Given reaction represents dissociation of bromine gas to form bromine atoms
Br2(g) ↔ 2Br(g)
The enthalpy of the above reaction is given as:
ΔH = ∑n(products)Δ
- ∑n(reactants)Δ
where n = number of moles
Δ
= enthalpy of formation
ΔH = [2*ΔH(Br(g)) - ΔH(Br2(g))] = 2*111.9 - 30.9 = 192.9 kJ/mol
Thus, enthalpy of dissociation is the bond energy of Br-Br = 192.9 kJ/mol
Hey there!:
Amount of purified acid phosphatase added to tube A = 5 ug ( micrograms )
Amount of acid phosphatase present in 400 ug of wheat germ extract in tube B :
1 / 100 = 5x / 400 =
100 x = ( 0.5 ) ( 400 ) =
x = (0.5 ) ( 400 ) = 100
x = 200 / 100
x = 2 ug
The amount of acid phosphatase present in 400 ug of the wheat germ in tube B is 2 ug
Hope that helps!
