A rock _____ can get polished from water running over it?

Chemistry

Musya8 [376]3 years ago

Answer:

The answer is: B

Explanation:

The reason for this is because when a rock is underwater (the river, in this case), the water runs across it non-stop until the rock is removed from the water. The only way it can be polished if it is submerged under the water for quite some time (years and years).

I hope this helped! :))

Answer:

The answer is B.  A river is a body of water, therefore, there will always be some water running over the rock.

Explain how a metal and a non-metal form an ION when they chemically react together.
Marizza181 [45]

Answer:

When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound. In all of these reactions, the metal atoms give electrons to the non-metal atoms.

13. Base your answer to the following question on the information below and on your knowledge of chemistry.
ahrayia [7]

From our knowledge of periodic trends, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.

<h3>Periodic trends</h3>

The periodic trends are those properties that increase or decrease down the group or across the period. These periodic trends include;

  • Ionization energy
  • Electron affinity
  • Atomic radius
  • Ionic radius etc

As more shell are added down the group in group 14, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
