This will be highly depended on the case,
for example, when hydrogen attached to electromotive atom, we call it hydrogen bonding.
if the electrons in two atoms make them temporary dipole, we called it london dispersion forces, etc

The answer for the above question is the control. A control is that particular test that is done under standard conditions. Therefore, a controlled experiment is an experiment is where one test is done under standard or normal conditions, and all the other tests compare to the standard conditions. The standard conditions are majorly a temperature of 273 K or 0 degrees Celsius, and a pressure of 1 atm or 760 mmHg.
Answer:
Spontaneous at only low temperature. I made a chart for my AP Chem class if you want to refer to it.
Answer : The wavelength is 
Solution : Given,
frequency = 29.2 Hz
Formula used :
where,
= frequency
= wavelength
c = speed of light = 
Now put all the given values in this formula, we get the wavelength.
Therefore, the wavelength is
Answer:
[OH-] = 10^-4 M
Explanation:
pOH= 14- pH= 14-10=4
[OH-]= antilog (-4)= 10^-4M
