Answer:
150
Explanation:
A gas will have the lowest rate of diffusion the lowest temperature from a given set of temperature values.
Since 150 is the lowest value, then this represents the lowest rate of diffusion.
The rate of diffusion is related to the prevalent temperature. When gases diffuse, they move from regions of high concentration to the at of low concentration. They must have enough kinetic energy to move in order to diffuse.
The higher the temperature, the more the kinetic energy and higher rate of diffusion.
Answer:
butanal
Explanation:
It's not 1-propanone because otherwise you have OH bonded to C not O and H bonded to C separately. 2-butanol means that the O and H would be bonded to a different C atom, and it's not propyl hydrogen ether because the O would be in the chain of bonded Cs.
Hope this helps :)
Answer:
Substance A is a Giant covalent structure with covalent bonding
Explanation:
Substance A is a Giant covalent structure. There are strong covalent bonds between the atoms and a large amount of heat energy is needed to break the bonds resulting in high melting point. Substance A does not conduct electricity in molten state reason being, it exist as molecules which are electrically neutral and there are no mobile charged carriers.
Hope this helps!
