Molar mass is the mass of Avogadro's number of atoms of that element or compound. Avogadro's number is 6.02 x 1023 and can be used to represent the number of representative particles of any particle on the atomic scale. The molar masses of the elements are listed on the periodic table....
Methane, CH4, is acovalent compoundwith exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carbon (C) linking or bonding ...
The boiling point of an element or compound is the set temperature at which it will transition from a liquid state to a gaseous state. The boiling point is always higher than the melting point, which is the temperature at which the substance transitions from a solid to a liquid....
In leaded petrol there is an additive composed of lead, carbon and hydrogen only. This compound contains 29.7 % carbon and 6.19 % hydrogen by mass. What is the value of ''x'' in the empirical formula PbC_8H_x? Is CH4 an empirical formula?
Phospholipids are the main component of the cell, or plasma, membrane. The cell membrane is important because it creates a thin, flexible barrier between the cell and the environment that is semi-permeable, only allowing certain molecules in and out....

IgM is a multivalent antibody which evolved as a first line defense of adaptive immunity. It consists of heavy and light chains assembled into a complex oligomer. In mouse serum there are two forms of IgM, a full-length and a truncated one. The latter co
