The natural resource that is renewable is wind. Therefore, option B is correct.

Renewable resources are natural resources that can be restocked or regenerated over a relatively short period of time, usually within a human lifetime. These resources are often contrasted with non-renewable resources, such as fossil fuels, which take millions of years to form and are finite in quantity.

Examples of renewable resources include solar energy, wind energy, hydroelectric power, geothermal energy, biomass, and tidal power.

These resources have the potential to provide energy and other materials indefinitely if used sustainably, making them an important part of efforts to move towards a more sustainable future. Therefore, option B is correct.

Explanation:

Answer:

Answer is 10.398(approx.)

Explanation:

NaOH ⇄ Na⁺ + OH⁻

pOH = -log[OH⁻]= -log(2.5×10⁻⁴) = 3.602

∴pH = 14 - pOH = 10.3989(approx.)

Answer:

boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature

in case of water boiling point bring 0 degree

Answer:

it is the temperature at which water starts to boil. the temperate is 100°C or 212°F

The correct answer is: It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can

decrease acidity, while the carboxyl group can increase acidity.

The carboxyl functional group is acidic while the amine group is basic.

In an amino acid, there are two functional groups;

The carboxyl functional group is acidic because it contains a replaceable or  ionizable hydrogen ion. The amine group on the other hand is capable of accepting a proton hence it is basic.

Therefore, In a solution, the amine group can  decrease acidity, while the carboxyl group can increase acidity.

Answer:

20,40,60

Explanation:

Let the three parts be 1x, 2x and 3x

The the sum of three parts will be 1x+2x+3x = 120

6x=120

x=120/6

x=20

1x= 20x1=20

2x= 20x2=40

3x= 20x3=60

So 120 is divided in three parts that is 20,40,60

Answer: An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.  

Exothermic reactions are important to forensic sciences and particularly to fire and explosion investigation. When a chemical reaction requires heat (rather than producing it) and results in cooling down the surroundings, it is conversely called endothermic.

Example-  

Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.

Answer:

sublimation. During this process, naphthalene being sublime changes into vapours leaving behind impurities. Vapour can be cooled by condensation. This process is very helpful in separating a volatile solid from a non-volatile solid.

Answer:

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.

Explanation:

The levels of carbon dioxide in the atmosphere are estimated to be higher than at any time in the past 420,000 years. That is option B

Carbon dioxide is a very harmful compound which is easily released into the atmosphere through burning of fossil fuels and other carbon compounds in plenty of air.

The released carbon dioxide rises to the upper atmosphere and blocks the radiation of solar energy back into the space. This precipitates a global temperature increase called the greenhouse effect.

According to Intergovernmental Panel on Climate Change (IPCC) in a current research discovered that CO2 concentration in the earth’s atmosphere is higher than at any point during the last 650,000 years. They where able to study this through the study of higher levels of CO2 concentration which coincide with higher temperatures.

Therefore the correct option is B which states that the levels of carbon dioxde in the atmosphere are estimated to be higher than at any time in the past 420,000 years.

Explanation:

Physical changes only change the appearance of a substance, not its chemical composition.

Chemical changes cause a substance to change into an entirely substance with a new chemical formula.

Chemical changes are also known as chemical reactions. The “ingredients” of a reaction are called reactants, and the end results are called products
