Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass
Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population,
mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
By removing long-buried fossil fuels and burning them to produce electricity, human activities have drastically disrupted the natural carbon cycle and released CO2 into the atmosphere. The burning of fossil fuels like coal, natural gas, and oil, including gasoline, is responsible for 85% of all human-produced carbon dioxide emissions.
reductions in atmospheric oxygen concentration and the proportion of other carbon isotopes (14C and 13C) have been observed. Because the natural mechanisms that may restore the balance are too slow relative to the rates at which human activities are adding CO2 to the atmosphere, the extra CO2 from burning fossil fuels and deforestation has upset the equilibrium of the carbon cycle. As a result, a sizeable portion of the CO2 produced by human activity builds up in the atmosphere, where part of it will stay for thousands of years rather than just a few decades or centuries.

Explanation:
The highest number is the strongest base. Therefore the pH of 12 is the strongest base here (C).
CaCl2 has a stronger ionic bond than KCl because Ca+2 is smaller than K+ in size.
<h3>What is the working of ionic bonds ?</h3>
A stable link formed by the complete transfer of the valence electron is known as an ionic bond. This kind of interaction results in the formation of positive ions, also known as cations, and negative ions, also known as anions.
- This kind of interaction is exemplified by the ionic bond in sodium chloride, a salt. The sodium valence electron is transferred to the outer electron shell of chloride. Ionic molecules form the basis of ionic compounds.
- The three types of bonds that frequently develop are covalent bonds between nonmetals, ionic bonds between metals and nonmetals, and metallic connections between metals.

<span>Bases can both take up hydrogen ions and release hydroxide ions. This differs from an acid, which releases a hydrogen ion. Combining acids and bases can produce a lot of heat during the reaction. If the acid and base are of the same strength, the mixture will be neutralized.</span>
