Answer: [tex]N_2(g)+3H_2(g)\rightarrow 2NH_3(g)[/tex]
Explanation: According to the law of conservation of mass, mass can neither be created nor be destroyed. Mass remains conserved. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Haber's process used for manufacturing of ammonia in terms of balanced chemical equation is:
[tex]N_2(g)+3H_2(g)\rightarrow 2NH_3(g)[/tex]
The balanced chemical equation for the synthesis of ammonia using the Haber-Bosch process is N₂(g) + 3H₂(g) → 2NH₃(g), which is a crucial industrial reaction for producing fertilizers.
Explanation:The balanced chemical equation for the Haber-Bosch process, where nitrogen and hydrogen combine to form ammonia, is as follows:
N₂(g) + 3H₂(g) → 2NH₃(g)
This represents the direct combination of nitrogen gas (N₂) and hydrogen gas (H₂) to yield ammonia (NH₃), which is widely utilized in the production of fertilizers. The Haber-Bosch process operates under high pressure and temperature to favor the formation of ammonia from its constituent elements. The coefficients in the balanced equation indicate the molar ratio at which the reactants combine to form the product.

Write a net ionic equation to show why solid lithium hydroxide, lioh (s), forms a basic solution when it dissolves in water.
The net ionic equation for the dissolution of lithium hydroxide (LiOH) in water is LiOH(s) -> Li+(aq) + OH-(aq). The hydroxide ions (OH-) created from this process make the solution basic as they can accept H+ ions. Being an alkali metal, lithium forms a strong base when it reacts with water due to the complete dissociation of its hydroxide ions.
Explanation:The topic at hand is the dissolution of solid lithium hydroxide, LiOH (s), in water to form a basic solution. This process can be understood through the concept of the alkali metals reacting with water to form hydrogen gas and a basic solution of the metal hydroxide.
The net ionic equation for this process is:
LiOH(s) -> Li+(aq) + OH-(aq)
When lithium hydroxide (LiOH) dissolves in water, it dissociates into lithium ions (Li+) and hydroxide ions (OH-). It's the OH- ions that make the solution basic, as they can accept H+ ions.
In general, alkali metals like lithium form strong bases when they react with water due to the complete dissociation of their hydroxide ions in the solution. The formation of these hydroxide ions is what characterizes the solution as basic.

When water and toluene are mixed two layers form. is the bottom layer water or toluene?
Final answer:
In a mixture of water and toluene, the bottom layer is water due to its higher density compared to the less dense toluene, which forms the top layer.
Explanation:
When water and toluene are mixed, two layers form due to their differences in polarity and density. Water is a polar molecule while toluene is nonpolar. Given the difference in densities, with water being more dense, the bottom layer will be water, and the top layer will be toluene. In a practical setting, this can be observed in a separatory funnel where the denser layer settles at the bottom.
Experiments often utilize this property of immiscibility, where the addition of water to a mixture can help in identifying the aqueous layer by its increase in volume. When toluene and water are mixed, the toluene would form the upper layer because it is less dense than water, in the same way oil forms a top layer when mixed with water.
Water and toluene are immiscible liquids, which means they do not mix together and form separate layers. In this case, water, being more dense than toluene, settles at the bottom. This can be observed when water droplets fall through the top layer to mix with the bottom layer.
Additionally, the higher mole fraction of toluene in the bottom layer also indicates that it is the toluene layer. Toluene and water form separate layers because toluene is less dense and immiscible in water.

What is the limiting reactant when 4.5 moles of aluminum react with 6.7 moles of oxygen gas? (4 points) Unbalanced equation: Al + O2 → Al2O3
Answer: -
The limiting reactant is Al.
Explanation: -
Number of moles of O₂ = 6.7 moles
The balanced chemical equation for this process is
4 Al + 3 O₂ → 2Al₂O₃
From the balanced reaction we see
3 mol of O₂ would react with 4 mol of Al
6.7 mol of O₂ would react with [tex] \frac{4 mol Al x 6.7 mol O2}{3 mol O2} [/tex]
= 8.933 mol of Al
But the number of moles of Al present is only 4.5 mol.
Hence the limiting reagent is Al.

