How many grams of KNO3 will be produced if 150 grams of KI are allowed to react completely with lead nitrate
Use. 2KI + Pb(NO3)2 arrow 2 KNO3+PbI2
I got 91.4 g KNO3

91.27g

Explanation:

2KI + Pb(NO3)2 —> 2KNO3 + PbI2

Molar Mass of KI = 39 + 127 = 166g/mol

Mass of KI from the balanced equation = 2 x 166 = 332g

Molar Mass of KNO3 = 39 + 14 + (16x3) = 39 + 14 + 48 = 101g/mol

Mass of KNO3 from the balanced equation = 2 x 101 = 202g

Now we can obtain the mass of KNO3 produced as follows:

From the equation:

332g of KI produced 202g of KNO3.

Therefore, 150g of KI will produce = (150x202)/332 = 91.27g of KNO3

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.
