Answer:
C
Explanation:
Exothermic means that heat is released from the reaction
The advantage of using an orbital notation is that it shows the electron distribution in shells.
<span>Dot structures only show the valence electrons of an atom which are the electrons found at the outermost shell. The orbital notation gives a more detailed depiction of the electrons in each shell. This is most advantageous for atoms that have special cases. </span>
<span>Some examples of atoms that have special electronic configurations are copper and chromium. For example, copper is more stable when the 3d subshell is completely filled. This leaves the 4s subshell with only 1 electron. Chromium is also more stable when its s and d subshells are only half full. The orbital notation depicts these special cases, whereas the dot structure does not.</span>
I don’t know about 1 But number 2 is AB + xH2O = AB.xH2O
Answer:
67200 centimeters hope this helps :)
It should be 13.48%.
1130g NaCL/7250g Ice + 1130 NaCl=0.1348 x 100%= 13.48%
