The Roman numerals in a cation's name indicate: THE POSITIVE CHARGE ON THE CATION
Cations are metallic atoms that loosely hold it electrons, making it easy to lose electrons.
The Roman numerals in a cation's name not only indicates the charge on the cation but it makes it easier to distinguish cations that share the same metal name.
Is this the full question?
<span>Heat that flows by conduction is the transfer of thermal energy between substances in contact. For this to happen, what must occur?
A) The two systems must be the same temperature.
B) The two systems must not be touching each another.
C) One system must have higher kinetic energy than the other system.
D) The thermal energy of one system must be the same as the thermal energy of the other system.</span>
Atomic mass is equal to the total number of electrons neutrons and protons
Answer:
the normality of the given solution is 0.0755 N
Explanation:
The computation of the normality of the given solution is shown below:
Here we have to realize the two sodiums ions per carbonate ion i.e.
N = 0.321g Na_2CO_3 × (1mol ÷ 105.99g)×(2eq ÷ 1mol)
= 0.1886eq ÷ 0.2500L
= 0.0755 N
Hence, the normality of the given solution is 0.0755 N
Lewis symbol for K+ is given by a dot and K.
<h3>Meaning of
Lewis symbol</h3>
Lewis symbols can be defined as a symbol the is used in describing the valence electron configurations of an atom ions.
A Lewis symbol consists of the symbol of the element and then surrounded by one dot for each of its valence electrons.
In conclusion, Lewis symbol for K+ is given by a dot and K.
