Answer: 3597 kJ of heat
Explanation:
According to ideal gas equation:
P = pressure of gas = 5.00 atm
V = Volume of gas = 8.00 L
n = number of moles = ?
R = gas constant =
T =temperature =
As it is given :
1 mole of propane produces = 2220 kJ of heat
Thus 1.63 moles of propane produces =
Thus 3597 kJ of heat is produced
Answer:
Explanation:
Hello!
In this case, since 12.75 g of calcium iodide has the following number of moles (molar mass = 293.89 g/mol):
In such a way, since 1 mole of calcium iodide contains 2 moles of atoms of iodine, and one mole of atoms of iodine contains 6.022x10²³ atoms (Avogadro's number), we compute the resulting atoms as shown below:
