We want:
S(s) + O2(g) --> SO2(g)
So the following are the given:
1) S(s) + 3/2O2(g) --> SO3(g) ∆H = -395.8 kJ/mole
2) 2SO2 + O2 --> 2SO3(g) ∆H = -198.2 kJ/mole
Reverse Equation 2) and then divide by 2
SO3(g) --> SO2(s) + 1/2O2(g) ∆H = +99.1 kJ/mole
Add Equation 1)
S(s) + O2(g) --> SO2(g) ∆H = -296.7 kJ/mole
Chemical reactions happen when two or more atoms go together to form molecules or when Atoms brake
Answer:
Potassium iodide
Explanation:
The white solid introduced into the solution is potassium bromide. This is an ionic solid thus it quickly dissolves in water to yield a colorless solution.
When chlorine is added to this solution, the iodine is displaced since chlorine is above iodine in the electrochemical series.
When mixed with hexane, the color of the solution changes to purple.
Answer:
km/h
mph
iph
Explanation:
I have no idea what mis or dit could be
km/h is kilometers per hour
mph is miles per hour
I assume iph is inches per hour?
Answer: 143.3
137+115+104+263+98 divided by 5.Which gives us 143.3
