Answer:
n = 4 there are 16 orbitals
Potential energy (PEI due to gravity = mgh
Where, m= mass of the billboard, g=gravitational acceleration (9.81 m/s^2), h = height
Therefore,
m= PE/(gh) = 175000/(9.81*30) = 594.63 kg
Answer:Thermal energy transfer involves the transfer of internal energy.
Explanation:
Three types of thermal energy transfer are conduction, convection and radiation.
As the temperature of the system increases, the energy of the system also increases, speeding the system up.
Explanation:
Magnesium is more reactive then chromium. So, when magnesium hydroxide reacts with chromium (lll) iodide then magnesium displaces chromium.
When magnesium hydroxide and chromium (lll) iodide are mixed together then it results in the formation of magnesium iodide and chromium hydroxide.
The chemical reaction equation is as follows.
