer:

D. All of them would have the same kinetic energy

Explanation:

The expression for the kinetic energy of the gas is:-

$K.E.=\frac{3}{2}\times K\times T$

k is Boltzmann's constant = $1.38\times 10^{-23}\ J/K$

T is the temperature

<u>Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are $N_2,\ NH_3\ and\ Ar$ will posses same value of kinetic energy.</u>
