F and O
because they are more reactive than Cl
Strongest reducing agents are in Group 1 . For example lithium. The strongest oxidising agents are in Group 7 , For example Fluorine.
I'm pretty sure its the weight of the book
Answer : The partial pressure of X and Y gases are, 0.525 and 1.575 atm respectively.
Explanation : Given,
Moles of X = 2.0 mole
Moles of Y = 6.0 mole
Total pressure = 2.1 atm
Now we have to calculate the mole fraction of X and Y.
and,
Now we have to calculate the partial pressure of X and Y.
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas = 2.1 atm
= mole fraction of gas
and,
Thus, the partial pressure of X and Y gases are, 0.525 and 1.575 atm respectively.
CHEMICAL ENERGY
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.
Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, food, gasoline, and oxygen gas.
