The chemical and physical properties of chlorine. In ordinary conditions, chlorine is a yellow-green gas, with a density exceeding the density of air by 2.5 times. The melting temperature of chlorine in a solid state is -100.98 degrees Celsius, and its boiling point is -33.97 degrees Celsius.
Well if the candle lost half of its mass, and they are asking where the other half went. Most likely it is still hardened wax because the it says that you're candle lost half of its mass that means half is gone and the other half is still there. The chemical change would be liquid, and the chemical property would be Wax Vapour that is what i found.
-Hope it helps, if it does not help sorry.
Answer:
The total energy to break all the bonds in 1 mole of 1-propanol, C₃H₈O, is 4411 kJ/mol
Explanation:
We note that propanol, C₃H₈O is also known as 1-propanol is written as follows;
CH₃CH₂CH₂OH which gives
CH₃-CH₂-CH₂-OH
Hence, the total number of bonds are;
C-H Bonds = 3 + 2 + 2 = 7
C-O Bonds = 1
O-H Bond = 1
C-C Bonds = 2
The bond energies are as follows;
C-H Bonds = 413 kJ/mol
C-O Bonds = 358 kJ/mol
O-H Bond = 468 kJ/mol
C-C Bonds = 347 kJ/mol
Energy required to break the bonds in 1-propanol is therefore;
C-H Bonds = 413 kJ/mol × 7 = 2,891 kJ/mol
C-O Bonds = 358 kJ/mol × 1 = 358 kJ/mol
O-H Bond = 468 kJ/mol × 1 = 468 kJ/mol
C-C Bonds = 347 kJ/mol × 2 = 694 kJ/mol
The total energy to break all the bonds in 1 mole of 1-propanol = 4411 kJ/mol.
Answer:
N2 but i really didn't know
Answer : The molar volume of the gas will be, 44.82 L
Solution :
Using ideal gas equation,
where,
n = number of moles of gas = 1 mole
P = pressure of the gas = 0.5 atm
T = temperature of the gas = 273 K
R = gas constant = 0.0821 Latm/moleK
V = volume of the gas.
Now put all the given values in the above equation, we get the molar volume of the gas.
Therefore, the molar volume of the gas will be, 44.82 L
