Explanation:
Answer:
+125.4 KJmol-1
Explanation:
∆H C4H10(g) = -2877.6kJ/mol
∆H C(s)=-393.5kJ/mol
∆H H2(g) = -285.8
∆H reaction= ∆Hproducts - ∆H reactants
∆H reaction= (-2877.6kJ/mol) - [4(-393.5kJ/mol) +5(-285.8)]
∆H reaction= +125.4 KJmol-1
Explanation:
With all the scaling up and design improvements, the flight range of the R-7 increased to an intercontinental distance from 330 kilometers for the V-2. The R-7 ended up looking oversized even next to its American contemporaries -- the Atlas and Titan ballistic missiles.
