What is a safety guide line?

In order to use the gas laws, all temperatures must be in the _ scale.

belka [17]

Kelvin. Kelvin is the scientific term used in temperature senses, and was created so everybody around the world would have the same measurements and not get confused about whether it was Fahrenheit or Celsius.

Will has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has gl

Aleks04 [339]

Answer:

The aquarium is covered and not in sunlight

Diminishing

Explanation:

The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.

Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.

This food provides all other lives with energy through the break down of energy held in carbon chains.

Is the aquarium now in sunlight or is it covered?

Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.

Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.

The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.

What is happening to the number of energy storage molecules in the plants and fish as a result?

The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.

This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.

Match: Substance ....... Definition Lewis acid A. Provides H+ in water Bronsted-Lowry base B. Provides OH - in water Arrhenius b

Igoryamba

Answer: F. Electron pair acceptor

Explanation:

A Lewis acid can be properly defined as any substance such as H+ (hygrogen ion) that can accept a pair of electron.

While a Lewis base is any substance such as (OH-) that can donate a pair of electron.

In the neutralization reaction between an acid ( H+ ) and a base (OH-). Hydrogen ion (H+ ) is the Lewis acid because it accepts an electron pair from (OH-).

Other examples of Lewis acid are; Mg2+, K+

Answer:

Option A is correct.

Atomic orbitals developed using quantum mechanics describe regions of space in which one is most likely to find an electron

Explanation:

Atomic orbitals developed using quantum mechanics make use of quantum numbers.

There are four different quantum numbers that all work to give the region of space where a particular electron has the highest probability of being located.

The four quantum numbers that describes an electron's most likely location in an atom include

1) Principal quantum number, denoted by letter n. This quantum number gives the shell that an electron in an atom belongs to. It can take on natural number values from 1 (for the shell closest to the nucleus) through 2, 3, 4.... till rhe outermost shell.

2) Azimuthal/Angular Momentum quantum number, denoted by l. This quantum number describes the subshell or orbital within a shell that the electron belongs to in an atom.

It can take on values that can range from 0 to (n-1). These are the spdf orbitals with s-orbital having l-quantum number of 0, p-orbital with l-quantum number of 1 etc.

3) Magnetic quantum number, denoted by letter m. This describes the sub-orbital that the electron belongs to. It's values for electrons in a particular orbital vary from -l through 0 to +l.

E.g. orbital with l = 1 has electrons whose magnetic quantum number vary from -1, 0, +1.

orbital with l = 2 has electrons whose magnetic quantum number vary from -2, -1, 0, +1, +2.

4) Spin quantum number, denoted by letter s.

This describes the orientation of the electron's spin. Whether clockwise or anti-clockwise in it's sub-orbital. It can take on only values of (+1/2) or (-1/2).

So, these four quantum numbers, numbers that were made known because of quantum mechanics, show that atomic orbitals developed using quantum mechanics describe regions of space in which one is most likely to find an electron in an atom.

Hope this Helps!!!
