Answer:-
H+ + OH- --> H2O
Explanation:-
The chemical equation is NaOH + HNO3 --> NaNO3 + H2O
Now for the ionic compounds
HNO3 --> H+ + NO3 -
NaOH--> Na+ + OH-
NaNO3 --> Na+ + NO3-
Water being covalent will remain as H2O,
Hence
HNO3 + NaOH--> NaNO3 + H2O
H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.
Crossing out common terms
H+ + OH- --> H2O

and anion,
Explanation:
Naming of the ionic compounds:-
- The name of the cation is written first and the the name of the anion is written after the name of the cation separated by single space.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.
Hence, given ionic compound:-
is formed of cation,
and anion,
Thus, the name must be Cobalt(II) nitrate.

Answer:
Because as the concentration is diminished, the capacity to transfer electricity is diminished as well.
Explanation:
Hello!
In this case, since electrolytes are substances that are able to conduct the electricity in aqueous media (solutions in which water is the the solvent) because they have the capacity to form ions with both positive and negative charges, due to the fact that HCl is a strong acid, we notice it is fully ionized in solution and therefore it is a strong electrolyte. However, when the concentration is diminished, we can notice that strength is diminished as well because less ions will have the capacity to transfer the electricity and therefore it'd become a poor conductor or weak electrolyte.

What is the atomic number?
The total number of protons present in an atom is known as the atomic number of that atom. The atomic number has no correlation either with the number of neutrons or the number of electrons present inside an atom.
15N7 ⇒ 7 electrons, 8 neutrons, 7 protons
33S16 ⇒ 16 protons, 16 electrons, 17 neutrons
63Cu29 ⇒ 29 electrons, 34 neutrons,29 protons
84Sr38 ⇒ 38 electrons, 46 neutrons,38 protons
130Ba56 ⇒ 56 electrons, 74 neutrons,56 protons

Explanation:
Let's consider the following reaction.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
We can compute the pressures using an ICE chart.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
I 3.3 0.79 0
C -2x -x +2x
E 3.3-2x 0.79-x 2x
The partial pressure of sulfur trioxide gas is 0.47 atm. Then,
2x = 0.47
x = 0.24
The pressures at equilibrium are:
pSO₂ = 3.3-2x = 3.3-2(0.24) = 2.82 atm
pO₂ = 0.79-x = 0.79-0.24 = 0.55 atm
pSO₃ = 0.47 atm
The pressure equilibrium constant (Kp) is:
Kp = pSO₃² / pSO₂² × pO₂
Kp = 0.47² / 2.82² × 0.55
Kp = 0.051
