There are 5 atoms 1=LI 1=N 3=O
<span>The best response would be that theories are not opinions. While laws and theories are similar, laws tend to be a collection of theories about the same phenomenon. Laws can be expressed as math formulae, but more often they're in the form of "if-then" statements. Laws and theories both have to be rigorously tested before they reach these classiffications.</span>
The correct answer is 19.72 °C. The first step is to determine the amount of heat that was lost per gram (30,000 J) / (390 g) = 76.92 J/g. Then to determine the temperature change, divide 76.92 J/g with the given specific heat of milk (76.92 J/g) / (3.9 J/g°C) = 19.72 °C.
The object's mass is around 69.592 kg
F=mg
Option B & Option D is your correct answers.
'cause here, atom has eight electrons in it's valence shell, so it means it has stable structure which falls in group 18
Hope this helps!
