28 Which compound is an electrolyte?
(1) CCl4 (3) C6H12O 6
(2) CH3OH (4) Ca(OH)2

Answers

Answer 1
Answer:  The answer is (4)Ca(OH)2. Electrolytes are substances that will ionize when dissolve in suitable ionizing solvents such as water. This includes such as salts, acids and bases. In the four choices, CCl4, C6H12O6 and CH3OH are nonpolar molecule.

How does the electron cloud model describe electrons

Answers

The electron cloud model describes electrons as the most likely found around the nucleus of an atom. It is also found that electrons could seemingly be everywhere at one time. Albert Einstein, Max Planck and Niels Bohr had done a research and have concluded that electrons transmit energy and that its properties are also linked to light and energy. 

The electron cloud model, also known as the quantum mechanical model, describes electrons as existing in regions of space around the nucleus called electron orbitals or electron clouds. These electron orbitals are three-dimensional probability distributions that represent the likelihood of finding an electron at a specific location.

According to this model, electrons do not follow precise paths like planets around the sun in a classical sense. Instead, they exist in a state of probability and can be found within certain regions around the nucleus with different levels of energy. These regions are defined by the principal quantum number (n), which corresponds to the electron's energy level or shell, as well as other quantum numbers that specify the shape, orientation, and spatial distribution of the orbitals.

Electrons are considered to have both particle-like and wave-like properties, and their behavior is described by the principles of quantum mechanics. The electron cloud model provides a more accurate and comprehensive description of the behavior and distribution of electrons in an atom compared to the older Bohr model, which depicted electrons as orbiting the nucleus in specific paths.

Hence, the electrons are described by the electron cloud model.

In any pure sample of CO2, the ratio of the mass of carbon to the mass ofoxygen is always the same. You can justify this ratio by the fact that
compounds are composed of which of the following?
A. Identical molecules created from atoms combined in whole
number ratios
B. Atoms whose chemical properties do not change during a
chemical reaction
O C. Atoms whose masses do not change during a chemical reaction
D. Different molecules which together produce the observed
elemental ratios

Answers

Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.

What ratio of Mass of Oxygen and Carbon?

  • Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are 32.0g of oxygen present for every 12.0g of carbon. By dividing 32.0 by 12.0, this simplifies to a mass ratio of oxygen to carbon of 2.66 to 1.
  • Carbon has an atomic weight of 12, oxygen in diatomic form(O2) of 32 and CO2 of 44. This means that the mass of 6x1023 atoms of CARBON has a mass of 6 kilograms, the mass of 6x1023 diatomic oxygen molecules is 32 kg, and for CO2 it is 44kg. So carbon is the lightest and CO2 the heaviest.

Identical molecules created from atoms combined in whole number ratios this is the best justification for In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same.
