Answer:
Mass of Fe produced = 44.7 g
Explanation:
Given data:
Mass of Fe produced in gram = ?
Mass of FeO react = 57 g
Solution:
Chemical equation:
2Al + 3FeO → 3Fe + Al₂O₃
Number of moles of FeO:
Number of moles = mass/ molar mass
Number of moles = 57 g/ 71.844 g/mol
Number of moles = 0.8 mol
Now we will compare the moles of Fe with FeO from balance chemical equation.
FeO : Fe
3 : 3
0.8 : 0.8
Mass of Fe:
Mass = Mass × molar mass
Mass = 0.8 mol × 55.845 g/mol
Mass = 44.7 g
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Answer: what is the relationship between protein and lipid metabolism?
On the short term increasing dietary protein in healthy subjects improved lipid metabolism, as seen by lower TG and IHL levels, but no glucose metabolism. On the long term ,however ,a high protein intake was related to a fatty liver, and associated to insulin resistance.

Answer:
Explanation:
<u>Molecular formula from Glucose:</u>
C₆H₁₂O₆
<u>3 moles of Glucose:</u>
3C₆H₁₂O₆
In 1 mole of Glucose, there are 12 hydrogen atoms.
<u>In 3 moles:</u>
= 12 × 3
= 36 H atoms

Answer:
Y > X > Z
Explanation:
The intermoecular forces refer to forces that exist between molecules of a substance. They are the secondary bond forces that hold particles of a substance together in a particular state of matter.
The shorter the distance between molecules, the greater the magnitude of intermolecular force between the molecules.
The molecules of Y are at the shortest distance from each other hence they have the highest magnitude of intermolecular forces. Followed by X and lastly Z with the greatest distance between the largest intermolecular distance.
