Answer:
The correct answer is option B) "Higher-magnitude earthquakes do not always happen deeper in Earth's crust".
Explanation:
The table shows data of magnitude and depth of earthquakes that occurred at different time and at different locations. By analyzing the data we can conclude that higher-magnitude earthquakes do not always happen deeper in Earth's crust. At first glance we can thought that higher-magnitude earthquakes occur at high depth. However, the earthquake of Michoacan have a higher-magnitude than the earthquake of Alexandria (8 and 6.3, respectively), and the earthquake of Michoacan occurred at 12 miles of depth, while the earthquake of Alexandria occurred at 15 miles of depth.

Answer:
HCl solution - H30+ and Cl ions. pH 3
NaCl - Na+ and Cl-. pH 7
Explanation:
a) HCl solution - the hydrogen ion combines with water molecule to form the hydronium molecule which is responsible for acidity. The chloride ion is also found in solution.
pH = -log [H+] = -log(10^-3) = 3
b) NaCl 10-3 g. The solid dissocates in water forming the Na+ and Cl- ions. None of these ions affect pH
So the equation is balanced, meaning they have the smallest amounts of each element in the reactants to create the products.
So, 2 moles of H2S (the coefficient) contributes to 2 moles Ag2S, which is why the ratio is 2:2.
I hope that made sense.
