Noble gasses I think I could be wrong tho
B. Chemical energy to start a chemical reaction
Use blue litmus paper. This is an indicator that can safely determine whether it is a base or an acid by changing color in response to the substance. This color indicates whether it is an acid or a base. Refer to the pH scale to see if the substance is basic or acidic.
PV=nRT
Where:
P= pressure
V= volume
n= mol
R= universal gas constant
T= temperature
To get number of particles : apply the following equation.
n = N/L
Where ;
n =mol
N =number of particles
L =avagadro constant
Water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by Hydrogen bonds.
Hydrogen Bond
Between a hydrogen (H) atom that is covalently bonded to a more electronegative "donor" atom or group and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor—a hydrogen bond (or H-bond) forms (Ac). The second-row elements fluorine, oxygen, and nitrogen are the most common donor and acceptor atoms (F).
It may take place either intramolecularly or intermolecularly (between different molecules) (occurring among parts of the same molecule). The energy of a hydrogen bond can range from 1 to 40 kcal/mol and is influenced by the shape, surroundings, and nature of the particular donor and acceptor atoms.
