<u>Answer</u>:
"The earthquake shakes the position of land" is the most common way an earthquake changes Earth's land forms
<u>Explanation</u>:
Most of the times earthquake has been found to be making drastic reforms over the surface. With respect to the movement of ground other surface effects includes variation in the flow of groundwater, landslides and also in the direction flow change of mudflow. It affects the buildings, bridges, pipelines and railways and other important structures. the ground movement takes place due to the movement of underground rocks which found to be breaking near the faults. This release energy that further leads to movement of the tectonic plates. The generation of seismic wave from the energy.
Answer:
I don't know 100% but im pretty sure its electrons, if im wrong im really sorry let me know in the comments ill change it
explanation
the nucleus has more weight but its more compact but the electrons are spread apart circling the nucleus and therefor take up more space
D, Render aid and assistance. I learned this in my government/public administration class. If they don't they can be sued, and lose their job. It also slightly follows the 'Good Samaritan' law, but not fully.
<u>Given:</u>
Mass of Ag = 1.67 g
Mass of Cl = 2.21 g
Heat evolved = 1.96 kJ
<u>To determine:</u>
The enthalpy of formation of AgCl(s)
<u>Explanation:</u>
The reaction is:
2Ag(s) + Cl2(g) → 2AgCl(s)
Calculate the moles of Ag and Cl from the given masses
Atomic mass of Ag = 108 g/mol
# moles of Ag = 1.67/108 = 0.0155 moles
Atomic mass of Cl = 35 g/mol
# moles of Cl = 2.21/35 = 0.0631 moles
Since moles of Ag << moles of Cl, silver is the limiting reagent.
Based on reaction stoichiometry: # moles of AgCl formed = 0.0155 moles
Enthalpy of formation of AgCl = 1.96 kJ/0.0155 moles = 126.5 kJ/mol
Ans: Formation enthalpy = 126.5 kJ/mol
Answer:
a. participate in proton transfer - His
b. acts as a nucleophile - Ser
Explanation:
Enzymes are regulated because they are proteins. They are categorize based on how they catalyze. Heat weakens and inactivates the enzymes because of non covalent interaction. His amino acid participate in proton transfer because it is able to act as an acid as well as a base while Ser amino acid can act as nucleophile.
