Acid rain can be destructive to both the natural environment and human-made structures. the equation below shows a reaction that occurs that may lead to the formation of acid rain. 3no2 + h2o mc025-1.jpg 2hno3 + no how many moles (precise to the nearest 0.01 mol) of nitric acid are produced from 300.00 mol of nitrogen dioxide?

Answer;

200.00 moles of nitric acid is produced

Explanation;

From the equation;

3NO2 + H2O → 2HNO3 + NO

The mole ratio of nitrogen (IV) oxide  and nitric acid is 3 is to 2;

Thus; for every 3 moles of nitrogen dioxide (NO2), 2 moles of nitric acid (HNO3) are formed. 

Therefore; 300 moles of NO2 will produce;

2 mol HNO3/ 3 mol NO2 (300) = 200 moles

Hence, 200 moles of nitric acid are produced from 300 moles of NO2. 

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:

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
