Answer: Option (c) is the correct answer.

Explanation:

An ionic bond is defined as the bond which occurs when there will be transfer of electrons between the combining atoms.

For example, potassium donating an electrons to chlorine atom will result in the formation of an ionic bond.

So, the analogy presented by student C, shows that greedy dog stole away the bone from a smaller dog. This is similar to an atom whose one valence electron is readily taken away by an electron deficient atom.

Thus, we can conclude that out of the given options, student C: A big, greedy dog stealing away a bone from a smaller dog, presented a correct analogy.

What is the molality of a solution containing 3. 0 moles of nacl and 100. 0 moles of water?

Mama L [17]

The molality of a solution containing 3. 0 moles of NaCl and 100. 0 moles of water is 30 mol/kg.

The number of moles of solute in a solution equal to 1 kg or 1000 g of solvent is referred to as its molality. Mole per kilogram of solvent is the SI unit for molality.

Given:

3.0 moles of NaCl in 100 moles of water.

To find:

The molality of the solution

The moles of solute (NaCl) = 3.0 moles

The mass of solvent (water) = 100 moles (0.1 kg/mol)

Molality of a solution = Number of Moles of solute/ Mass of solvent(kg)

= 3.0 moles/0.1 kg/mol

= 30 mol/kg

1. Which is an example of pure chemistry? testing the effects of lower concentrations of a drug on humans developing a cure for

motikmotik

Answer:

studying chemicals containing carbon.

Explanation:

Pure chemistry can be regarded as

branch of science that's based on conduction of basic research so that

personal knowledge can be acquired. It can be reffered to as theoretical branch of chemistry, not applied branch. It comes with curiosity about something, how and why it happens. For instance, studying chemicals containing carbon is to gain knowledge there's no applied chemistry here

Propylene oxide is used to make many products, including plastics such as polyurethane. One method for synthesizing it involves

Vadim26 [7]

Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.

<h3>What is Lewis dot structure?</h3>

A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.

Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Classify what type of reaction occurred for hydrogen peroxide (there are 5 types you learned): A decomposition reaction occurred

Black_prince [1.1K]

Answer:

A Reaction of decomposition is ocurred to hydrogen peroxide.

Explanation:

Hydrogen peroxide is a molecule that can break down into Hydrogen and Oxygen or decompose very slow under moderate temperature, as you can see in the image below, hydrogen peroxide has a high electronic cloud that makes it a great oxidizer.
