Answer:
C) 2 H2(g) + O2 (g) 2 H2O (l) AH° = -571.6
kJ/mol
Explanation:
The magnitude of heat released in an exothermic reaction is shown by the magnitude of the change in enthalpy.
The more negative the enthalpy change of the reaction, the more the heat released by the process.
Hence, 2 H2(g) + O2 (g) 2 H2O (l) AH° = -571.6
kJ/mol has the most negative value of enthalpy change hence the greatest amount of heat is released in this reaction.
Answer:
Volume required = 0.327 L
Explanation:
Given data:
Volume in L = ?
Molarity of solution = 1.772 M
Mass of BaCl₂ = 123 g
Solution:
First of all we will calculate the number of moles of BaCl₂,
Number of moles = mass/molar mass
Number of moles = 123 g/ 208.23 g/mol
Number of moles = 0.58 mol
Now, given problem will solve by using molarity formula.
Molarity = number of moles / volume in L
1.772 M = 0.58 mol / Volume in L
Volume in L = 0.58 mol / 1.772 M
Volume in L = 0.327 L
it is 6,6-Dibromoheptan-2-ol
