Compare the patterns of earthquakes, volcanoes, and mountain ranges on earth?
At diverging plate boundaries, earthquakes occurs as the plates pull away from each other. Volcanoes form between the plates, as magma rises upward from the underlying mantle. Second, two plates may come together, at a converging plate boundary. Two situations are possible at converging plate boundaries.
Mountain ranges, volcanoes, and earthquakes can all be found when convergent borders occur. Finally, transform boundary locations are also the site of earthquakes. Every learning exercise we completed served as a piece of proof.
What is earthquakes ?When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.
Earthquakes often result from subsurface rock breaking unexpectedly and fast movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
A fault line causes the Earth's crust to suddenly shift, causing an earthquake. The epicenter is the place where an earthquake first occurs. Near the epicenter of an earthquake, shaking may be quite violent.
Thus, mountain ranges, volcanoes, and earthquakes can all be found when convergent borders occur.

consider the following intermediate reactions. the overall chemical reaction is as follows. what is the correct enthalpy diagram using the hess law for this system
The question is incomplete, here is the complete question:
Consider the following intermediate reactions.
[tex]CH_4(g)+2O_2\rightarrow CO_2(g)+2H_2O(g);\Delta H_1=-802kJ[/tex]
The overall chemical reaction is as follows:
[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(I);\Delta H_{rxn}=-890kJ[/tex]
What is the correct enthalpy diagram using the Hess law for this system? (Image is attached below)
Answer: The correct image is Image A.
Explanation:
According to Hess’s law of constant heat summation, the amount of heat absorbed or evolved in a given chemical equation or system remains the same whether the process occurs in one step or in several steps.
According to this law, the enthalpies of these chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to know the required equation.
It also means that the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The given intermediate reactions are:
[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l);\Delta H_1=-802kJ[/tex] ...(1)
[tex]2H_2O(g)\rightarrow 2H_2O(l);\Delta H_2=-88kJ[/tex] ....(2)
The final reaction follows:
[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l);\Delta H_{rxn}=-890kJ[/tex]
Negative sign of the enthalpy represents the heat is being released which is represented by the downward arrow in the diagram.
By adding equation 1 and equation 2, we get:
[tex]\Delta H_{rxn}=\Delta H_1+\Delta H_2\\\\\Delta H_{rxn}=-802+(-88)=-890kJ[/tex]
Hence, the correct image is image A.

The density of water at 4 degrees Celsius is 1.000 g/mg is it chemical or physical property?
Answer:
Physical Property
Explanation:
Density, mass, volume, color, melting and boiling points, etc. are all physical properties. No matter what changes, the chemical makeup stays the same.
Flamability, acidity, toxicity, etc. are chemical properties, because they chemically change the makeup of the object/thing.
