Certain "rules" of chemistry are used to simplify concepts when in fact sometimes these rules are often "broken." Place the prop

er word into each sentence illustrating some of these exceptions.

Chemistry
1 answer:
True [87]3 years ago
4 0

Answer:

The question is incomplete but this is the complete question in picture format.

Explanation:

1. An ION is the violation of the rule that suggests that electron and proton will be equal in number for each atom.

2. An ISOTOPE violates the rule that number of neutrons always equals the number of protons.

3. The original term ELEMENT meant to be indivisible, a term that doesn't consider the modern understanding of atom splitting and radioactive decay.

4. Often depicted with a central nucleus with concentric rings housing electrons, the ORBITAL models incorrectly conveys the idea that electrons rotate around the nucleus in a predictable orderly fashion.

5. The large number of naturally existing isotopes violate the rule that adding the number of neutrons and protons will yield and accurate ATOMIC weight.

Control activities are performed within processes (e.g., segregation of duties required in processing cash receipt transactions)
galina1969 [7]

Answer:

a. True

Explanation:

The control objectives seek to support the fulfillment of the critical factors of business success, in order to finally support the achievement of the institutional objectives, on this the CITI is based

It is very important to clearly identify the relationships of the control objectives with other internal control elements such as:

 · Critical success factors receive direct support from control objectives to support compliance.

· The control objectives are made up of control goals, which allow them to have a more detailed perspective of the control objectives and at the same time facilitate the evaluation of their compliance.

CITI CONCEPT:

It is the set of administration elements that a company establishes in a coordinated way so that the use of information technology resources effectively supports the institutional objectives of the company

Scientist looking for new substances in plants grind up the plants with methanol. This solvent dissolves many plant compounds. H
liubo4ka [24]

Answer:

See explanation

Explanation:

Crystals can be made from methanol by recrystallizing the plant extract from methanol.

The methanol/water system is heated rapidly using a hot plate and the plant extract dissolves in the heating solution until a clear solution is obtained.

The solution is now cooled rapidly. The interior of the flask used for the re crystallization may even by scratched to assist the quick formation of crystals. Large crystals of plant compounds may be obtained using this method. This process should be carried out in a fume hood because of the toxicity of methanol.

A glucose solution that is prepared for a patient should have a concentration of 180 g/L. A nurse has 18 g of glucose. How
Irina-Kira [14]
<h3>Answer:</h3>

0.10 L

<h3>Explanation:</h3>

The concentration of glucose  is given as 180 g/L

The mass of glucose is 18 g

  • Concentration in g/L is calculated by dividing mass of the solute by the volume of the solution.
  • When calculating molarity on the other hand, we divide number of moles of the solute by the volume  of the solution.
  • Concentration in g/L = Mass of solute ÷ Volume

Rearranging the formula,

Volume = Mass of the solute ÷ concentration

             = 18 g ÷ 180 g/L

            = 0.10 L

Therefore, volume of water is 0.10 L
