Sodium Chloride is placed in water, what happens to the sodium ions and chloride ions in the solution.

Answers

Answer 1
Answer: Na+ ion in sodium chloride is attracted to the oxygen side of the water molecules, while the Cl- ion is attracted to the hydrogens' side of the water molecule

this causes the sodium chloride to split in water, and the sodium chloride dissolves into separate Na+ and Cl- atoms

Aquatic organisms in lakes and ponds are often able to survive the water underneath a layer of ice because the water underneath the ice remains liquid. Which property of water is primarily responsible for creating these favorable conditions for aquatic life?

Answers

Answer:

The property is that water expands when it freezes and oxygen is trapped inside

Explanation:

Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. The oxygen is present in water under the ice and this oxygen is used for breathing by the marine and aquatic animals.

Describe at least three of the possible functions of proteins, and explain how proteins can be so diverse when there are only a limited number of different amino acids.

Answers

an answer might be - Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

In a vacuum, the gravitational force is "turned off." (2 points)Select one:
True
False

Answers

The given statement is false.  

• In a vacuum, when an object falls it is subjected to only one kind of force, that is, the gravitational force, which is considered as the object's weight.  

• In a vacuum, all the objects fall at the same rate due to gravitational force. In a vacuum, the mass of the object does not matter.  

• In a vacuum, the moving of the object only takes place due to gravity is considered to be free-falling, and its motion is illustrated by Newton's second law of motion.  

Thus, gravitational force does exist in a vacuum.

Answer: False

Explanation: Because, A vacuum has no particles of gas in it, but there is still gravity it just has nothing to act upon.

Philisophically, it is much like the tree falling in the woods with no one there to hear it. That is to say the gravity only exists if it can be perceived by one of the senses.
