11Alexandr11 [23.1K]

Answer:

<u>Balanced equation:</u>

Pb(NO_{3})_{2}(aq)+K_{2}CO_{3}(aq)\rightarrow PbCO_{3}(s)+2KNO_{3}(aq)

Explanation:

The chemical reaction between Lead(II) Nitrate and potassium carbonate is as follows.

Lead(II)Nitrate+Potassium\,carbonate \rightarrow Lead(III)\,\,carbonate+Potassium\,nitrate

Pb(NO_{3})_{2}(aq)+K_{2}CO_{3}(aq)\rightarrow PbCO_{3}(s)+2KNO_{3}(aq)

<u>Ionic equation:</u>

Pb^{2+}(aq)+2NO_{3}^{-}(aq)+2K^{+}(aq)+CO_{3}^{2-}(aq)\Leftrightarrow PbCO_{3}(s)+K^{+}(aq)+2NO_{3}^{-}

Cancel the same ions on the both sides of the reaction.

The net ionic equation is as follows.

Pb^{2+}(aq)+CO_{3}^{2-}(aq)\Leftrightarrow PbCO_{3}(s)

Chemical substances that dissolve in water or react with water to release ions are known as
disa [49]
The answer is electrolytes. Strong electrolytes like strong acids, strong bases and salts dissociate completely into ions when dissolved and no neutral molecules are present in their solution. Weak electrolytes like weak acids and weak bases do not completely ionize in water and some neutral molecules are present in their solution, while nonelectrolytes do not dissociate into ions when in solution at all.

gizmo_the_mogwai [7]

Yes: with help from different machinery, the heavy metals can be discovered and can be used to build stronger products and create further positive solutions to life


No: Economically, the advances toward creating heavy metals are frowned upon. We could disrupt the physical features of the metals and cause a chemical reaction.

A sample of oxygen that occupies 1.00 * 10^6 at 575 mm Hg is subjected to a pressure of 1.25 atm. What will the final volume of
Vlada [557]

A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.

<h3>What does Boyle's law state?</h3>

Boyle's law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

  • Step 1: Convert the initial pressure to atm.

We will use the conversion factor 1 atm = 760 mmHg.

575 mmHg × 1 atm/760 mmHg = 0.757 atm

  • Step 2: Calculate the final volume of the gas

A sample of oxygen occupies 1.00 × 10⁶ mL (V₁) at 0.757 atm (P₁).

If the pressure is increased to 1.25 atm (P₂), we can calculate the new volume (V₂) using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁ / P₂

V₂ = 0.757 atm × 1.00 × 10⁶ mL / 1.25 atm = 6.06 × 10⁵ mL

A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.
