Answer:
It depends. what hot spot are you looking for?
I think it’s an ionic compound? An example is salt because water breaks it up due to the polar bonds.
NaCl = [Na+] + [Cl-]
Those conduct electricity.
Explanation:
The given molecule is
H3C - C ≡ C - CH3
The numbering order is shown below:
H3C - C ≡ C - CH3
1 2 3 4
So, the alkyne group is in the second position.
The carbon chain has four carbons.
Hence, the IUPAC name of the given compound is:
2-butyne.
Answer:
It would be thermal energy.
Explanation:
Thermal energy is the energy transfer of heat which is created while doing physical activity.
1.the chemical change color from colorless to purple
2. A yellow gas forms
3.a brown solid forms in the bottom of the beaker
4.the temperature of the chemicals rises 15 Celsius
Explanation:
All of the options are proofs that chemical change has occurred.
A chemical change is one with the following properties:
- A new kind of matter is usually formed as seen by the gas evolution and the formation of the insoluble precipitate i.e brown solid at the bottom of the beaker.
- They are not easily reversible.
- Usually accompanied by energy changes as seen in the rise in temperature.
- Color changes can also infer chemical changes in a reaction.
