Answer:
D. The equipment needed to accommodate the high temperature and pressure will be expensive to produce.
Explanation:
Hello!
In this case, for the considered reaction, it is clear it is an exothermic reaction because it produces energy; and therefore, the higher the temperature the more reactants are yielded as the reverse reaction is favored. Moreover, since the effect of pressure is verified as favoring the side with fewer moles; in this case the products side (2 moles of ammonia).
In such a way, the high pressure favors the formation of ammonia whereas the high temperature the formation of hydrogen and nitrogen and therefore, option A is ruled out. Since the high pressure shifts the reaction rightwards and the high temperature leftwards, we would not be able to know whether the reaction has ended or not because it will be a "go and come back" process, that is why B is also discarded. Now, since hydrogen and nitrogen would be the "wastes", we discard C because they are not toxic. That is why the most accurate answer would be D. because it is actually true that such equipment is quite expensive.
Best regards!
Germanium (Ge) is an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). As it has an atomic mass greater than that of sulfur (S), but less than that of cadmium (Cd).
<h3>Why does the element of the same group have similar chemical behavior?</h3>
The chemical behavior of elements depends on the number of valence electrons in their outermost shell. Elements placed in the same group have the same number of valence electrons. Therefore, elements placed in the same group of the periodic table have similar chemical properties.
The elements having a similar outer electronic configuration in their atoms are arranged in the same group of the periodic table. These valence electrons are responsible chemical properties and reactivities of the elements.
Therefore, silicon and lead can be replaced by any element belonging to the same group in which Si and Pb are present. So we have germanium and tin. But germanium is the element that has an atomic mass greater than sulfur (S), but less than cadmium (Cd).

Answer : The correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
Explanation :
Electrochemical cell : It is a type of device which is used to convert the chemical energy into electrical energy during the redox reaction.
In the electrochemical cell, there are two electrodes. The electrode on which the oxidation takes place is called the anode (or negative pole) and the electrode on which the reduction takes place is called the cathode (or positive pole). This cell is connected by the salt bridge.
In the external circuit, the electrons flow from the anode (negative pole) to cathode (positive pole) through the voltmeter.
In the inner circuit, the ions flow through the salt bridge.
Hence, the correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
2 and 3 because a neutron is neutral, a proton is positive, and a electron is negative. So they both have 0 and 1. (neutron and proton or electron)
