Answer:
Cobalt/Electron configuration
Explanation:
[Ar] 3d7 4s2
I really hope and think it’s E
Answer:
Na+
Explanation:
The equation would be:
HCl (aq) + NaOH (aq) --> HOH (l) + NaCl (aq)
The equation is already balanced and the NaCl will disassociate in Na+ and Cl- and HCl will disassociate into H+ and Cl- and NaOH will disassociate into Na+ and OH-. Na+ is on both sides of the equation and stays the same, so Na+ will be the spectator ion.
This layer also contains ratios of nitrogen and oxygen similar to the troposphere, except the concentrations are 1000 times less and there is little water vapor there, so the air is too thin for weather to occur. The thermosphere is the uppermost layer of the atmosphere.
Answer:
A quantum of electromagnetic energy is called photon
Explanation:
A photon corresponds to an elementary particle that composes the light, without any internal structure that is known at the moment. Said particle carries visible, ultraviolet, infrared, X-ray, gamma and other forms of electromagnetic radiation particles. The photon can travel in a vacuum at a constant speed and lacks mass or electric charge.
