Aluminum oxide produced : = 79.152 g

<h3>Further explanation</h3>

Given

46.5g of Al

165.37g of MnO

Required

Aluminum oxide produced

Solution

Reaction

2 Al (s) + 3 MnO (s) → 3 Mn (s) + Al₂O₃ (s)

  • mol Al(Ar = 27 g/mol) :

mol = mass : Ar

mol = 46.5 : 27

mol = 1.722

  • mol MnO(Ar=71 g/mol) :

mol = 165.37 : 71

mol = 2.329

mol : coefficient ratio Al : MnO = 1.722/2 : 2.329/3 = 0.861 : 0.776

MnO as a limiting reactant(smaller ratio)

So mol Al₂O₃ based on MnO as a limiting reactant

From equation , mol Al₂O₃ :

= 1/3 x mol MnO

= 1/3 x 2.329

= 0.776

Mass Al₂O₃ (MW=102 g/mol) :

= 0.776 x 102

= 79.152 g

In the first paragraph state how climate change is the earth warming. Tell them how the warmer atmosphere has lead to the melting of snow and ice in the arctic and sever droughts in other areas of the world.

In the second paragraph talk about how large rivers are becoming smaller in regards to water volume and that the amount of water discharged into the ocean has also decreased greatly.

In the final paragraph write about how weather phenomena impact global warming. State that El Niño has led to lower floods in some place whereas other areas have experienced an increase in floods. Finally tell the reader how the lower water volumes and discharge leads to a change in the global ocean circulation.

A method that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil is known as ______
Dimas [21]
The answer is indeed carbon dating, but let me explain it to you a little bit better: This is so because Carbon dating is the method that has the determination of the age of an organic matter. That is why we can say that that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil. Hope this clarifies everything

Why do canned baked beans last longer in a can than in air?
Alinara [238K]
Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.

Hope this sheds some light ♥︎
