Answer:

B.The use of piers and beams to build a strong foundation for a house

Explanation:

Foundation engineering falls under geotechnical engineering which uses both soil and rock mechanics to design the foundation structure of any building so as to avoid overloading of the soil. Foundation engineering is important to ensure stability and prevent lateral movement of the building.

Cancer research is done by cell biologist. Medical professionals help to cure sick people. Chemists study galvanic corrosion.

HELP ASAP WILL MARK BRAINLIEST: How many grams of aluminum can be extracted from 5000g of alumina
Lesechka [4]

The grams of aluminium extracted from 5000g of alumina is 2647 grams

<h3>Chemical formula of alumina:</h3>
  • Al₂O₃

Let's calculate the molecular mass of Al₂O₃

Al₂O₃ = 27 × 2 + 16 × 3 = 54 + 48 = 102 g/mol

Therefore,

102 g of Al₂O₃ = 54 g of aluminium  

5000g of Al₂O₃  = ?

mass of aluminium produced = 5000 × 54 / 102

mass of aluminium produced = 270000 / 102

mass of aluminium produced  = 2647.05882353

mass of aluminium produced  = 2647 grams

How many atoms of Fe are in 45.00 grams of Fe?
Licemer1 [7]

Answer:

4.852*10^23

Explanation:

Use dimensional analysis.

First turn grams to moles using the molar mass of Fe (you can't convert to atoms from grams).

Then turn moles into atoms using Avogadro's constant.

45g Fe/55.85 g/mol Fe*6.022*10^23 atoms Fe
