Why aren't descriptive investigations repeatable?

Chemistry

Answer:

Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.

I would say that descriptive investigations aren't repeatable because it means that you are only describing something - you ask certain question about something, but do not form a hypothesis at that point yet. So it would be a waste of time to simply ask the same questions over and over again with no hypothesis to prove, which is why these types of investigations cannot be repeated.

Answer:

Model B

Explanation:

Model A shows that light has been reflected, whereas Model B shows the light has been refracted. Light will be refracted as the light enters a more dense medium (glass), from a less dense medium (air).

This website has a really useful, thorough explanation for why this occurs:

(Check the explanation under the heading 'Explaining refraction - Higher')

(iii) Calculate the volume of carbon dioxide at room temperature
avanturin [10]

The combustion of 30.0 g of glucose at room temperature and pressure produces 24.0 L of carbon dioxide.

<h3>What is combustion?</h3>

It is a reaction in which a substance burns with oxygen to form carbon dioxide and water.

Let's consider the combustion of glucose.

C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O

First, let's convert 30.0 g of glucose to moles using its molar mass.

30.0 g × 1 mol/180.16 g = 0.167 mol

The molar ratio of C₆H₁₂O₆ to CO₂ is 1:6. The moles of carbon dioxide produced are:

0.167 mol Glucose × (6 mol CO₂/1 mol Glucose) = 1.00 mol CO₂

1 mol of an ideal gas at room temperature and pressure occupies 24.0 L.

The combustion of 30.0 g of glucose at room temperature and pressure produces 24.0 L of carbon dioxide.
