The balanced overall ionic equation for leads (ii) nitrate dissolving in water:

Pb (NO₃) ₂ (s) → Pb²⁺ (aq) + 2NO₃⁻ (aq)

<h3>Further explanation </h3>

The electrolyte in the solution produces ions.

The equation of a chemical reaction can be expressed in the equation of the ions

For strong electrolytes (the ionization rate = 1) is written in the form of separate ions, while the weak electrolyte (degree of ionization <1) is still written as an un-ionized molecule

In the ion equation, there is an ion spectator that is the ion which does not react because it is present before and after the reaction

When these ions are removed, the ionic equation is called the net ionic equation

For gases and solids including water (H₂O) can be written as an ionized molecule

So only the dissolved compound is ionized ((expressed in symbol aq)

Ionic compounds consist of cations (ions +) and anions (ions -)

Lead (ii) nitrate, Pb (NO₃) ₂ is a solution (ion compound) which, if dissolved in water, ionizes into Pb2 + cation and NO3- anion

Pb (NO₃) ₂ (s) → Pb²⁺ (aq) + 2NO₃⁻ (aq)

Missing question: <span>What will happen if we combine the solution of sodium iodide and the solution of lead(II) nitrate?
Chemical reaction 1: Pb(NO</span>₃)₂(s) → Pb²⁺(aq) + 2NO₃⁻(aq).
Chemical reaction 2: 2NaI(aq) + Pb(NO₃)₂(aq) → PbI₂(s) + 2NaNO₃(aq).
Ionic reaction:
2Na⁺(aq) + 2I⁻(aq) + Pb²⁺(aq) + 2NO₃⁻(aq) → PbI₂(s) + 2Na⁺(aq) + 2NO₃⁻(aq).
Net ionic reaction: 2I⁻(aq) + Pb²⁺(aq) → PbI₂(s).

What mass of nitrous oxide can be formed from 48.7 g of nitrogen?

Arisa [49]

$\\ \tt\bull\rightarrowtail2 N_2+O_2\longrightarrow 2N_2O$

2mol of N_2 forms 2mol of N_2O
1mol of N_2 forms 1mol of N_2O

Moles of N_2

$\\ \tt\bull\rightarrowtail \dfrac{48.7}{14}=3.4mol$

Molar mass of N_2O=44g/mol

Mass of N_2O formed

44(3.4)=132.16g

Suppose you have a 0.10 M solution of AlBr3. What is the concentration of each ion? A. 0.10 M Al3+ ions and 0.30 M Br- ions B. 0

podryga [215]

<u>Answer:</u> The concentration of $Al^{3+}$ ions is 0.10 M and that of $Br^-$ ions is 0.30 M

<u>Explanation:</u>

We are given:

Concentration of $AlBr_3$ = 0.10 M

The chemical equation for the ionization of aluminium bromide follows:

$AlBr_3\rightarrow Al^{3+}+3Br^-$

1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions

So, concentration of aluminium ions = 0.10 M

Concentration of bromide ions = $[(3\times 0.1)]=0.3M$

Hence, the concentration of $Al^{3+}$ ions is 0.10 M and that of $Br^-$ ions is 0.30 M

Arrange the following gases in order of decreasing density at STP. Ne, O2, F2, Cl3

kipiarov [429]

Answer: Cl₃ > F₂ > O₂ > Ne

Explanation:

1) All the gases are at the same temperature and pressure: STP (O°, 1 atm).

2) All the gases are represented by one molecule (or mole of molecules, it is the same for our puroposes).

3) As per Avogadro's law and the ideal gas equation, the same number of particles (of any gas) occupy the same volume at the same temperature and pressure.

For example, at STP the volume of 1 mol of gas is 22.4 liter.

4) Since, density is equal to mass / volume, and you assume the same number of molecules of each gas, the order of the densities is the same that the order of the molar masses.

5) Then, you just need to state the molar mass of each gas and order in decreasing order of molar mass to have the correct order for density.

6) Molar masses:

i) Ne: 20.180 g/mol

ii) O₂: 2× 15.999 g/mol = 31.998 g/mol

iii) F₂: 2×18.998 g/mol = 37.996 g/mol

iv) Cl₃: 3×35.453 g/mol = 106.359

7) Then the order is: 106.359 > 37.996 > 31.998 > 20.18 ⇒ is Cl₃ > F₂ > O₂ > Ne.

Note: the values calculate are not of densities but of molar masses. The order is what is the same.
