<em>hey, im jordan :)</em>
the SI unit for the mass of subatomic particles is <u>amu (atomic mass unit)</u>
<em>hope this helps!</em>
<em>have a great day :D</em>
GaBr3
Gallium=Ga
Bromine= Br
Bromide=Br3
Answer :
The steps involved in the electron dot structure of
are :
First we have to determine the total number of valence electron in
.
Number of valence electrons in N = 5
The charge on N is (-3). So, we add 3 electrons.
Total number of valence electrons = 5 + 3 = 8 electrons
The image is shown below.
It is endothermic reaction ΔH>0 (sign is +).
Because it is spontaneous reaction ΔG<span><0 (Gibbs free energy)
</span>ΔG=ΔH-TΔS, so must be TΔS>ΔH and ΔS<span>>0 (sign +).</span>
