How many grams of chlorine gas must react to give 3.52g of bicl3 according to the equation in exercise 23? 2bi+> 2bicl3

The correct answer is 1.19 g of chlorine.

The following reaction is:

2Bi (s) + 3Cl₂ (g) ⇒ 2BiCl₃ (s)

In the reaction, it can be witnessed that 3 mol Cl₂ is equal to 2 mol BiCl₃

The molecular weight of BiCl₃ = 315.33

Thus,

3.52 g BiCl₃ = 3.52 g BiCl₃ × 1.00 mol BiCl₃ / 315.33 g BiCl₃

= 0.0112 mol BiCl₃

The mole ratio of Cl₂ and BiCl₃ is,

3 mol Cl₂ / 2 mol BiCl₃

Therefore, the amount of chlorine needed to form 0.0112 mol BiCl₃ is,

0.0112 mol BiCl₃ × 3 mol Cl₂ / 2 mol BiCl₃ = 0.0168 mol Cl₂

Now, the molecular weight of Cl₂ = 70.90

Thus,

0.0168 mol Cl₂ = 0.0168 mol Cl₂ × 70.90 g Cl₂ / 1.00 mol Cl₂

= 1.19 gm Cl₂

Hence, in the mentioned reaction, there is a need of 1.19 g of chlorine to react to produce 3.52 g of BiCl₃.

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.
