What action leads to crystal formation in minerals?

Chemistry

I believe the correct answer from the choices listed above is option D. The action that leads to crystal formation in minerals is that  atoms or molecules form repeating patterns. Minerals are known to have a crystalline structure in which they exhibit short range and long range patterns.

<h3><u>Answer;</u></h3>

D. The atoms or molecules form repeating patterns.

<h3><u>Explanation;</u></h3>
  • <em><u>Minerals often take on specific geometric crystal shapes, such as a cube or other polygon. This is because they are formed with different combinations of atoms or molecules. Different arrangements of these atoms or molecules display different geometric crystal shapes.</u></em>
  • <em><u>The arrangement of these atoms and molecules in the structure of minerals depends on the type of atoms or molecules that make up the mineral.</u></em>
  • <em><u>Crystal structure is specific to each mineral, therefore examining the crystal structure is specific to each mineral.</u></em>

How can I do single replacement equations? For example, Silver metal immersed in potassium nitrate solution to yield. . .

Single replacement means only 1 will bond. Ag + KNO3 --> AgNO3 + K

Your lab partner named this compound 3-methyl-4-n-propylhexane, but that is not correct.

<u>Answer:</u> The correct IUPAC name of the alkane is 4-ethyl-3-methylheptane

<u>Explanation:</u>

The IUPAC nomenclature of alkanes are given as follows:

  • Select the longest possible carbon chain.
  • For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
  • A suffix '-ane' is added at the end of the name.
  • If two of more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.

We are given:

An alkane having chemical name as 3-methyl-4-n-propylhexane. This will not be the correct name of the alkane because the longest possible carbon chain has 7 Carbon atoms, not 6 carbon atoms

The image of the given alkane is shown in the image below.

Hence, the correct IUPAC name of the alkane is 4-ethyl-3-methylheptane

Energy of motion is referred to as CA. thermal energy B. electrical energy C. potential energy D. kinetic energy​
Natali [406]
It’s, D. Kinetic Energy.

Explanation: Energy associated with an object’s motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.

Hope this helped ;)
