First we start with our molecular equation to ensure all atoms are balanced in order to maintain the law of conservation of mass.

Hg_2(NO_3)_2_(_a_q_) + NaCl_(_a_q_) \implies Hg_2Cl_2_(_s_) + NaNO_3_(_a_q_).

The equation is unbalanced since we have 1 Cl atom on left hand side as opposed to 2 on the right hand side and we have 2 NO_3 molecules on left hand side and 1 on the right hand side. So we add a coefficient of 2 on  both the NaCl and NaNO_3

Hg_2(NO_3)_2_(_a_q_) + 2NaCl_(_a_q_) \implies Hg_2Cl_2_(_s_) + 2NaNO_3_(_a_q_)

The reaction occurs between solutes that are soluble in water to give a solid as a precipitate. So the complete ionic equation will show the soluble compounds in their dissociated states as ions in water and the insoluble compound as a solid.

2Hg^+_(_a_q_) + 2NO_3^-_(_a_q_) + 2Na^+_(_a_q_) + 2Cl^- _(_a_q_) \implies Hg_2Cl_2_(_s_) + 2Na^+_(_a_q_) + 2NO_3^-_(_a_q_)

What is an example of potential energy and kentic energy?
lana [24]
Potential energy is stored energy. Kinetic energy involves movement.

If a ball is on the top of a hill, it has the most potential energy on the very top of the hill. The kinetic energy is also 0 at this point.

If the ball rolls down the hill, potential energy decreases while kinetic increases.

2. 2. Consider the following reaction occurring in a closed chemical system. Assume that this reaction is at equilibrium and tha
Alika [10]

1. This is a combustion reaction.<span>

<span>Combustion reactions can happen with the </span>presence of O</span>₂ <span>gas. O₂<span> reacts with another element or compound and </span></span>oxidize<span> it. Here ethanol reacts with O₂<span> and produces </span></span>CO₂ and H₂O as products.<span> <span>Combustion is also called as </span></span>burning. <span>

2. Reaction will shift to right. <span>

</span><span>If more CH</span>₃CH₂OH is added to the system, then the</span> amount of CH₃CH₂OH will increase.<span> <span>Then the equilibrium in the system </span></span>will be broken.<span> <span>To make the equilibrium again, the </span></span>added CH₃CH₂OH should be removed.<span> To do that system will consume more CH</span>₃CH₂<span>OH to make products which helps to decrease the amount of ethanol. Hence, the reaction will shift to right.<span>

3. The reaction will shift to right.</span><span>

</span><span>If the water is extracted from the system, the </span>amount of water will decrease. <span>That means the </span>amount of products decrease. Then the system will try to gain equilibrium by increasing the water. To increase water the forward reaction should be enhanced. <span>Hence, the</span> reaction will shift to right.<span>

4. The reaction will shift to right.

</span><span>This is an </span>exothermic reaction <span>since it </span>produces heat. If the produced heat is removed, then the system will be cold. To maintain the temperature, system has to increase the amount of heat produced. Then, the forward reaction should be enhanced. Hence, the reaction will shift to right.<span>

5. The Le Chatelier's principle.

</span>Le Chatelier's principle says if a condition changes in a system which was in an equilibrium state, the system will try to gain equilibrium by correcting the changed condition back to normal. Most of industries which make chemicals use this principle</span>

The formation of iodine is described by the following chemical equation:
olga nikolaevna [1]

Answer:

N2O2(g) +O2(g) ===> 2NO2(g)

Explanation:

For a nonelementary reaction, the reaction equation is described as the sum of all the steps involved. All these steps constitute the reaction mechanism. Each step in the mechanism is an elementary reaction. The rate law of the overall reaction involves the rate determining step (slowest step) in the reaction sequence.

Now look at the overall reaction 2NO(g) + O2(g) ---------> 2NO2(g)

The two steps in the mechanism are

2NO(g) --------->N2O2(g) (fast)

N2O2(g) +O2(g) -------> 2NO2(g) (slow)

Summing all the steps and cancelling out the intermediate N2O2(g), we obtain the reaction equation;

2NO(g) + O2(g) ---------> 2NO2(g)

Hence the answer.
