How many moles of Al2O3 will be formed when 27 grams of Al reacts completely with O2?

Chemistry
1 answer:
ruslelena [56]3 years ago
3 0

Explanation:

mole = mass in g/ molecular weight

molecular weight of Al2O3 =2(13) + 3(16) =74g/mol

reacting mass = 27 g

mole = 27/74 = 0.36mol

What are some examples of monomers and oligomers?
aleksandr82 [10.1K]
<span>What are some examples of monomers and oligomers?
</span>Organic molecules, such as proteins, carbohydrates, lipids and nucleic acids, are made of simple subunits called monomers. <span>Plasticizers are </span>oligomeric esters widely used to soften thermoplastics such as PVC and <span>urethane acrylate </span>. 
<span>
</span><span>If a chemical compound accelerates and regulates metabolic reactions, which type of role does it play - structural or physiological? 
</span>I believe the function that it plays would be physiological since it focuses more on the regulation of the reactions inside the body.

A 2.500g sample of compound containing only Carbon and Hydrogen is found containing 2.002g of Carbon. Determine the empirical fo
Dima020 [189]

The empirical formula : CH₃

<h3>Further explanation</h3>

Given

2.5 g sample

2.002 g Carbon

Required

The empirical formula

Solution

Mass of Hydrogen :

= 2.5 - 2.002

= 0.498

Mol ratio C : H :

C : 2.002/12 = 0.167

H : 0.498/1 = 0.498

Divide by 0.167 :

C : H = 1 : 3
