Answer:
will be 90054 J
Explanation:
Number of moles = (mass)/(molar mass)
Molar mass of = 134.45 g/mol
So, 1.00 g of =
of
= 0.00744 mol of
0.00744 mol of produces 670 J of heat
So, 1 mol of produces
of heat or 90054 J of heat
Answer:
Explanation:
The given equation is:
Based on the reaction stoichiometry:
2 moles of barium chloride (BaCl2) reacts with 2 moles of sulfuric acid (H2SO4) to form 2 moles of barium sulfate (BaSO4) and 4 moles of HCl
Although the reaction is balanced, the correct convention is to depict reactions in terms of the lowest molar ratio. Therefore the coefficients (2,2,4 and 4) can be divided by 2 to give:
