52.3 ug to g
one micro-gram is 10-6 gram
that is, 1 ug = 10-6 g
52.3 ug = 52.3 x 10-6 g
5.23 x 10-6 g = 5.23 x 10-5 g
The standard enthalpy change for the following reaction is - 52.3 kJ at 298 K. C2H4(g) — 2 C(s.graphite) + 2 H2(g) AH° = -52.3 kJ What is the standard enthalpy change for this reaction at 298 K? 2 C(s,graphite) + 2 H2(g) — C2H4(9) LLUCU The standard enthalpy change for the following reaction is -240 kJ at 298 K. Ni(s) + 1/2 O2(g) → Nio(s) AH° = -240 kJ What is the standard enthalpy change for the reaction at...
