An oxygen atom picks up two additional, free floating electrons. Is the charge of the newly formed oxygen ion positive, negative or neutral?

Answers

Answer 1

Answer:

Answer:The newly formed oxygen ion is negatively charged.

Explanation:

Cation : These are species of ions which carries positive charge that is number of protons are greater than the number of electrons.

Anion:These are species of ions which carries negative charge that is number of electrons are greater than the number of protons.

$O+2e^-\rightarrow O^(2-)$

When an oxygen atom gains two electrons it develops the charge of negative charge and forms anion.

Answer 2

Answer: i believe it would be negative as electrons carry negative energy

hope this helps :)

Which of the following types of energy originates below Earth's surface?A. electrical energy
B. geothermal energy
C. mechanical energy
D. electromagnetic energy

Answers

Geothermal energy. Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made. I hope this answer and these explanations helped!

Is adding sugar to lemonade a chemical or physical change

Answers

physical.. think of it as a person putting on weight.. adding weight, but still a person. adding sugar, but still lemonade.

That's a physical change since nothing's really happening except for the flavor. Only the flavor changed cause you added something, but it's not a chemical

Evelyn learns that a sound wave can be recorded electronically as an analog signal or as a digital signal. She investigates these two signal types. She records her voice using a tape recorder, which uses an analog signal to produce sound when played back. She also records her voice using a computer, which uses a digital signal to produce sound when played back. Evelyn replays each recording 100 times.a. Describe a difference that Evelyn would most likely hear between the two recordings after being replayed 100 times.

b. Explain why the two recordings would sound different after being replayed 100 times.

Answers

a)The analog signal'spitch and frequency change each time. It is continuous in the digital signal.

What is the digital signal?

A digital signal is one in which data is represented as a series of discrete numbers.

To reduce the influence of noise in communication, a digital signal is utilized. When compared to analog signals, digital signals convey more information per unit of time.

a)Evelyn would most likely notice a difference between the two recordings after hearing them 100 times is that the analogsignal's pitch and frequency change each time. It is continuous in the digital signal.

b)After 100 replays, the two recordings would sound different since the digital signal has a greater quality throughout long-distance transmission.

When digital signals are transferred, the amount of bandwidth used is lowered.

Hence, the digital signal has a greater quality throughout long-distance transmission causing two recordings would sound different.
