<span>The vaporization of br2 from liquid to gas state requires 7.4 k/cal /mol.</span>
I believe it’s A..but I’m not quite sure.
Answer:
C-12 or C with a 12 superscripted on Upper left and 6 Subscripted on bottom left
Explanation:
Isotopic notation
The heat absorbed by the water is
Q = 500 (4.18) (32.2 - 25)
Q = 15048 J
The enthalpy of fusion of the sodium acetate is:
<span>ΔHf = Q / m
</span><span>ΔHf = 15048 / 100
</span>ΔHf = 150.48 J/g
Answer:
The given isotope is Br 80
If 35 protons present then its atomic number is 35
Mass number is 80 so its meutrons are 45 because proton+ neutron = mass number
Its electron are 36 because of negative one charge
