Weathering<span> breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are </span>two types<span> of </span>weathering<span>: </span>mechanical<span> and </span>chemical<span>. </span>Mechanical weathering<span> is the disintegration of rock into smaller and smaller fragments.</span>
When Kw = [H+] [OH-]
when Kw is the ion-product constant for water = 1 x 10^-14
and [H+] is the hydrogen concentration (which we need to calculate)
and [OH-] = 0.65 M
so by substitution:
1 x 10^-14 = [H+] * 0.65
∴[H+] = 1.54 x 10^-14 m
Answer:
The Substance Has Changed and Has Become Something Else
Explanation:
When a chemical reaction occurs it has a few characteristics, for example burning. The substance, paper, becomes something else, ash. The ash can no longer be turned back into paper. Another example is rust, once and object is rust due to oxidation it can no longer return back. A physical reaction on the other hand can be reversed, like freezing. <u>To spot chemical change</u> look for color changing, gas production, a change in temperature, or if you see any light.
