Explain whether a red apple is opaque or transparent and why it appears red.

Chemistry
1 answer:
aleksley [76]4 years ago

A red apple is opaque because you can’t see anything on the other side of the apple. The apple is red because the frequency of light shinning on it makes it seem that it is red, as it is reflected. It seems it is red because it reflects infrared waves.

(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.
