boiling point is the temp at which a liquid's vapor pressure equals the external pressure. At higher altitudes the external pressure is lower so vapor pressure becomes equal to external pressure at a lower temperature which is why boiling point decreases with increasing altitude.
I hope this helps you
Answer:
22.48 grams
Explanation:
Lets calculate the number of moles of CCl4 in 288.2 grams
Molar mass of CCl4 = 153.82 g/mol
mass % of carbon = 12 *100 / 153.82 = 7.8%
Hence, we can say that 7.8% of 288.2 grams is the mass of carbon
So, (7.8 * 288.2) / 100 = Mass of Carbon
Mass of carbon = 22.48 grams of carbon
The electronic configuration of a chlorine ion in BeCl2 compound is
[2.8.8]^- (answer B)
chlorine atom gain on electron form Be to form chloride ions
chlorine atom has a electronic configuration of 2.8.7 and it gains one electron to form chloride ion with 2.8.8 electronic configuration
Answer: If 
for a reaction equals zero, the reaction is at equilibrium.
Explanation:
When a thermodynamic closed system tends to do the maximum amount of non-expansion work then the energy used to do this work is called Gibb's free energy.
The expression for can be written as follows.
where,
= enthalpy change
T = temperature
= entropy change
This means that is the difference between heat released in a process and the amount of heat released in a reversible manner for the same process. So, when the value of of comes out to be equal to zero then it means no heat is released or absorbed.
Hence, the reaction is stable or at equilibrium.
Thus, we can conclude that the value of = 0 then it means that the reaction is at equilibrium.
