There is currently no way to reliably predict when an earthquake will happen, its strength or length. Earthquakes can vary in their magnitude, the size of the earthquake at its source, and length, lasting from seconds to minutes.
Research has shown, that shaking of an earthquake displays a characteristic pattern. After the first tremors start, building up in intensity, a peak is reached, followed by a fading shaking. Large and small earthquakes start the same way, but there is no way to say when the peak, the maximal magnitude of the quake, is reached.
The answer is elements gain electrons. Oxidation reduction is elements lose electrons. And oxygen is added/lost can be a type of oxidation/reduction reaction.
Answer:
The answer to your question is pH = 9.5
Explanation:
Data
pOH = 4.5
pH = ?
pH measures the hydronium concentration [H₃O⁺]. The scale of pH goes form 0 to 14. If the solution has a pH from 0 to 6.9 the solution is an acid, if the pH = 7, the solution is neutral and if the pH goes from 7.1 to 14 the solution is an alkali,
Formula
pH + pOH = 14
-Solve for pH
pH = 14 - pOH
-Substitution
pH = 14 - 4.5
-Result
pH = 9.5
C
the number of protons is equal to the atomic number
Answer: Pt(Cl)2(NH3)2
Explanation:
In the formation of the complex, the oxidation number of platinum is plus two (+2) and two chloride ions cancel it out by their oxidation number of -1 each. Hence the complex has an overall charge of zero. It is thus neutral with no charge attached to its formula.
