Answer:
To calculate electronegativy, find the electronegative values of each element involved in the bond. Once you know those values, subtract the higher from the lower to determine the electronegative difference.
Explanation:
Obtain an electronegativity value chart
Every element on the periodic table has a set electronegativity; these charts are easily obtainable through the Internet or a general chemistry textbook. Electronegativity is the ability of an element to attract electrons towards itself.
Determine the electronegativity of the individual elements in the bond
Using the table obtained in step one, find the electronegative value of each element. On the periodic table, electronegativity increases from left to right along a period and decreases as you go down a group.
Determine the electronegative difference between the two elements
Subtract the smaller electronegative value obtained from the larger electronegative value. This positive value is the electronegative difference for the bond. A larger electronegative difference represents a polar bond in which the sharing of electrons is unequal.
Use the electronegative difference to determine the type of bond
The closer the electronegative difference is to zero, the less polar a bond is. An electronegative difference of zero represents a nonpolar bond. A value between zero and two represents a polar covalent bond. A value greater than two represents an ionic bond. Fluorine is the most electronegative element, with an electronegativity of 4.0.
A pion is an unstable particle that has an average lifetime of 26.033 nanoseconds (2.6033×10−8 seconds). This is the time interval between its creation in a nuclear process and its extinction into decay.
a pion (or a pi meson, denoted with the Greek letter pi: π) is any of three subatomic particles: π0, π+, and π−. Each pion consists of a quark and an antiquark and is therefore a meson. Pion are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions π+ and π− decaying after a mean lifetime of 26.033 nanoseconds (2.6033×10−8 seconds),
The fundamental reason for merging space and time into spacetime is that space and time are separately not invariant, which is to say that, under the proper conditions, different observers will disagree on the length of time between two events (because of time dilation) or the distance between the two events (because of length contraction). But special relativity provides a new invariant, called the spacetime interval, which combines distances in space and in time. All observers who measure the time and distance between any two events will end up computing the same spacetime interval.

Answer:
c. 0.30
Explanation:
One C atom has a mass of 12.0 u and one Ar atom has a mass of 40.0 u.
Let’s assume that there are <em>n</em> atoms of C and <em>n</em> atoms of Ar. Then
Mass of <em>n</em> C atoms = <em>n</em> × 12.0
Mass of <em>n</em> C atoms = 12.0<em>n</em> u
Mass of <em>n</em> Ar atoms = <em>n</em> × 40.0
Mass of <em>n</em> Ar atoms = 40.0<em>n</em> u
ratio = mass of C/mass of Ar
ratio = 12.0<em>n</em>/40.0<em>n
</em>
ratio = 0.300
