Answer:
The correct answer is A and D.
Explanation:
Please I want brainliest.
Reason:
The size of the ions follows the order:
Negatively charged ion > Neutral atom >
Positively charged ion
This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.
This happens due to the increase in 
electron-electron repulsion.
Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.
Thus the size of the positively charged ion is least.

Hi , if you are asking for the types of energy , here's your answer:
1. Radiative energy , because the microwave is releasing radiation.
2.Light energy , because there is light inside the microwave. 
3.electronic energy , because the microwave is using electricity.
        
             
        
        
        
Answer:
If the mass stays constant the object's density decreases as the volume increases. ... Because the property of density is a constant for all variables, density can be used to identify the material an object is made of.
Explanation:
 
        
             
        
        
        
0.24J/g*degC * 4.37g * 2.5degC = 2.622J
The 2.5 degC is the difference between 25 and 27.5 deg C.
