As the chemical reaction progresses, the interference pattern on the ceiling is moving to the right. This indicates that there is a change in the distance between the two slits that are creating the interference pattern. As a result, the value of n, which represents the number of fringes on the interference pattern, is changing as a function of time.
To determine whether n is getting smaller or larger, we need to consider the relationship between the distance between the slits and the spacing of the fringes on the interference pattern. According to the double-slit experiment, the spacing of the fringes on the interference pattern is given by the equation:
d*sin(θ) = mλ
where d is the distance between the slits, θ is the angle of diffraction, m is the order of the fringe, and λ is the wavelength of the light.
From this equation, we can see that the spacing of the fringes is directly proportional to the distance between the slits. This means that if the distance between the slits is increasing as the chemical reaction progresses, the spacing of the fringes will also increase. As a result, the value of n will get smaller, since there will be fewer fringes within a given distance.
On the other hand, if the distance between the slits is decreasing, the spacing of the fringes will also decrease, and the value of n will get larger, since there will be more fringes within a given distance.
Therefore, based on the information given in the question, we cannot determine whether n is getting smaller or larger without additional information about the specific changes in the distance between the slits.

(b) in what way are carbon dioxide and orange juice similar?
Answer:
The effects of supercritical CO2 (SC-CO2) on the microbiological, sensory (taste, odour, and colour), nutritional (vitamin C content), and physical (cloud, total acidity, pH, and °Brix) qualities of orange juice were studied. The CO2 treatment was performed in a 1 litre capacity double-walled reactor equipped with a magnetic stirring system. Freshly extracted orange juice was treated with supercritical CO2, pasteurised at 90°C, or left untreated. There were no significant differences in the sensory attributes and physical qualities between the CO2 treated juice and freshly extracted juice. The CO2 treated juice retained 88% of its vitamin C, while the pasteurised juice was notably different from the fresh juice and preserved only 57% of its vitamin C content. After 8 weeks of storage at 4°C, there was no microbial growth in the CO2 treated juice.

Find the percent composition of chromium(|||) fluoride (CrF3), which is commonly used as a dye in textiles
Answer:
%Cr = 47.71%
%F = 52.29%
Explanation:
To do this, we need the atomic weights of all the elements in the chromiun fluoride, which are the following:
Cr: 51.996 g/mol
F: 18.998 g/mol
With these atomic weights, let's calculate the molecular mass of the chromium fluoride:
MM CrF₃ = (51.996) + (18.998 * 3) = 108.99 g/mol
Now, to get the percent composition, all we have to do is divide the atomic weight of each element by the molecular mass, and then, multiply by 100%:
% = (AW / MM) * 100
Replacing with each element:
%Cr = (51.996 / 108.99) * 100
%Cr = 47.71%%F = 100 - 47.71
%F = 52.29%Hope this helps
Denise was driving east over a hill in the afternoon, shortly after a rain shower. Suddenly the sun broke through the clouds, and she saw a rainbow ahead of her. Which of the following made the rainbow possible?
Answer: A. Raindrops act like a prism and separate the white light in sunlight.
Explanation:
The reason for the formation of rainbow is option A. Raindrop acts like a prism and separate the white lite into different colors.
What is rainbow?Rainbow is an arc of colors from a white light ray which can be formed by the separation of component colors from white light by the combination of reflection, and refraction.
White light absorbs all colors and reflect all of them. That is why a white object is seen white the mix of all colors. When the white light passes through a raindrop, it gets refracted, the refracted light then reflects from the drop and undergo one more refraction and that make the component colors in the form a bent or arc.
Therefore, raindrop is acting like a prism to separate the white light into its component colors. Hence, option A is correct.

The water cycle describes the movement of water on Earth. Water in oceans and lakes evaporates and turns into water vapor. This water vapor condenses and forms clouds which produce precipitation. Precipitation falls all over the Earth's surface. The water eventually comes back to the oceans through run-off. Which steps in the water cycle carry water out of an ocean and into a freshwater lake?
A. Evaporation and precipitation
B. Rivers and streams
C. Underground tunnels
D. Condensation and run-off
Answer:
c. Underground tunnels
Explanation:
Yes, water below your feet is moving all the time, but, no, if you have heard there are rivers flowing below ground, that is not true. Water moves underground downward and sideways, in great quantities, due to gravity and pressure. Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going.
Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.
The steps in the water cycle that carries water out of the ocean into a freshwater lake are rivers and streams.

A thermochemical equation indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by a triangle H does this term stand for?
Answer:
A. Enthalpy of the reaction
Explanation:
A Thermochemical equation is a balanced stoichiometric chemical equation that indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by ΔH, a this term which stands for the enthalpy change, ΔH.
The Enthalpy of Reaction or Heat of Reaction is the amount of energy in the form of heat transferred during a chemical reaction that occurs at a constant pressure. It is useful for calculating the amount of energy per mole either released or produced in a reaction, therefore is unit is kJ/mol.
In a reaction where energy is absorbed by the reactants during the formation of products, ΔH is positive. On the other hand, in a reaction where energy is released by the reactants during the formation of products, ΔH is negative.
The enthalpy change, ΔH of reactions are determined experimentally under standard conditions of 1 atm and 25 °C (298.15K). Enthalpy can be measured experimentally through the use of a calorimeter. A calorimeter is an isolated system which has a constant pressure and in which heat loss to the surroundings is minimal.

Answer:
406m/s
Explanation:
Speed = distance ÷ time
Answer:
406 m/s
Explanation:
Divide 325,000 meters by 800 and 800 seconds by 800 (because we are trying to find the speed in meters per second.
325,000÷800 = 406.25 meters

20.What do carbon and silicon have in common?
a.They belong to the same column (family), therefore they have the same number of valence electrons.
b.They belong to the same column (family), therefore they have the same number of total electrons.
c.They belong to the same column (family), therefore they have the same number of energy levels.
d.They belong to the same column (family), therefore they have the samenumber of protons.
The carbon and silicon have in common that they belong to the same column (family), therefore they have the same number of total electrons. So, option B is correct.
What do carbon and silicon have in common?Carbon's closest analogue is silicon. Silicon and carbon are both tetravalent atoms that primarily form covalent (non-ionic) compounds. However, aside from the fact that both elements "can form four covalent bonds," there is surprisingly little in common between them.
Carbon has an atomic number of 6 and an electronic configuration of 2, 4. Silicon has an atomic number of 14 and an electronic configuration of 2, 8, 4. Because both elements have the same number of valence electrons, they are classified as being in the same group.
Thus, option B is correct.
