The electron arrangement of the outer energy level of an atom determines whether or not it will form chemical bonds. Or The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond.
The first thing to do is to calculate the new concentration of the solution after dilution. We do as follows:
M1V1 = M2V2
(3.0 M).006 L = M2 (18 L)
M2 = 0.001 M HNO3
When in solution it dissociated into ions as follows:
HNO3 = H+ + NO3-
[H+] = 0.001 M HNO3 ( 1 mol H+ / 1 mol HNO3 ) = 0.001 M H+
pH = -log[H+] = -log 0.001 = 3
An occluded front forms when a warm air mass is caught between two cooler air masses. The warm air mass is cut ofl or occluded' from the ground. The occluded warm front may cause clouds and precipitation. A swirling center of low air pressure is called a cyclone.
PH is what they call measure of the concentration<span> of hydrogen ions in a solution. Strong </span>acids <span>like hydrochloric </span>acid<span> at the sort of </span>concentrations<span> you normally use in the lab have a pH around 0 to 1. The lower the pH, the higher the </span>concentration<span> of hydrogen ions in the solution. </span>
