At decomposition of solid substance with formation of gas leads to increase in an entropy. For example,
60°C
NH₄NO₂(s) = N₂(g) + 2H₂O(l)
true
Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!

Answer:
Selenium has 36 valence electrons.
The answer to this question should be Carbon dioxide.
To count the molar mass you need to add all the atoms weight that made up the compound. Carbon dioxide or CO2 is made of one carbon and two oxygen. Carbon molecular weight is 12. Oxygen molecular weight is 16. Then if you add them you will got: 12+ 2*16= 12 +32 = 44 g/mole.
