<span>Endothermic Reaction. This reaction or process absorbs energy from its surroundings, mostly, but will not always be, in form of heat. A reaction that requires the input of energy that breaks a bond will always be endothermic. Best examples of endothermic reaction are: 1) melting cubes; 2) evaporating of liquid; 3) melting solid salts, etc.</span>
Most ionic compounds fall in the category of chemicals called salts. ... Electrolytes, or in other words compounds that are ionizable in solution, play an essential role in many body functions. Cells create electrical energy as ions move from the solutions inside the cells of our body<span> to the solutions outside the cells.
I hope my answer has come to your help. God bless and have a nice day ahead!

The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).
Answer:
Explanation:
5.81 x 10^-7 m x 10^-9nm/ 1m
=5.81 x 10^-16 nm
I don't actually know this is a guess and this is false
