It would be lithium and Chlorine because they are trying to get 8 valence electrons and 1 valence electron plus 7 valence electrons.
The purpose of this process is to make sure that the substance is completely melted before trying to figure up the mass. if there are still bits of solid in the liquid the mass will be incorrect if just taken the first time. Also, some substances have gaseous elements in them so to heat it up, it releases those gases and you’re left with the true mass in the liquid.
hope this helps!
I think its the 3rd one 0.21
Answer:
I think they both need water and sun light to stay alive
Explanation: Animals need water so they can have energy and they have extra energy when they are in the sun they have more energy
<span>(3) C4H8</span>
C=12, H=1
CH2= 12+2=14
(CH2)n=56g/mol
14n=56
n=4
(CH2)4=C4H8
