Answer:
0.66atm
Explanation:
Based on the reaction:
NH₄HS(s) ↔ NH₃(g) + H₂S(g)
The equilibrium constant, Kp, is defined as:
Kp = 0.11 = 
As moles of gas produced for NH₃(g) and H₂S(g) are the same, it is possible to write:
That means pressure of NH₃(g) is 0.33atm and H₂S(g) is, also, 0.33atm. Thus, total pressure is:
0.33atm×2 = <em>0.66atm</em>
Answer:
The factors on which the amount of energy absorbed by an endothermic reaction depends are the " physical state of the reactant and the difference in the potential energy of the reactant and the product".
Explanation:
In an endothermic reaction the factors that affects the reaction are the physical state of the reactant, which thus becomes the enthalpy. And the difference in potential energy of the reactant because if the sum of the potential energy is less than the sum of the potential energy of the product than the endothermic reaction will be positive and the reaction hence will be endothermic.

Answer:
(i) Oxidizing Agent: NO2 / Reducing Agent NH3-
(ii) Oxidizing Agent AgNO3 / Reducing Agent Zn
Explanation:
(i) 8NH3( g) + 6NO2( g) => 7N2( g) + 12H2O( l)
In this reaction, both two reactants contain nitrogen with a different oxidation number and produce only one product which contains nitrogen with a unique oxidation state. So, nitrogen is oxidized and reduced in the same reaction.
Nitrogen Undergoes a change in oxidation state from 4+ in NO2 to 0 in N2. It is reduced because it gains electrons (decrease its oxidation state). NO2 is the oxidizing agent (electron acceptor).
Nitrogen Changes from an oxidation state of 3- in NH3 to 0 in N2. It is oxidized because it loses electrons (increase its oxidation state). NH3 is the reducing agent (electron donor)
(ii) Zn(s) +AgNO3(aq) => Zn(NO3)2(aq) + Ag(s)
Ag changes oxidation state from 1+ to 0 in Ag(s).
Ag is reduced because it gains electrons and for this reason and AgNO3 is the oxidizing agent (electron acceptor)
Zn Changes from an oxidation state of 0 in Zn(s) to 2+ in Zn(NO3)2. It is oxidized and for this reason Zn is the reducing agent (electron donor).
Balanced equation:
Zn(s) +2AgNO3(aq) => Zn(NO3)2(aq) + 2Ag(s)
Scientists use tectonics plates to understand the plates moving beneath the volcano.
<h3>
What are tectonic plates?</h3>
According to the widely recognized scientific hypothesis known as plate tectonics, the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for nearly 3.4 billion years. Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust. Even now, every few hundred million years, it offers evolution a boost. The plates fit tightly against one another and sit on the heated, molten rock of the Earth's mantle like fragments of a broken shell. The plates move as a result of the heat produced by nuclear processes occurring inside the planet.
