Indeed they are. The uranium atoms have separate numbers of neutrons in their nuclei, but still have the same number of protons.
Answer:
Explanation:
Given
Initial Form: Onyx
Final Form: Rectangular Solid
Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm
Required
Volume of the solid (in cm³)
The volume of a solid is calculated as thus;
Assume the following;
The first thing to do is to convert the assumed height from mm to cm
Given that;
This implies that
Hence, the dimension of the solid in cm is:
The Volume is then calculated as;
Hence, the volume of the rectangular solid is
Im pretty sure it is a, but i may be wrong
The chemical formula for this compound would be V2O5.
