An unsaturated hydrocarbon with a double bond is called an alkene. hope i helped.
:)
Heat released : 79086 J
<h3>Further explanation</h3>
Condenses :
1. phase change (gas - liquid) : heat of vaporization (ΔH vap for water = 2260 J/g)
2. cools from 100 - 10 : (Q=m.cΔT)
1. Q=m.ΔH vap
2. Q=mc.ΔT(c water = 4.18 J/g C)
Q tot = 67800 + 11286 = 79086 J
Note that we are omitting the water.
So, sodium carbonate will basically dissociate into positive sodium ions and negative carbonate ions based on the following equation:
<span>Na2CO3 → 2 Na(+) + CO3(2-)
</span>
If we took water into consideration:
Sodium carbonate will dissociate in water forming carbonic acid and sodium hydroxide. Since sodium hydroxide is a strong base, therefore, it will then neutralize the gastric acid, thus, acting as an antacid.
