When nitrogen gas and hydrogen gas combine, there is the formation of ammonia as a product.
A reaction that produces fire and occurs at a high temperature is referred to as a combustion reaction. An exothermic, redox reaction known as combustion typically takes place between a fuel and primarily oxygen in the environment.
Because this reaction cannot take place in the absence of oxygen, oxygen is the primary reactant in combustion reactions. When a fuel burns through completely, carbon dioxide and heat are produced.
Ammonia was created using the Haber process, which involved the reaction of nitrogen (N2) and hydrogen (H2) to create ammonia (NH3).
N₂ + 3H₂ ⇄ 2NH₃, ΔrH = -92kJ/mol.
Since the enthalpy change for the reaction that produces ammonia is negative, which indicates that energy is released during this process, ammonia formation is also an exothermic process.
Three moles of hydrogen gas and one mole of nitrogen gas combine to make one mole of ammonia.

When fireflies give off light a reaction takes place. Is this an example of endothermic or exothermic reaction?.
Most likely, exothermic processes are what cause the light that fireflies emit. because fuel and oxygen undergo a chemical process that produces carbon dioxide and water.
In thermochemistry, an exothermic process is one "for which the overall standard enthalpy change H is negative." Exothermic processes typically result in heat. A reaction for which the overall standard Gibbs energy change G is negative is what the term "reaction" according to the IUPAC means.
The exergonic response and the phrase are commonly mistaken. A very exothermic reaction will often accompany an exergonic reaction since "H" significantly contributes to "G." The majority of the remarkable chemical reactions presented in classrooms are exothermic and exergonic processes.
On the other hand, an endothermic reaction typically produces heat and is brought on by a rise in the entropy of the system.

what is the concept behind common ion effect and how is this being tested in part i of the experiment? what is the concept behind part ii of the experiment?
The concept behind the common ion effect is ionization.
When another electrolyte (which includes an ion that is also present in the first electrolyte, i.e., a common ion) is added, the common ion effect suppresses the ionization of the first electrolyte. It is thought to follow from Le Chatlier's principle (or the Equilibrium Law).
An increase in the concentration of one of the ions dissociated in the solution by the addition of another species containing the same ion will result in an increase in the degree of association of ions in a solution where there are several species associating with each other via a chemical equilibrium process.
In the compounds of transition metals, this effect cannot be seen. This occurs as a result of the d-block elements' propensity to produce complex ions. The substance cuprous chloride, which is insoluble in water, is a good example of this. When chloride ions are added, the molecule forms the water-soluble CuCl2 complex ion, which can then be dissolved in water.

briefly describe the following modes of reproduction, in terms of: (a) number of parents; (b) genotypes of the offspring q8.1.1 asexual reproduction q8.1.2 sexual reproduction
The modes of reproduction are sexual and asexual reproduction. The number of parent involved in asexual reproduction is one and two in case of sexual reproduction.
Modes of reproduction:-
Sexual reproduction: It is a kind of reproduction when two male and female organisms' gamete cells unite to create a single zygote. This zygote divides its genetic material in half and gives the other half to the mother and father. There are many diverse methods of sexual reproduction in both plants and animals, however the fundamentals are the same. The freshly developed individual created through sexual reproduction is genetically and physically distinct from the parents.
Fertilization is the process through which sperm and egg (ovum) combine to form a zygote, which is how humans reproduce sexually. The critical phase of sexual reproduction is fertilization. Sexual reproduction will not be complete without fertilization.
Sexual reproduction: It is a reproductive method in which a single organism participates. The resultant child has nearly always the same number of chromosomes as the mother and is genetically similar to her. Thus, they are referred to as clones. They are also identical replicas of their parent cell. Different entities choose to reproduce asexually. Budding (e.g., Hydra), binary fission (e.g., Amoeba, bacteria), spore production (e.g., ferns), fragmentation (e.g., Planaria), and vegetative propagation are a few examples of asexual processes (e.g. Onion).

Two identical 732. 0 l tanks each contain 212. 0 g of gas at 293 k, with neon in one tank and nitrogen in the other. Based on the assumptions of kinetic-molecular theory, rank the gases from low to high for each of the following properties.
The ideal gas law, also called the general gas equation, is the equation of state for a hypothetical ideal gas. It has some limitations, but is a good approximation of the behavior of many gases under many conditions. Given by:
PV = nRT
P = pressure
V = volume
n = amount of substance
R = ideal gas constant
T = temperature
Given
Volume of the tank = 732 L
Mass of the gas = 212 g
Temperature T = 293 K
Molar mass of nitrogen gas (N₂) = 28 g
Molar mass of neon (Ne) = 20 g
The average speed of the gases decreases with increase in weight of the gas. Thus, the neon gas will have the higher average speed.
To determine the gas that will have the higher pressure;
PV = nRT
where;
n = number of moles of gases
R = 0.0821 L atm / mol K
P = pressure of gas
T = temperature of gas ( 293 k)
[tex]n_{neon}[/tex] = 212/20
= 10.6 moles
[tex]n_{nitrogen}[/tex] = 212/28
= 7.57
[tex]P_{neon}[/tex] = (10.6 × 0.0821 ×293)/732
= 0.34 atm
[tex]P_{nitrogen}[/tex] = (7.57 × 0.0821 ×293)/732
= 0.24 atm
Thus, the pressure of the nitrogen gas will be the higher.
Collision frequency of the gases:
f = v/λ
[tex]v_{rms} = \sqrt{\frac{3RT}{M} }[/tex]
Where, M = molar mass
Collision frequency is inversely proportional to the molar mass
So, neon will have higher collision frequency due to its low molar mass.
Since, density is mass divided per volume.
Density = mass/volume
For the given case mass and volume for both the gases is same. Thus, density of both nitrogen and neon will be the same for the given temperature.

Two systems with identical Rate Laws but dissimilar initial concentrations are incompatible.
What is Rate Law?
A rate law demonstrates how the concentration of the reactant affects the rate of a chemical reaction. The rate law typically takes the form rate = k[A]n for a reaction like aA products, where k is the proportionality constant referred to as the rate constant and n is the order of a reaction with respect to A. The amount of n must be determined experimentally because it is unrelated to the reaction stoichiometry.
Rate Law= K × Cvc × Coh
Vc+OH
We use the abbreviation Vc for Voilet crystals.
Here, limiting reactant is (Vc) which is the violet crystals.
Cvc = initial Cvc × (1 - x)
Coh = initial Cvc × (1 - x)
Using these values in the 1st equation
Rate Law = K × Cvc × Coh
we get,
Rate Law = K × (Cvc 1)² × (1-x)²
This new equation demonstrates that the rate law depends on the initial concentration of the reagents.

where,
M₁ = molarity of stock solution = 12 M
V₁ = volume of stock solution = 15ml
M₂ = molarity of dilute solution = 6M
V₂ = volume of dilute solution = ?
substituting all the given values we get
M₁V₁=M₂V₂
12 M×15ml=6M×V₂
V₂=30ml
Therefore, volume of 12 M diluted solution of HCl is 30ml.
