Question 1 of 20

Which statement describes the difference between covalent bonds and Van

der Waals forces?

O A. Covalent bonds form from the attraction of positive ions and

freely moving electrons, while Van der Waals forces cause an

attraction between nonpolar molecules.

B. Covalent bonds form when there is an attraction between

nonpolar molecules, while Van der Waals forces cause two atoms

to share valence electrons.

C. Covalent bonds occur when two atoms share valence electrons,

while Van der Waals forces cause an attraction between positive

Answers

Answer 1

Answer:

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

Answer 2

Answer:

Covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.

Explanation:

Apex.

What are some examples of lab saftey rules. Explain why these rules are put in place for the learning environment and what would a lab class look like without any lab safety rules.​

Answers

Answer:

How was the government able to make children go to residential school?

help me out bro!!! !! ! !

Examples of lab safety rules:
- wearing protective and proper clothing (eg. goggles, gloves, close-toed shoes)
-locating emergency equipment (eg. eyewash station, fire extinguisher, fire blanket)
- not eating or drinking liquids
- handling chemicals properly and following lab procedures
- dispose waste properly and clean up area when finished.
-do not consume any chemicals or substances
- be attentive
There’s a lot more but these are the most common ones.


—————-
These rules are put in place for the learning environment because it ensures the safety of all persons in the lab and prevents any accidents from happening such as injuries and dangers. They also prevent dangers such as cross contamination and explosions from occurring.

A class without lab safety rules would be extremely dangerous and even deadly. People would get injured and many hazardous risks would come up. (like cross contamination, explosions, mentioned above). Injuries like blindness, burns, and cuts can occur. Just imagine a class of 2nd graders with no teacher around. that’s kind of like a lab without safety rules :)

hope that helps!

A. NE

B. NW

C. SE

D. SW

Answers

Answer: SW

Explanation:I got it wrong and it gives you the right answer so thats that

The direction of wind is SW direction. Hence option D is correct.

What is wind?

Wind is defined as the air movement brought on by the Earth's rotation and the sun's uneven heating of the surface. The uneven heating of the Earth by the sun and the rotation of the Earth result in wind, which is the movement of air. Light breezes to natural disasters like hurricanes and tornadoes are all types of winds. In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or polluting the environment.

An anemometer can measure wind speed, and a weather vane or wind vane can detect wind direction. When put with anemometers, many wind vanes can be installed in numerous locations to calculate the overall wind profile of a specific area.

Thus, the direction of wind is SW direction. Hence option D is correct.

Historically many ideas concerning cells have been examined leaving three to be incorporated into the cell theory which of the following is not part of the cell theory

Answers

Answer:all life form contains more than one cell

Explanation: thats the only question that's not true

Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

What is the significance of the theory behind the cell?

Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.

Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
