Data Given:
[H⁺] = 3.16 × 10⁻⁷ M
To Find:
pH = ?
Solution:
As we know that,
pH = -log [H⁺]
Putting values,
pH = -log (3.16 × 10⁻⁷)
pH = 6.50
Kind of Solution:
As we know, when pH of a solution is equal to 7, it is Neutral. When less than 7, its Acidic and when greater than 7, it is Basic. As this solution has pH 6.50, which is less than 7, so it is slightly Acidic in Nature.
Earthquakes can cause massive distruction that can even cause death. In order to prevent any damage done to you, you must leave the scene immediatly, especially since an earthquake can tear down houses and buildings
Answer:
Mass stays the same but weight decreases due to a lack of gravity
Answer:
physical change
Explanation:
it doesnt change it chemically
<span>Observation is an important part of investigation.Small evidence may become the key factor for success. Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the recording of data via the use of instruments. The term may also refer to any data collected during the scientific activity.</span>
