Obliviously not all rocks have holes in them
It is called vesicular texture These refers to viscles holes pores or cavities within the igneous rock.the vesicles are the result of gas expansion(bubbles).which often occur during volcanic eruptions .
Answer:
pH = 2.56
Explanation:
The Henderson-Hasselbalch equation relates the pH to the Ka and ratio of the conjugate acid-base pair as follows:
pH = pKa + log([A⁻]/[HA]) = -log(Ka) + log([A⁻]/[HA])
Substituting in the value gives:
pH = -log(1.77 x 10⁻⁴) + log((0.0065M) / (0.10M))
pH = 2.56
It is because, due to high electronegativity, it easily accepts electron; and form a stable bond with solution......
When you see or visit grasslands you know that :
- They have mild to hot summers ( B )
- They have a lot of precipitation ( A )
<h3><u>Grassland vegetation</u> </h3>
Grasslands are a type of vegetation found mostly in areas with favourable weather conditions such as mild summers and right amount of precipitation which provides the grasslands with enough water for proper growth.
Other types of vegetation include :
- Forest vegetation
- Tundra and
- Desert vegetation
Desert vegetation expreciences very hot summers and little precipitation which leads to the scarcity of green vegetation, while forest vegetation expreciences a very high level of precipitation.
Hence we can conclude that When you see or visit grasslands you know that :They have mild to hot summers ,They have a lot of precipitation
