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.

Answer:

the answer is adaptations

Explanation:

A body part or behavior that helps an animal meet its need in its environment is called an adaptation. All adaptions are inherited traits. Camouflage is an animal's color or pattern that help it blend in with its surroundings.

Answer:

Its C

Explanation:

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.

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.

conductivity in solid state/ in water

Explanation:

conducitvity in water state would be least helpful when trying to determine the bond type that has the strongest intermolecule force, becuase they (salt and water) both would dissolve in water the same.

The property that will be least helpful in the determination of the bond type that has the strongest intermolecular forces is C. Conductivity in water.

It should be noted that the students wanted to investigate whether ionic or covalent bonds have stronger intermolecular forces.

In order to carry out the investigation, salt, sugar, and molar balls are used. Based on this, the property that is required for the investigation will be flammability, solubility in water, and the melting point.

The conductivity in water isn't required.

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]

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

Answer:

Boron

Explanation:

First, locate the metalloids on the periodic table. (First picture) The metalloids are in the yellow section. Next, remember that the group your element is in determines its valence electrons. For example, group 17/7A has 7 valence electrons. Look at the group numbers above each column on the periodic table to find out which metalloid is the answer. In this case, we need to look at 13/3A since we know that this metalloid has three valence electrons. Not all  periodic tables will be labeled with the 3A part, so remember that groups 13 and over have the amount of valence electrons after you take out the one in front. For example, group 16 has 6 valence electrons because I removed the one in front of it. Now your options should be limited down to boron because we know that it is in the yellow section in group 13.
