Answer:
I think it is mixture and of chemical reaction
Answer:
The answer to your question is: the third option is correct.
Explanation:
"Alkenes" ________.
are reasonably soluble in water This option is incorrect, alkenes are insoluble in water.
are relatively polar compounds This option is wrong, alkenes are not polar molecules.
have lower boiling points than alcohols of similar molecular weight This option is true, alkenes have a lower boiling point than alcohols.
both have lower boiling points than alcohols of similar molecular weight and are relatively polar compounds. This option is incorrect because is combining true with false facts.
Answer: 6.6 ml
Explanation:
If you had a 0.200 L solution containing 0.0140 M of Fe3+(aq), and you wished to add enough 1.27 M NaOH(aq) to precipitate all of the metal, what is the minimum amount of the NaOH(aq) solution you would need to add? Assume that the NaOH(aq) solution is the only source of OH−(aq) for the precipitation.
You have 0.014X0,2 = 0,0028 moles of Fe ion.
You need 0,0028 X 3 = 00084 moles of OH
The NaOH is 1.27 moles/liter
0.084/1.27 = 6.6 ml
Answer:
For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.
Answer:
36.3
Explanation:
The full answer would be 36.3426, but because of the 0.21, you round it down to 3 sig figs.
