Answer:
3 fluorine atoms will be present
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
Since protons are postive and neutrons are neutral. Then it is postive.
Answer: D
Explanation: As temperature increases, the solubility of a solid or liquid can increase or decrease depending on whether the dissolution reaction is exothermic or endothermic. In endothermic reactions, the net energy from the bonds breaking and forming results in heat energy being absorbed when the solute dissolves in solution.
