Air has a lower heat capacity which is the property of a material that describes how much heat energy is required to change the temperature of a substance by one degree Celsius <span />
Hello!
The approximate bond angle around the central carbon atom in acrolein is
120°
The structure of acrolein is shown in the figure below. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).
Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°.
Have a nice day!
When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
Answer:
Add 10 mL of ethanol into a 100 mL volumetric flask. Final volume of diluted ethanol solution is 100 mL.
Explanation:
We need to use a flask of 100 mL to make a 10 times dilution of the 10 mL of ethanol that we have. To prepare this solution we have to measure with a pipet 10 mL of ethanol and place it into volumetric flask of 100 mL. Then we add destiled water to complete the volume of the final ethanol solution.
Then the final volume of the diluted solution of ethanol will be 100 mL.
