The reaction order is given as the relationship between the concentrations of the reactants and the rate of a reaction.
The order of a rate law is the sum of the exponents of the concentration of the reactants.The rate law of a reaction is used to understand the composition of the reaction mixture. Specifically, the reaction order is the exponent to which the concentration of that reactants are raised, and it indicates that how well the concentration of a reactants affects the rate of a reaction.There are number of methods used to determine the reaction order. Reaction orders not always equal to the coefficients in a balanced chemical equation , it only determined the number of molecules per mole present in a given reaction.Learn more about order of reaction here..

The carbocation stabilized by resonance structure and thereby lowers the energy of the carbocation, hydrogen will add to the carbon in the double bond that produces delocalization of electrons.
What is carbocation?A carbocation is a molecule in which a carbon atom has a positive charge and three bonds.
In general, electrons are stabilized by delocalization. The stabilization energy engendered by delocalization over more than two atoms is called the resonance stabilization energy or simply the resonance energy. The greater the extent of electron delocalization the greater the resonance stabilization.

PLEASE HELP FAST! When 23.3 g of O2 reacts with 18.3 g C10H8, what is the limiting reactant. The equation is C10H8 + 12O2 --> 10CO2 + 4H2O?
Choices:
A. C10H8
B. O2
C. CO2
D. H2O
Answer:
B
Explanation:
The answer is B, O2
O₂ is the limiting reagent.
What is a limiting reactant?A limiting reactant is described as the one that will be consumed first in a chemical reaction.
CalculationC₁₀H₈ + 12O₂ → 10CO₂ + 4H₂O
Given, Mass of O₂ = 23.3 g
Mass of C₁₀H₈ = 18.3 g
Molar mass of O₂ = 32 g
No. of moles of O₂ = 32/23.3 = 1.4 moles
Molar mass of C₁₀H₈ = 128 g
No. of moles of C₁₀H₈ = 128/18.3 = 6.9 = 7 moles
According to the equation,
1 mole of C₁₀H₈ yields 10 moles of CO₂. So, 7 moles of C₁₀H₈, give 70 moles of CO₂.
12 moles of O₂ yields 10 moles of CO₂. So, 1.4 moles of O₂ give 1.16 moles of CO₂.
We do know, however, that based on our balanced equation, if we were to totally react all 1.4 moles of O2, we could only produce a maximum of 1.16 moles of CO2. Even while there is enough C10H8 to generate more, the amount of O2 we have is a limiting factor because it will be consumed first.
So, our limiting reactant is O₂.

Record the amount of sodium chloride that
dissolved.
Ionic compounds such as sodium chloride, which dissolve in water and dissociate to form ions, are called electrolytes.
What are electrolytes?Electrolytes are substances that have a natural positive or negative electrical charge when dissolved in water.
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Planck's constant is 6.626 x 10-34 J.s.)
400
750 pm
Answer:
C.) 4.85 x 10⁻¹⁹ J
Explanation:
To find the energy, you need to use the following equation:
E = hc / w
In this formula,
-----> E = energy (J)
-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)
-----> c = speed of light (3.00 x 10⁸ m/s)
-----> w = wavelength (m)
Once you have converted nanometers to meters, you can plug the given values into the equation and solve.
410 nm 1 m
------------- x ---------------------- = 4.10 x 10⁻⁷ m
1 x 10⁹ nm
E = hc / w
E = (6.626 x 10⁻³⁴ J*s)(3.00 x 10⁸ m/s) / (4.10 x 10⁻⁷ m)
E = 4.85 x 10⁻¹⁹ J
A student spilled a bottle of ammonia in one corner of the laboratory. Soon the whole laboratory was felled with pungent irritating small. The students immediately opened the windows and doors and switched on the exhaust fans. After sometime, students got relief. Explain what did actually happen?
Answer: Initially when the student spilled the bottle of ammonia the ammonia gas particles diffused with the particles of air in the room. We know that the rate of diffusion of gases is very high. So the entire room filled up with the pungent smell of ammonia.
When he opened the doors and windows and switched on the exhaust fan, the air from the room along with the ammonia gas diffused with the air outside the room.Moreover, outside air entered into the room so the concentration of ammonia gas in the room air reduced.Due to these reasons the student got relief.
