Based on Arrhenius theory, explain why CaCI2(aq) can be considered a neutral solution rather than an acidic solution or a basic solution?

Another question is in an experiment ammonia has, NH3(aq) reacted with the water to form the aqueous ammonia ions, NH4+(aq). When red litmus paper was placed in contact with the aqueous solution the paper turned blue. This indicated a basic solution.

a. Identify the acid and the base in the reaction between dissolved ammonia gas, Nh3(aq) and water. Explain your answer

B. Identify the conjugate acid and the conjugate base of the reaction. Explain your answer

C. Write the complete chemical equation for the reaction between NH3(aq) and H2O(I)

Another question is: The oxides is carbon, sultry and nitrogen can be harmful when released into the atmosphere. Why are these oxides so harmful. Give one reason that applies to all these oxides?

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
