Answer: A photon of energy was released.
Explanation: The energy of the orbitals keep on increasing as the size of the orbitals keep on increasing or the value of n keeps on increasing.
The electrons absorb energy when they are irradiated or put at high temperatures and move to higher energy states. The electrons then get back to their ground state by releasing energy in the form of radiations. Thus when an electron move from n = 2 to shell n = 1, the absorbed energy is given off in form of photons of energy.
Energy is released or absorbed in the form of discrete packets of energy called as photons.
Answer:
D
Explanation:
Al is a reducing agent because it removes Oxygen from another compound
Mno2 is an oxidizing agent
Your answer should be 4.002602!!!
Answer:
Explanation:
The difference is in the amount of heat required to increase their temperature by 1 °C
It takes 4.19 joules to increase the temperature of water by 1 °C compared to Aluminium which is 0.900 joules to raise the temperature by 1 °C. Consequently, Aluminum will cool easily compare to water which will retain some of it heat longer because it does not heat up quickly like Aluminum.
Answer: C. 1000 Newton
Explanation:
Given that :
Weight of moon rover on earth = 6000 newton
Approximate of moon rover on moon will be?
Weight of an object (W) = mass(m) × acceleration due to gravity(g)
To get the mass of moon rover(m) :
m = weight / acceleration due to gravity
g on earth = 9.8m/s²
Hence,
mass of moon rover = 6000/ 9.8
= 612.244kg
Surface gravity on the moon is about 1.6m/s²
Hence ;
Weight of moon rover on the moon :
Mass of moon rover × 1.6m/s²
= 612.244 × 1.6m/s²
= 979.59 Newton
= 1000 Newton (nearest thousand)
