I would radiation a robotics arm but for a heated surphace is Shiny surfaces are poor absorbers and emitters (but they are good reflectors of infrared radiation).
Using the formula Density = Mass / Volume,
Mass = Density x Volume
Mass = 2.75 x 8 = 22g
<span>Ionic compounds are normally in which physical state at room temperature in solid. The answer is A.
</span>Ionic Compounds Are Balanced. Table salt is an example of an ionic compound.
