Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
Answer:A
Explanation:
Your muscular system is at work
Answer:
See explanation
Explanation:
The word equation is just a statement of the reaction in words as follows;
Magnesium oxide ----> Magnesium metal + oxygen gas
An unbalanced stoichiometric equation doesn't have equal number of atoms of each element on both sides.
Hence the unbalanced stoichiometric equation is as follows;
MgO(s) -----> Mg(s) + O2(g)
pH of solution = 9.661
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
pOH=-log[OH⁻]
![\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339](https://tex.z-dn.net/?f=%5Ctt%20pOH%3D-log%5B4.583%5Ctimes%2010%5E%7B-5%7D%5D%5C%5C%5C%5CpOH%3D5-log~4.583%3D4.339)
pH+pOH=pKw
Answer:
B
Explanation:
The Niels Bohr's atomic model superior to all the earlier models is because it showed how the electron could orbit the nucleus without falling into it
