An igneous rock that contains quartz and potassium feldspar would have a mineralogic content placing it in the range of ________
Ilia_Sergeevich [38]

Answer:

The answer is granitic or felsic rocks

Explanation:

Felsic is a term used in geology applied to silicate minerals, magmas and rocks, rich in light elements such as silicon, oxygen, aluminum, sodium and potassium (describs igneous rocks that are relatively rich in elements that form feldspar and quartz). This term is a combination of the words "feldspar" and "silica". Felsic minerals are generally light in color and have a specific gravity of less than 3. The most common felsic minerals are quartz, muscovite, alkaline feldspars (eg orthoclase) and feldspars from the plagioclase series. The most common felsic rock is granite. At the opposite end of the rock spectrum are mafic (rich in iron) and ultramafic (rich in magnesium) rocks and minerals.

The chemical compound SO₃ is planar in structure , the only intermolecular forces shown by SO₃ is the London forces .

dipole - dipole is not observed in this compound , as it is not possible to generate poles between the sulfur and oxygen atom due to very less difference in the electronegativity .

Hydrogen bonding is also not observed , because there is not hydrogen atom .

Hence , only London forces are observed in SO₃ .

soldi70 [24.7K]

During exercise , his body responds by an increase in the heart rate and his

respiratory rate.

<h3>What is Exercise?</h3>

Exercise refers to the activities which are done to improve the physical

fitness of an individual. Examples include:

  • Weight lifting
  • Running
  • Slipping etc.

The heart and respiratory rate are increased to ensure enough oxygen is

available to the cells of the body. This helps to ensure carbohydrate is

broken down to energy which is used by the body cells during the exercise

being performed.
