Answer:
The cell's nucleus controls the activities of a cell and carries genes that contain information.
Density is equal to the mass divided by the voulme.
So: 2.5 multiplied by 2.5 by 2.5.
Then: 295 divided by 16.625=18.88g/cm to the power 3
To balance the chemical reaction above, we need to remember that the amount of the elements in the reactant side should be equal to the amount of that element in the product side. The balanced chemical reaction is written as:
<span>N2O5 +H2O --->2HNO3</span>
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.
