Ans :
CO2 is a gas and CH3OH is a liquid at room temperature since greater energy is required to vaporise the compound.
CO2 is a non polar molecule due to equal dipole moments in opposite directions so no strong intermolecular forces.
CH3OH is an alcohol that has strong hydrogen intermolecular bonding in between its particles.
So CO2 vaporises easily at room temperature making it a gas whereas CH3OH is unable to vaporise at room temperature and hence liquid.
at room temperture, CO2 is in its gas form, while CH3OH is in its liquid form....
Explain the following observations: (a) CO2 is a gas but H2O is a liquid at room temperature (b) H2O is a liquid at room temperature but NH3 and HF are gases (c) H2O and Br2 are liquids at room temperature but I2 is a solid (d) CH4 is a gas at room temperature but C5H12 is a liquid
explain on a molecular level why liquid co2 has lower entropy than gas co2
CUI 110 Oxygen, O2, and methanol, CH3OH, have the same mass: 32 amu. Explain why oxygen is a gas at om temperature, while methanol is a liquid at room temperature. 3 Why is the boiling point of ammonia higher than the boiling point 4 What type of interaction is responsible for sodium chloride's very high melting point? 5. What type of interaction is responsible for water's high boiling point?
Explain why Carbon Dioxide is a gas at room temperature while a diamond is a solid even though they both have covalent bonds.
2. 1.487 g of methanol (CH3OH, a liquid at room temperature) is completely combusted at 25 °C in a bomb calorimeter with a heat capacity of 10.22 kJ/°C. The final temperature is found to be 28.291 °C. a. Calculate the standard heat of combustion of CH2OH(D) (ACH ) in kJ/mol at 25 °C. b. Calculate the standard heat of formation of CH3OH() (AFH ) in kJ/mol at 25 °C.
explain why elemental chlorine (Cl2) is a gas at room tempeature and pressure while iodine (I2) is a solid despite the fact that both have similar lewis structures. explain based on the relative strength of their intermolecular forced of attraction.
The conversion of solid CO2 ("dry ice") to CO2 gas is product-favored at room temperature. What would be the signs for ΔG, ΔH, and ΔS at room temperature? CO2(s) --> CO2(g) ΔG = (+) ΔH = (+) ΔS = (-) ΔG = (-) ΔH = (+) ΔS = (-) ΔG = (+) ΔH = (+) ΔS = (+) ΔG = (-) ΔH = (+) ΔS = (+) ΔG = (-) ΔH = (-) ΔS = (+)
