How does panting help the dog maintain homeostasis?
Panting helps the dog maintain homeostasis because panting is the equivalent of humans sweating. Dogs pant to cool themselves down to reachieve their "normal" body temperature. Homestasis is the individuals sense of equilibrium and a dog panting helps them to acheive their temperature homeostasis.
An unknown gas has a volume of 20L at 140K. What is its volume at STP? Be sure to show the setup and the final
answer and unit.
Show Your Work
Answer:
v₂ = 39L
Explanation:
Given parameters:
Initial volume of gas = 20L
Initial temperature = 140K
Unknown:
Final volume = ?
Solution:
Since the standard temperature of any gas is 273K, the final temperature is this 273K;
Applying Charles's law:
[tex]\frac{v_{1} }{T_{1} }[/tex] = [tex]\frac{v_{2} }{T_{2} }[/tex]
v and T are volume and Temperature
[tex]\frac{20}{140}[/tex] = [tex]\frac{v_{2} }{273}[/tex]
v₂ x 140 = 20 x 273
v₂ = 39L

Given the speed of light as 3.0 ✕ 108 m/s, calculate the wavelength of the electromagnetic radiation whose frequency is 6.700 ✕ 1012 Hz.
Answer:
Wavelength = [tex]4.48*10^{-5}m[/tex]
Explanation:
Given the following data;
Speed of light, V = 3 * 10^{8}m/s
Frequency, F = 6.700 * 10^{12}Hz.
To find the wavelength
We know that that the speed of light is given by the formula;
[tex] Speed of light, V = wavelength * frequency [/tex]
Making wavelength the subject of formula, we have;
[tex] Wavelength = \frac {speed \; of \; light}{frequency} [/tex]
Substituting into the equation, we have;
[tex] Wavelength = \frac {3 *10^{8}}{6.700 ✕ 10^{12}} [/tex]
Simplifying the equation, we have;
Wavelength = 4.48*10^{-5} m
Therefore, the wavelength of the electromagnetic radiation is [tex]4.48*10^{-5} meters[/tex]

Explanation:
44 gm mass of carbon dioxide is produced by the decomposition.
What is meant by Decomposition reaction?
Chemical species disintegrate into more straightforward components during decomposition events. Energy input is typically required for decomposition reactions.
For instance, the thermal breakdown of potassium chlorate (KClO3) is a typical method for creating oxygen gas in laboratories.
Calculations:
CaCO3 → CO2 + CaO
depending on the conservation of mass
mass of the product = mass of the reactant
100 g = ( X + 56 )
mass of CO2 = 100 - 56
= 44 g
Thus, 44 gm mass of carbon dioxide is produced by the decomposition.

carbon dioxide and water vapor are variable gases because
Answer:
Their amount is not consistent at all parts of the atmosphere
Explanation:
Carbon dioxide and water vapor exists as variable gases in the atmosphere because their amount varies from one part to the other.
The abundance of variable gases is influenced strongly by activities from the surface. This variability occurs a result of the contribution from from life activities on the surface. Also, due to properties of the gases, they are not evenly distributed. At certain altitudes, the amount of water vapor can be low.Carbon dioxide and water vapor are variable gases because their amount is not consistent at all parts of the atmosphere.
Surface activities have a significant impact on the abundance of variable gases.This variation arises as a result of the input of surface life activities.They are also not uniformly dispersed due to the characteristics of the gases.Water vapor levels might be low at particular heights.Carbon dioxide and water vapor are variable gases because their amount is not consistent at all parts of the atmosphere.For more information:

What can you do to help reduce Acid Rain? List 5 ways.
Help me yall!! Imao
Answer:
- to produce energy without using fossil fuels instead using renewable sources solar and wind power.
- reduce the amount of sulfur dioxide released from coal-burning power plants. One option is to use coal that contains less sulfur.
- install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.
- While one car alone does not produce much pollution, all the cars on the road added together create lots of pollution. Therefore, car manufacturers are required to reduce the amount of nitrogen oxides and other pollutants released by new cars. One type of technology used in cars is called a catalytic converter. This piece of equipment has been used for over 20 years to reduce the amount of nitrogen oxides released by cars.
- recycling is one way that is often use less energy than producing a new products from raw materials so the use of energy that obtain mainly from fossil fuel will be reduced and that reduced the emissions of toxic gases.
Decreasing the amount of sulphur dioxide power plants that burn coal emit and Using less sulfuric coal is one option to reduce acid rain.
What is acid rain?Acid rain, also known as acid precipitation and acid deposition, is a type of precipitation with a pH of 5.2 or below that results from the release of nitrogen oxides and sulphur dioxide (SO2) from human activities, primarily the burning of fossil fuels. Acid deposition can impair biodiversity and lower the pH for surface waters in acid-sensitive areas.
To reduce acid Rain following steps can be taken: Generate energy using renewable resources like solar and wind energy rather than fossil fuels. Decrease the amount of sulphur dioxide power plants that burn coal emit. Using less sulfuric coal is one option. Install machinery known as scrubbers to take sulphur dioxide out of smokestack gas emissions. New automobiles must emit fewer nitrogen oxides as well as other pollutants, according to regulations for automakers. One method that frequently uses less energy than creating new items from basic materials is recycling.
Therefore, decreasing the amount of sulphur dioxide power plants that burn coal emit and Using less sulfuric coal is one option to reduce acid rain.

Which statement correctly describes a reaction in dynamic equilibrium? At dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change. At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change. At dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing. At dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.
Answer:
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
Explanation:
At dynamic equilibrium, the reactions continue but according to the law of conservation of mass, the amounts of reactants and products don't change.
At dynamic equilibrium, the reactions takes place, however, the amount of reactants and products do not change.
• Dynamic equilibrium prevails once a reversible reaction takes place.
• In this the transition of the substances between the reactants and products takes place at equivalent rates, thus, there is no net change.
• The formation of products and reactants takes place at such a rate that the concentration of both stays the same.
• It is an illustration of a system in steady state, like in a closed system when reactions do take place, however, at such a rate that the composition of the mixture does not varies with time.
Thus, the statement, that is, at dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change is relevant.
