In this experiment you will determine the density of an unknown liquid. You will measure the mass of a known volume delivered from a pipet and use the expression:
<span><span><span>M
V</span></span><span>D=</span><span /></span>
where D = density, M = mass and V = volume to calculate the density of the unknown liquid.
A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons<span> instead of the usual two. The most common double bond, that is between two </span>carbon atoms<span>, can be found in </span>alkenes<span>. Many types of double bonds exist between two different elements.</span>
Explanation:
Ph=14-4.23
Ph=9.77
Its a Base because bases have high Ph and acids have low ph