Describe how the burning of fossil fuels affects the carbon cycle
The burning of fossil fuels raises CO₂ levels in the atmosphere, intensifying the greenhouse effect and causing global climate change. Deforestation further aggravates this issue as there are fewer trees to absorb CO₂.
Explanation:Impact of Fossil Fuel Combustion on the Carbon Cycle
The burning of fossil fuels has significantly altered the natural carbon cycle. During this cycle, plants remove carbon dioxide (CO₂) from the atmosphere through photosynthesis, and animals and plants return CO₂ through respiration. The extraction and combustion of fossil fuels—coal, oil, and natural gas—release large amounts of CO₂ that have been stored underground for millions of years. This excess CO₂ contributes to a rise in atmospheric CO₂ levels beyond what is used by photosynthesis, leading to an enhanced greenhouse effect. Greenhouse gases trap solar energy in the form of heat, akin to the panes of a greenhouse, which has resulted in global climate change. Deforestation exacerbates this issue by decreasing the number of trees that can absorb CO₂. Additionally, increased atmospheric CO₂ has led to ocean acidification, affecting marine life adapted to a narrow pH range.
The greenhouse effect and the increase in global temperatures, known as global warming, have several negative effects. This includes the rise of sea levels that threaten coastal cities, more extreme weather events, and disruption of ecosystems. It is thus important to shift from fossil fuels to non-carbon energy sources like hydro, solar, wind, and nuclear to mitigate these impacts.

Which pair of atoms has the highest electronegative difference
The highest electronegativity difference is between (d) O-H.
The pair of atoms with the highest electronegativity difference is O - H, with a difference of 1.4. This indicates a polar covalent bond. Electronegativity measures how strongly an atom attracts electrons in a bond.
The question asks which pair of atoms has the highest electronegativity difference. Electronegativity is a measure of how strongly an atom can attract electrons in a bond. Here, we compare the electronegativity differences of several atom pairs:
H - S: The electronegativities are H (2.1) and S (2.5) with a difference of 0.4.
H - Cl: The electronegativities are H (2.1) and Cl (3.0) with a difference of 0.9.
N - H: The electronegativities are N (3.0) and H (2.1) with a difference of 0.9.
O - H: The electronegativities are O (3.5) and H (2.1) with a difference of 1.4.
C - H: The electronegativities are C (2.5) and H (2.1) with a difference of 0.4.
Thus, the pair with the highest electronegativity difference is O - H, with a difference of 1.4. This significant difference indicates a polar covalent bond between oxygen and hydrogen.

Metamorphic rocks are formed due to physical and chemical change by heat and pressure of existing rocks. The magma heat warms the enclosing rocks making them change.
The rocks buried underground in the Earth, when they are subjected to heat and pressure these rocks change into metamorphic rocks.The pressure crushes the rock to produce metamorphic rock.
Suggest a way to determine whether a colorless liquid is pure water or a salt solution
Explanation:
It is known that the boiling point of pure water is [tex]100^{o}C[/tex]. But when an impurity or a solute has been added into the water then there occurs an elevation in the boiling point of water.
As a result, addition of a solute into the water will lead to an increase in the boiling point of water.
For example, if common salt (NaCl) is added into water then it will completely dissolve in water leading to the formation of a cleat solution. But when we boil this solution then its boiling point will be greater than [tex]100^{o}C[/tex].
This will prove that it is a salt solution and not a colorless liquid.
Thus, we can conclude that by boiling the given colorless liquid we can determine whether it is a pure water or a salt solution.
To determine if a colorless liquid is pure water or a salt solution, you can perform a conductivity test.
Explanation:A way to determine whether a colorless liquid is pure water or a salt solution is by performing a conductivity test. Pure water has very low conductivity, while a salt solution will have higher conductivity due to the presence of ions. To conduct the test, you can use a conductivity meter or a simple circuit with a bulb and two electrodes.
Start by connecting the circuit and immersing the electrodes into the liquid. If the bulb lights up brightly, it indicates that the liquid is a salt solution. If the bulb remains dim or does not light up at all, it suggests that the liquid is pure water.
