0.90g /cm^2
Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. To calculate for the density of the unknown metal, we simply divide the mass of the substance by the volume measured. We do as follows:
Density = mass / volume
Density = 222.50 g / 25 mL
Density = 8.9 g/mL
Answer:
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
Explanation:
The question ask to determine the longest wavelength of radiation that possesses the energy to break the bond and the minimum energy of 242kj/mol is required to break the chlorine-chlorine bond so the energy would be that the minimum wave length is 495nm and the high wavelength to it is the color green end of its wave
Answer:
Potential energy is at its highest when it is farthest in the air.
Kinetic energy is gretaest at the lowest point of movement.
