Answer:
The water is universal solvent because it is a polar molecule.This have hydrogen bonding in which hydrogen molecule have positive charge and oxygen molecule have negative charge because electro negativity of oxygen molecule is higher than hydrogen molecule that is why it pull the hydrogen molecule and formed a polar molecule.That is why is also known as universal solvent.
Answer:
A. an observation
Explanation:
Because by saying that the leaf is green that is an observation on the leaf to tell what color it is.
Have a nice day/night :)
Answer:
The molecules of ammonia will effuse 1.28 times faster than carbon monoxide.
Explanation:
The kinetic molecular theory tells us that
Vrms = √(3RT/MW) where vrms is the root mean square velocity of an ideal gas
So vrms is inversely proportional to MW and so will be the rate of effusion. Comparing ammonia and co we have:
rate (NH3)/rate(CO) = √MWCO/√MWNH3 = √28.01/√17.03 = 1.28
rate(NH3) = 1.28 rate CO
Hey! So a strong acid would have a pH of about 0-3. So if it equals 2 it must be a strong acid.
Answer:
So she is very anxious because she has to wait 345600 seconds
Explanation:
60 second = 1 minute
60 minute = 1 hour
1 hour has 3600 seconds (60*60)
24 hour = 1 day
3600 second * 24 hours =
1 day has 86400 seconds so in four days
86400 * 4 = 345600
