Calculate the formula unit mass of CaCl2​

Chemistry
1 answer:
melomori [17]3 years ago
3 0
Formula unit mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the empirical formula of a compound. It is expressed in amu.

Atomic mass of calcium = 40 amu

Atomic mass of chlorine = 35.5 amu

Formula mass of CaCl2 = (1 x 40) + (2 x 35.5) = 111amu.

What is the difference between electronegativity and ionization energy
Katena32 [7]

Answer:

These properties are basically the inverse of each other.

Explanation:

  • Electronegativity is the tendency of an atom to attract an electron and make it a part of its orbital.

        Ionization enthalpy, is the energy required to remove an electron from                        an atom.

  • More electronegative atoms have high ionization enthalpies If the energy required to remove an electron is less, i.e. the atom has more tendency to give electron, it would thus have less tendency to take electron.
  • Values and tendency of electronegativity in the periodic table: In general, the electronegativity of a non‐metal is  larger than that of metal. For the elements of one period the electronegativities increase from  left to right across the periodic table. For the elements of one main group the electronegativities  decrease from top to bottom across the periodic table. To the subgroup elements, there’s no  regular rule.
  • Values and tendency of ionization potential in the periodic table: The first ionization energy is the energy which is  required when a gaseous atom/ion loses an electron to form a gaseous +1 valence ion. The  energy which is required for a gaseous +1 valence ion to loose an electron to form a gaseous +2  valence ion, is called the second ionization energy of an element.  In general, the second ionization energy is higher than the first ionization energy of an element. The first ionization energies of the elements of one period increase from the left to the right  across the periodic table. According to the elements of main group, the first ionization energies  generally decreases from top to bottom across the periodic table.

a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.

Explanation:

A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.

A wave is a disturbance that transmits energy from one place to another.

There are two major types of waves:

  • Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
  • A wave in string going up and down is a transverse wave.
  • Electromagnetic waves are transverse waves.
  • Seismic s-waves are transverse waves.
  • Sound waves are longitudinal waves propagated parallel to their source.
