d[O] dt = d[O3] dt =0 (7) we can solve for [O] and [O3]
What is the Lindemann-Hinshelwood mechanism?
The unimolecular processes that take place in the gas phase are explained by the Lindemann-Hinshelwood mechanism. This method is typically employed in both isomerization reactions and gas phase breakdown. The isomerization of cyclopropane is an illustration of isomerization through a Lindemann mechanism.
The steady state approximation makes the assumption that, after a brief initial period, the concentration of the chemical intermediates will be constant throughout time, meaning that the rate of change in the intermediate's concentration over time will be zero.
Thus by steady state concentration,
d[O] dt = d[O3] dt =0 (7) we can solve for [O] and [O3]

Acid Rain: What Is It?
Any type of precipitation that contains acidic elements, such as sulfuric or nitric acid, that falls to the ground from the atmosphere in wet or dry forms is referred to as acid rain, also known as acid deposition. Rain, snow, fog, hail, and even acidic dust might fall under this category.
Only one variable—the acidity level of the rainfall over a specific time period—will be present in the data used to create the plot or graph. But because the gbwre data is time-dependent, the plot is a time series. As a result, this is a two-dimensional univariate plot with time on the other axis and the acidity label Rainfall on the first. The time series plot is therefore the appropriate type of graph to use to illustrate this kind of data.

% yield of SnS2 = 0.337 X 100 / 0.567 = 59.44 %
% yield of SnS2 = 59.44 %
Balanced chemical reaction is
SnBr4(aq) + 2Na2S(aq) ---> 4NaBr(aq) + SnS2(s)
First calculate limiting reactant
molarity of SnBr4 = 0.418 M
volume of SnBr4 = 0.0451 L (1 ml = 0.001 L then 45.1 ml =45.1 X 0.001 = 0.0451 L)
molarity of Na2S = 0.133 M
volume of Na2S = 0.0466 M ( 1 ml = 0.001 L then 46.6 ml =46.6 X 0.001 = 0.0466 L)
no.of moles = molarity X volume of solution in liter
moles of SnBr4 = 0.418 X 0.0451 = 0.0189 mol
moles of Na2S = 0.133 X 0.0466 = 0.0062 mol
According to balanced chemical reaction 1 mole of SnBr4 react with 2 mole of Na2S molar ratio between SnBr4 to Na2S is 1:2 therefore to react with 0.0189 mole of SnBr4 required Na2S = 0.0189 X 2 / 1 = 0.0378 moles Na2S but Na2S given only 0.0062 mole therefore Na2S is limiting reactant
Limiting reactant = Na2S
According to balanced chemical reaction 2 mole of Na2S produce 1 mole of SnS2 molar ratio between Na2S to SnS2 is 2:1 therefore 0.0062 mole of Na2S produce SnS2 = 0.0062 X 1 / 2 = 0.0031 moles
Mole of SnS2 produced = 0.0031 mole
Molar mass of SnS2 = 182.81 g/mol
Gm of compound = no. of moles X molar mass
Gm of SnS2 formed = 0.0031 mol X 182.81 g/mol = 0.567 g
Gm of SnS2 formed = 0.567 g
Theoretical yield of SnS2 = 0.567 g
Actual yield of SnS2 = 0.337 g
Theoretical yield of SnS2 = 0.567 g
% yield = Actual yield X 100 / theoretical yield
Substitute the value
% yield of SnS2 = 0.337 X 100 / 0.567 = 59.44 %

1. Sally's average speed is 35.38 miles/hr. She deserves no ticket
2. The 20.0 ft tall building is 6096 mm tall.
Miscellaneous calculationFor the first problem, recall that: speed = distance/time.
The distance covered by Sally is 97 km within 102 minutes.
1 km = 0.62 miles
97 km = 0.62 x 97
= 60.14 miles
60 minutes = 1 hr
102 minutes = 102/60
= 1.7 hours
The average speed of Sally can be calculated as:
60.14/1.7 = 35.38 miles/hr
Since the speed limit is 65 mi/hr, this means Sally's speed is still within acceptable limits and does not deserve a ticket.
For the second problem:
1 ft = 12 inches
20 ft = 12 x 20
= 240 inches
1 inch = 2.54 cm
240 inches = 2.54 x 240
= 609.6 cm
1 cm = 10 mm

As we increase the temperature of the material, the kinetic energy of the particles that make the material increase (thus the speed increases). This causes the particles to move more, and this is why as we increase the temperature, is likely to see an increase in the volume.
Then as we increase the temperature of liquid water and that water starts to change of phase (by boiling) the kinetic energy of the particles increase, and thus, the speed increases. then the particles will be moving faster than the particles of the water in the pan.

One of the most profound ideas proposed by Max Planck was
O electrons constantly emit light.
O special relativity.
O electron energies are quantized
O atoms follow the "plum pudding" model
According to the research, the correct option is electron energies are quantized. Max Planck was a popular German physicist who proposed that electron energies are quantized, considered to be the founder of quantum theory.
What is quantum theory?It is a probabilistic and quantification theory by Max Planck giving the name of the minimum amount of clusters to atoms that radiates energy formed by corpuscles in the form of light or heat only, as small packets.
In this sense, Planck assumed that light does not travel as a particle but as packets of light in the form of electromagnetic radiation which he called quanta, this was the basis on which what is known as quantum theory was founded.
Therefore, we can conclude that according to the research, the correct option is electron energies are quantized. Max Planck was a popular German physicist who proposed that electron energies are quantized, considered to be the founder of quantum theory.

if all of this coal is burned how much co2 will be emitted into the atmosphere? how much will this increase the co2 content of the atmoshphere in ppm?
coal is burned and co2 will be emitted into the atmosphere.
What is ppm?
PPM, or parts per million, is the most effective way to express the level of performance or chemical concentration in a bigger mixture. This could be used to describe the components of water, the faulty rate of a provider, etc. Being a ratio of two quantities of the same unit, it is theoretically a dimensionless measure that is represented as a percentage and is better suited to representing lesser concentrations of chemicals in gases, liquids, or solids.
When a coal is burned, it releases a certain amount of carbon dioxide (CO2) in relation to the energy it produces. Compare the quantity of CO2 released per unit of energy output or heat content to compare emissions across fuels.

In an aqueous solution of ch3br, what is the strongest intermolecular force between ch3br and water?
Dipole-dipole interactions between H2O molecules produce the greatest intermolecular forces in a molecule.
What does the term "dipole" mean?It simply refers to a line made up of two wires, each of which is connected to a power outlet using a negative and positive signal. When a dipole appears, several atoms may have the same ionization spectrum or may be split into negative and positive regions. Both partial negative (-ve) and partial positive (+ve) signs are used to denote it.
What impact does a dipole have on a molecule's polarity?A molecule's form affects polarity. Due to the 2 OH bonds and the consequent dipole, the molecule with 2 lone pairs, such as water, is very polar. The vector sum of the various polar bonds produces the dipole.
