5. What is the overall charge of the electron cloud of the atom?Explain

Chemistry
1 answer:
Basile [38]2 years ago
8 0

The answer is: The overall charge of the electron cloud is negative,

Electron: Electron is a sub-atomic particle which is found outside the nucleus of an atom. The charge carried by an electron is negative.

What is the electron cloud and who suggest this idea?

  • Erwin Schrödinger developed electron cloud model.
  • He suggested that atoms have a central nucleus made up of protons and neutrons. Around it is the "probability region" where electrons are most likely to be found.
  • The higher the density, the more likely the electron will be found in this region.
  • This dense probability region is called an electron cloud.
  • As this region carries only negatively charged electrons, thus the overall charge of the electron cloud is negative.

Select the correct Answers.
Mandarinka [93]

Answer:

3. The temperatures of the two substances equalize.

Explanation:

  • As two objects at different temperatures are placed in contact, heat is transferred from the warmer to the cooler object until the temperature of the two objects be the same.
  • The amount of heat that is transferred from the warmer object is equal to the amount of heat that is transferred into the cooler object.
  • This is in agreement with the law of conservation of energy.
  • <em>So, the right choice is: 3. The temperatures of the two substances equalize. </em>

Suppose that a certain fortunate person has a net worth of $77.0 billion ($). If her stock has a good year and gains $3.20 billi
marissa [1.9K]

Answer:

New net worth to three significant figures = $80.2 billion

Dollars are given to charity = $100,250,000

Explanation:

Net worth = $77.0 billion

stock Gains = $3.20 billion

New net worth = $77.0 billion + $3.20 billion = $80.20 billion

New net worth to three significant figures = $80.2 billion

One-eighth of a percent = (1/8 x 1) / 100 = 0.00125

Dollars are given to charity = 0.00125 X $80.2 billion = $100,250,000

Or

$80,200,000,000/100 = $802,000,000

Answer:

Cu2+(aq) + 2OH-(aq) => Cu(OH)2(s)

Explanation:

Use of aqueous sodium hydroxide is a precipitation reaction to test for anions or cations. Aqueous sodium hydroxide in a precipitate test forms a insoluble precipitates along with some colors characteristics.

Aqueous sodium hydroxide (NaOH) when mixed with copper(II) (Cu2+) forms a blue precipitate. The formula is as follows:

Cu2+(aq) + 2OH-(aq) => Cu(OH)2(s)
