Answer:
The amount of C2H4I2 produced is maximized if
-Adding C2H4 to the reaction mixture
-Decreasing the reaction volume
-Also can include: raising the reaction temperature
Answer: 873 kJ of energy will be required to break two moles of hydrogen gas.
Above chemical equation shows that two moles of hydrogen gas is reacting with one mole of oxygen gas to give two mole of water molecule.
Bond energy of H-H = 436kJ
According to reaction we have two moles hydrogen,so energy required to break the
H-H bond in two moles of hydrogen gas will be:
= 872kJ
872kJ of energy will be required to break H-H bond in two moles of hydrogen gas.
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
Answer: 1.21 moles to 3 sig figs
Explanation:
All gases occupy 22.4 liters per mole of gas at STP.
(22.4 L/mole) at STP is an imoportant conversion factor. It helps to remember it and is good cocktail party conversation, for the right crowd.
(27.2L CO2 gas)/(22.4 L/mole) = 1.21 moles to 3 sig figs
