When Hg2Cl2 reacts with NH3 and it undergoes the redox reaction and it forms the following products and here Hg in liquid state and HgNH2Cl is in solid state and then Nh4Cl is in aqueous form so the net ionic equation is as follows:

What is redox reaction?

Redox reactions consist of two halves, a reduced half and an oxidized half, and always occur simultaneously. The reduced half gains electrons and decreases its oxidation number, and the oxidized half loses electrons and increases its oxidation number. An easy way to remember this is a mnemonic device called OIL RIG. This means "oxidation is loss" and "reduction is gain". In a redox reaction, there is no net change in the number of electrons. What is released in the oxidation half-reaction is incorporated into another species in the reduction half-reaction.

Two species that exchange electrons in a redox reaction have special names. An ion or molecule that donates

electrons is called a reducing agent. It reduces other species by donating electrons.

So what is oxidized is the reducing agent and what is reduced is the oxidizing agent.

the theoretical yield of the reaction is 70.97%

Calculation :

Initially, 6CO₂ +H₂O ---> C₆H₁₂O₆ +6o₂

18.6 moles  2.38*10² g

since , mole = weight / molar wt

(mole )H₂O = 2.38*10² /18 = 13.2

6 moles of CO₂ reacts with 6 moles of H₂O .

so, 13.2 moles of H₂O will react with 13.2 moles of CO₂

produced C₆H₁₂O₆ = 13.2/6 = 2.20 mole

remaining CO₂ = 18.6 - 13.2 = 5.4

generally theoretical yield is 100%

here , moles of C₆H₁₂O₆ should be produced = 18.6/6 = 3.1

so the Theoretical yield = (2.2/3.1)*100 = 70.37 %

Real-world chemical reactions don't always go as planned on paper. During the course of an experiment, many things contribute to the production of less product than expected.In addition to spills and other experimental errors, losses often occur due to incomplete reactions and unwanted side reactions.

To calculate the yield, you need to determine the amount of product produced based on stoichiometry. This is called the theoretical yield and is the maximum amount of product that can be formed from a given amount of reactants.

Answer:

Below

Explanation:

The Celcius scale is defined by water's boiling and freezing points

  boils at 100° C   and freezes at 0 ° C

     at MINUS 74 ° C  it would be frozen...SOLID

At -74 degrees Celsius, water would be in a solid state, specifically as ice.

Water undergoes a phase transition from liquid to solid at its freezing point, which occurs at 0 degrees Celsius (32 degrees Fahrenheit) under normal atmospheric pressure. As the temperature drops below the freezing point, the water molecules lose energy, and their movement slows down. Eventually, the attractive forces between the water molecules become stronger than the kinetic energy they possess, leading to the formation of a regular crystalline structure.

At -74 degrees Celsius, the temperature is significantly below the freezing point of water, so the water molecules have lost a considerable amount of energy. As a result, the water molecules slow down even further, and the intermolecular forces hold them tightly in place, forming a solid state known as ice.

Ice is characterized by a specific arrangement of water molecules in a crystal lattice structure. It is less dense than liquid water, which is why ice floats on top of water bodies. At -74 degrees Celsius, water exists as a solid ice, and its molecular movement is limited to small vibrations within the rigid structure of the ice lattice.
