Lauren has a big social studies test coming up. She knows that she needs to spread out her study sessions over a period of time.
tatuchka [14]

The study strategy Lauren is using in spreading her study sessions over a period of time is pacing, which helps the student develop a schedule focused on their own study pace.

<h3>Pacing Study Sessions</h3>

This study strategy of distributing the study into short sessions rather than studying the entire content through one long session is more effective in retaining content and learning.

What happens is that Lauren is using mass repetition processing, which can be compared to a longitudinal wave in physics, with spaces in between, concentrating the initial review close to the proof to ensure retention and avoid forgetting.

Through pacing, Lauren achieves greater motivation to carry out her studies in a concentrated and focused way, helping her to retain and preserve knowledge.

The correct answer is:

  • Pacing

What’s the name of the organic molecule
Delvig [45]

Answer:

hexane

Explanation:

This is a 6- carbon hydrocarbon with no multiple bonds or any functional groups (such as -OH). Thus, the prefix 'hex' refers to the 6 carbons and 'ane' refers to the molecule being an alkane.

Naming molecules:

<u>Number of </u><u>carbons</u>

• pentane: 5 carbons

• hexane: 6 carbons

• heptane: 7 carbons

• octane: 8 carbons

• nonane: 9 carbons

<u>Functional </u><u>groups</u> (for 6- carbons molecules)

• Alkene (C=C): hexene

• Alcohol (-OH): hexanol

• Alkyne (C≡C): hexyne

In which of the following is the number of electrons the ion contains given correctly
larisa [96]

Answer:

B. K+ has 18 electrons

Explanation:

  • Ions are formed when atoms of element gain or loose electrons.
  • <em><u>When an atom looses electrons it forms a positively charged ion and when an atom gains electrons it forms a negatively charged ion.</u></em>
  • Metal atoms such as potassium, magnesium and aluminium looses outer most electrons to positively charged ions.
  • <u>Potassium atom has 19 electrons, 19 protons, with an electronic configuration of 2 : 8 : 8 : 1.</u> <u><em>To form an ion, K looses an electron to form a positively charged potassium ion (K+) with 18 electrons and 19 protons and an electronic configuration of 2:8:8.</em></u>
