1245 liters because you move the decimal place over to the right six times
The energy change if 84.0 g of CaO react with excess water is 98KJ of heat is released.
calculation
heat = number of moles x delta H
delta H = - 65.2 Kj/mol
first find the number of moles of CaO reacted
moles = mass/molar mass
the molar mass of CaO = 40 + 16= 56 g/mol
mass = 84 g
moles therefore = 84 g/56 g/mol =1.5 moles
Heat is therefore = 1.5 moles x -65.2 = - 97.8 Kj = -98 Kj
since sign is negative the energy is released
Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun.
