Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.
<h3>What are metals?</h3>
In engineering, metals are characterized to have electrical conductivity and other properties (e.g., ductility, reflectivity, etc).
For example, Lithium can be defined as soft metal (alkali metal) that is suitable to store electrical energy.
In conclusion, Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.

Answer:
I'm not sure if this right because i've only taken one year of Chemistry but the answer I got was
A. 24 g
Yes. Parts of a cell work together just like stations in a factory.
Answer:
Option C. 4.03 g
Explanation:
Firstly we analyse data.
12 % by mass, is a sort of concentration. It indicates that in 100 g of SOLUTION, we have 12 g of SOLUTE.
Density is the data that indicates grams of solution in volume of solution.
We need to determine, the volume of solution for the concentration
Density = mass / volume
1.05 g/mL = 100 g / volume
Volume = 100 g / 1.05 g/mL → 95.24 mL
Therefore our 12 g of solute are contained in 95.24 mL
Let's finish this by a rule of three.
95.24 mL contain 12 g of sucrose
Our sample of 32 mL may contain ( 32 . 12) / 95.24 = 4.03 g
