Alenkinab [10]3 years ago
3 0

Answer:

D. It has a specific set of possible values.

Explanation:

The best description of something that is quantized is that it has a specific set of possible values.

A quantized particle is discrete and can be assigned a value.

Max Planck was one of the pioneers fort the quantum theory of atoms where he suggested that electrons can be categorized based on their energy levels.

In physics quantization implies to be limited to some specific set of values which can be used to describe a quantity or particle

Which of the following compounds share electrons? NaCl CO CsF KBr
ArbitrLikvidat [17]
Covalent compounds share with each other, whilst Ionic compounds take from each other. 

Covalent compounds are composed of 2 or more NONMETALS.

So, it would be CO, since the rest of the compounds contain metals in them.

The reaction for producing glucose in plants, called photosynthesis, is:
Firlakuza [10]

Answer:

41.16 moles of H2O

Explanation:

Ratio for the products-reactants is 1:6, so 1 mol of glucose is produced when plants use 6 moles of water.

Then, let's make a rule of three:

1 mol of glucose is produce by using 6 moles of water

6.86 moles of glucose are produced by the use of (6 . 6.86)/1 = 41.16 moles of H2O

What is the molarity of a solution containing 7.47 moles of solute in 4.31 liters of<br> solvent?
scoray [572]

Answer:

1.73 M

Explanation:

Molarity is moles per liter, so we need to divide 7.47 moles by 4.31 liters to get the molarity of the solution.

7.47/4.31 ≈ 1.73 M

A chemist observes that a large molecule reacts as if it were much smaller. The chemist proposes that the molecule is folded in
nadezda [96]

Answer:

Hypothesis

Explanation:

The following steps are applicable when we wish to prove a specific fact:

  • a hypothesis is made; this is a statement that we provide after some observations and we wish to either prove or deny it;
  • multiple experiments are carried out in order to gather significantly substantial amount of data that can be then further analyzed and any tendencies can be noticed;
  • based on the data gathered, conclusions are made: we either prove or deny the hypothesis. If hypothesis is proved, it may become a theory over long time.

In the context of this problem, we're at the first step where we make a hypothesis.
