Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction:
2al(s)+3cl2(g)→2alcl3(s)
you are given 10.0 g of aluminum and 15.0 g of chlorine gas. if you had excess chlorine, how many moles of of aluminum chloride could be produced from 10.0 g of aluminum?

0.3706 moles of aluminum chloride would be produced from 10.0 g of aluminum

Explanation:

chemical equation:

2Al(s) + 3Cl2(g) → 2AlCl3(s)

Given data:

mass of aluminium = 10 g

mass of chlorine = 15 g

First of all we will calculate the moles of each reactant:

moles of aluminium= 10 g/ 26.98 g/mol

moles of aluminium= o.3706 mol

moles of Cl2 = 15 g/ 10.90 g/mol

moles of Cl2 = 0.2116 mol

now we compare the moles aluminium with aluminium chloride

    Al     :  AlCl3

    2     :    2

    1      :     1

0.3706  :    0.3706

now we compare the moles chlorine with aluminium chloride

    Cl    :   AlCl3

     3    :      2

 0.2116  :   2/3× 0.2116 = 0.1412 mole

although chlorine is limiting reactant but in question we are given excess chlorine so 10 g of aluminium will produce 0.3706 moles of aluminium chloride.

mass of AlCl3 = 0.3706 mol × 133.34 g/mol

mass of AlCl3 = 50.13 g

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:

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
