To write a balanced chemical equation for the standard formation reaction of liquid octanol form the octanol from its elements — C, H, and O.
The standard enthalpy of formation of a compound is the change in enthalpy when 1 mol of the compound is formed from its constituent elements. All substances must be in their most stable states at 100 kPa and 25 °C.
write a thermochemical equation for the formation of 1 mol of octanol.
8C(s) + 9H₂(g) + ½O₂(g) → C₈H₁₇OH(l)
To balance the nuclear reaction following rules are following:
1. The sum of the subscript means the atomic numbers must be equal on the both side of the equation.
2. The sum of the superscript means the mass numbers must be equal on the both side of the equation.
94 Pu 239 ------> x+ 2He4
The mass number:
239 = A+4
A= 235
The atomic number:
94 = Z+2
Z= 92
Thus the balanced nuclear reaction is as follows:
94 Pu 239 ------> 92U235+ 2He4
Answer:
mol times or devided by molar volume
