I would see chemical constitution and physical components are not changed.
Because physical reaction won't change the component itself
Answer:
See explanation and images attached
Explanation:
There are two compounds that could have molecular formula of C2H6O, they are ethanol and methoxy methane (trivial name: methyl ether). The structures of the two compounds are shown in the image attached as obtained from quora.
The boiling point of methoxymethane is -24.8°C while that of ethanol is about 78.5°C. The reason for the high boiling point of ethanol is the presence of intermolecular hydrogen bonding leading to a stronger intermolecular interaction compared to methoxymethane molecules held together only by very weak dispersion forces.
If you hit something it hurts in an equal amount that you hurt it
Answer:
4 m/s
Explanation:
This because 8/2 = 4 so it is 4m/s
The unknown alcohol = 2-propanol
<h3>Further explanation</h3>
Given
volume = 50 ml
mass = 39.4 g
Required
The unknown alcohol
Solution
Density of sample :
= mass : volume
= 39.4 g : 50 ml
= 0.788 g/ml
The unknown alcohol at room temperature = liquid, so the unknown alcohol is 2-propanol because it has temperature range between -90 to 82 for liquid and the density = 0.788 g/ml
