Answer:
IUPAC name for Titin
Explanation:
The IUPAC name for Titin. This is the largest known protein and so has the longest chemical name. Written in full, it contains 189,819 letters.
Answer: See below
Explanation:
(i) 2AI + 3 NHANO3 → 3 N2+ 6 H2O + Al2O3 ΔH = -2030kJ
From stoichiometric coefiicients, it can be seen that:
When 2 moles of Al react, change in enthalpy = -2030kJ
So, when 3.4 moles of Al react, change in enthalpy = -(2030/2) x 3.4 kJ = -3451 kJ
Therefore, the change in enthalpy is -3451 kJ
(ii) The change in enthalpy is negative. This means heat is released during the reaction.
So the reaction is exothermic
