Under the right conditions aluminum will react with chlorine to produce aluminium chloride.

Chemistry
1 answer:
Andreas93 [3]3 years ago
5 0

Answer:

Ok

The Limiting reagent is Aluminum. Its not in excess. So the reaction ends once its exhausted. So all Aluminum will be used up

From the question ....

157g of Al

Find the number if reacting Moles...

M=mass/molar mass

M= 157/27

=5.81moles of Aluminum is reacting.

Now looking at the equation of reaction(Always make sure its balanced)...

2moles of Al react to produce 2 Moles of AlCl3

Their Mole ratio is equal

Since their Mole ratio is equal 2:2.... That means... That 5.81moles of AlCl3 would be produced because the mole of Al is 5.81

So We now know the Moles of AlCL3 produced

getting the Mass won't be difficult.

Again

Mole=Mass/Mm

Mass = Mole x Mm(Molar Mass)

Mass of AlCl3 = 5.81 x (27 + 35.5x3)

Note: The arithmetic done in the parenthesis is the molar mass of AlCl3

Mass of AlCl3 = 5.81 x 133.5

=775.63g of AlCl3.

Have a great Day!!!!

Given the following reaction: H2SO4+2LiOH=Li2SO4+2H20, what mass of water is produced from 19 g of sulfuric acid?
goldfiish [28.3K]

Hi,

To solve the question, first of all we will find out the no. of moles of H2SO4 in  19 g of sulfuric acid.

As we know:

              No . of moles = Mass/ Molar mass

              No. of moles= 19 g/98.08 g

               No. of moles= 0.1937

Now we know the no of moles of H2SO4 that will react with 2LiOH. We also know the  molar equivalence of H2SO4 , and 2LiOH that will react.

So, the  water that will be produced will be 2H2O and 1 Li2SO4 when H2SO4 that will react with 2LiOH.

                          0.1937 x 2x 18.01

                                 =6.977

                                  =6.98

Therefore, approximately 6.98 grams of water will be produced from 19 g of sulfuric acid.


Hope it helps!

Most chemical reactions involve the evolution or absorption of heat energy. True or False
sergejj [24]

Answer:

True

Explanation:

The majority of the reactions happened with a flow of heat. When there's no heat, the reaction is adiabatic.

For no adiabatic reactions, the heat can be released (evolution) by the system, so the reaction will be exothermic, or absorbed by the system (absorption), then the reaction is called endothermic.

Suppose 13L of gas is known to contain .965 Mol. If the amount of gas is Increased to 3.20 mol, what new volume will result? (Av
Ostrovityanka [42]

Answer &Explanation:

From Avogadro's lawa equal volume of gas contain equal number of moles

V=N

Hence

13L=965

XL=3.2mol

Hint:as the question state is increase to iteans final mol was 3.2 but if it could state by it would mean initial moles plus adde moles ie 3.2mol)

Cross multiplication

The new volume will be

=(3.2mol×13L÷965mol)

=0.043L
