Molecular chemical equation: 
K₂C₂O₄(aq)+Pb(OH)₂(aq) → 2KOH(aq) + PbC₂O₄<span>(s).
Ionic equation:
2K</span>⁺(aq) + C₂O₄²⁻(aq) + Pb²⁺(aq) + 2OH⁻(aq) → 2K⁺(aq) +2OH⁻(aq)+PbC₂O₄(s)
Net ionic eqation:
C₂O₄²⁻(aq) + Pb²⁺(aq) → PbC₂O₄(s).
s is solid, do not dissolve in water, potassiom hydroxide is trong base and dissolves in water.

For the of freezing liquid ethanol at a given temperature and pressure,A. ΔH is positive and ΔS is positive.B. ΔH is positive an
Ksivusya [100]

Answer:

ΔH is negative and ΔS is negative.

Explanation:

Endothermic reaction -

The type of reaction in which energy is absorbed in the form of heat is known as endothermic reaction .

The reaction mixture usually get cooled after the reaction .( temperature decreases ) .

The sign of ΔH of an Endothermic  reaction is positive .

<u>For the of process of freezing the liquid ethanol  ,  energy in the form of heat is released and hence , exothermic reaction ΔH is negative  .</u>

<u>In the process of freezing , liquid is converted to solid , i.e. , the randomness reduces , and hence , entropy also decreases , hence , ΔS is negative .</u>

How do cells respond to contact with other cells?
Blababa [14]
It depends on the function and activity of both cells. Most normal cells crease division if they came into contact with other cells however the immune system interact directly with pathogens or foreign organisms to destroy them.

What volume of chlorine gas measured at StP will be liberated by a current of 2.5 A flowing for a period of 1.8 hours through an
Oliga [24]

The volume of chlorine gas measured at STP will be liberated by a current of 2.5  A flowing for a period of 1.8 hours through an aqueous solution of AgCl is 1.88 litre.

<h3>What is Faraday's law ?</h3>

According to Faraday's Law , During Electrolysis , The amount of substance liberated at the cathode or anode is directly proportional to the electricity that is passed through the cell.

The reaction taking place at anode is:

2Cl → Cl₂ +2e −

The total charge is calculated as

Q=I×t= 2.5×1.8×60×60 coulomb

Q = 16200 coulomb

The amount of chlorine liberated by passing 16200 coulomb of electric charge

= 16200/(2*96500)

= 0.084 mole

Volume of Cl₂ at STP is

​1 mole at STP has 22.4 L of Gas

0.084 mole of Cl₂ at STP will be equal to 22.4 *0.084 = 1.88 litre of Cl₂
