With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.

Consider the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq). Which ions are spectator ions? pls

Marta_Voda [28]

Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$

<h3>What are spectator ions?</h3>

Ions that are not involved in the actual chemical reaction are called spectator ions.

A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.

Hence, Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$

Hurry. NO Spam! Write the neutralization reaction that occurs between HF and LiOH.

tekilochka [14]

Answer:

HF + LiOH = LiF + H2O.

Explanation:

Hydofluoric acid is a weak acid the solution would be slightly basic due to the following equilibrium (condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.)

Hope that helps. x
