Carbonated beverages contain dissolved carbon dioxide gas. Low temperatures are best to minimize the solubility. option C is correct.
Drinks that have carbon dioxide dissolved in the water are referred as carbonated beverages. The presence of this gas causes the liquid to froth.
Carbonation takes place by applying pressure. Spring water, beer and soda, and pop are a few examples of carbonated beverages. When carbon dioxide is absorbed in a liquid, for example spring water, it absorbs Carbon dioxide from the subsurface. It can also happen naturally. Beer is example of a naturally carbonated beverage as the brewing process produces carbon dioxide soda .
Thus option C is correct.

why are ionic solids brittle
Answer:
-The ionic solids are hard and brittle because the ions in ionic solids are held in a lattice due to the electrostatic forces of attraction in cations and anions as well as the repulsion with the like charges. ... Because the ionic solids are localized, these solids tend to be stiff and brittle like covalent solids.
Explanation:
What pressure is required to achieve a CO2 concentration of 0.0620 mol L−1 at 20∘C?
Considering the definition of ideal gas law, a pressure of 1.5 atm is required to achieve a CO₂ concentration of 0.0620 mol L⁻¹ at 20°C.
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P×V = n×R×T
So the pressure is calculated as:
[tex]P=\frac{n}{V}xRxT[/tex]
In this case, you know:
[tex]\frac{n}{V} = 0.0620 \frac{mol}{L}[/tex]R= 0.082 [tex]\frac{atmL}{molK}[/tex]T= 20 C= 293 KReplacing:
P=0.0620 [tex]\frac{mol}{L}[/tex]× 0.082 [tex]\frac{atmL}{molK}[/tex]× 293 K
Solving:
P= 1.489612 atm≅ 1.5 atm
Finally, a pressure of 1.5 atm is required to achieve a CO₂ concentration of 0.0620 mol L⁻¹ at 20°C.

Aeration basins increase the rate of bacteria working to break down the organic matter in wastewater. True or False?
Answer:
it is true
Explanation:
Aeration basins increase the rate of bacteria working to break down the organic matter in wastewater is true.
What is aeration basins?Aeration basins is defined as the biomass consumes both oxygen and organic pollution, resulting in net microorganism growth and carbon dioxide release.
It can also be defined as the process of introducing air into wastewater in order to allow aerobic bio-degradation of pollutant components.
Aeration is frequently used to reduce the amount of carbon dioxide released by a treatment process.
It is the best methods for waste water treatment .
The main disadvantage of the aeration process is that too much oxygen is absorbed and the water becomes corrosive.
Thus, aeration basins increase the rate of bacteria working to break down the organic matter in wastewater is true.

If you have 460 grams of H2o, how many molecules are present?
How is thermal energy transferred by convection, conduction, and radiation?
Answer:
Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but at a much slower rate. Heat transfer by convection also occurs through cold air entering the room around windows and hot air leaving the room by rising up the chimney.
When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. ... A space heater is a classic convection example.

When solid sodium hydroxide is dissolved in water,the temperature of the soution formed rapidly increases. a) compare the total energy of the solid NaOH with that of the solution and state which is greater.
Answer: In a perfectly isolated system, the total energy is the same.
Explanation: The conservation laws for mass and energy hold in a system that is isolated from its surroundings. The enegy released by the dissolution of solid NaOH in water is absorbed by the water. So the total energy of the syetm remains the same. It is simply converted from lattice energy of the NaOH into heat energy as measured by the temperature of the water. As long as it is operfectly isolated, the total energy remains the same.

Answer:
red because its the flavor
Explanation:
Use the following image to answer the following questions. A student was performing an experiment using two identical cups made of styrofoam. The student had Cup A holding water at 90℃ and Cup B holding water at 20℃. The student then put an Aluminum Bar into each cup that was touching the water. As time passed, the student noticed that the temperature of the water in Cup A and Cup B began to change. Question:
A. Predict what will happen to the temperature of the water in Cup A and Cup B after 1 hour has passed. (1 point)
B. Explain and give evidence for what type of heat transfer is occurring between the 2 cups.
In cup A, the temperature of the water will drop after 1 hour and the temperature of the aluminium will rise. In cup B, there will be no change in temperature of the water and the aluminium. The type of heat transfer taking is conduction.
When two bodies at different temperatures come into contact which other. Heat is transferred from the hotter body to the cooler body until thermal equilibrium is achieved between the two bodies. The temperature of the water decreases while that of the aluminium bar rises.
The aluminium bars were put into the two cups holding water at 90℃ and 20℃ respectively. Since the water in cup A is at a higher temperature than the aluminium, heat is transferred from the water to the aluminium bar until thermal equilibrium is achieved.
In cup B, there is no temperature difference between the water and aluminum hence no heat transfer occurs. Note that a mode of heat transfer that depends on temperature difference between two bodies in contact is conduction.
