<u>Answer:</u> The spectator ions are $CN^-\text{ and }Li^+$

<u>Explanation:</u>

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$H^++CN^-+Li^++OH^-\rightarrow Li^++CN^-+H_2O$

The ions which are present on both the sides of the equation are lithium and cynaide ions.

Hence, the correct answer are $CN^-\text{ and }Li^+$

Imagine an emission spectrum produced by a container of hydrogen gas. Changing the gas in the container from hydrogen to helium

irinina [24]

Answer: A) True

Explanation: The difference in energy levels in an atom is responsible for the emission of photons. Emitted photons have different energies because energy levels are discrete. The energy of a photon gives information about its frequency and subsequently, its colour.

As the two gases (Hydrogen & Helium) are distinctively different gases with different discrete energy levels in their atoms, it is logical that the frequency and colour of the emitted photons from their respective atoms would be different.

In the correct lewis structure for the nitrate ion, no3 –, nitrogen has how many covalent bonds?

Colt1911 [192]

Answer : The correct Lewis-dot structure of nitrate ion is shown below and the nitrogen has 4 covalent bonds.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The number of valance electrons are shown by 'dot'.

The given molecule is, nitrate ion

As we know that nitrogen has '5' valence electrons and oxygen has '6' valence electron.

Therefore, the total number of valence electrons in $NO_3^-$ = 5 + 3(6) + 1 = 24 electrons

According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.

The correct Lewis-dot structure of nitrate ion is shown below.
