Answer:
2-octene
Explanation:
the 8-carbon chain (oct); has a double bond (ene) is on the 2nd carbon (2-)
The volume of the gold chain is 4.18 cm³
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can determine the volume of the chain. Details below:
<h3>How to determine the volume of the gold chain</h3>
The following data were obtained from the question:
- Mass of gold = 80.7 g
- Density of gold = 19.3 g/cm³
- Volume of gold chain =?
Density = mass /volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
Volume of gold chain = 80.7 / 19.3
Volume of gold chain = 4.18 cm³

Answer:
A. The human body can break down complex carbohydrates into sugar molecules that provide energy.
Explanation:
Strings of glucose, form complex carbohydrates such as starch and glycogen. Glycogen which is a stored form of glucose in humans is a source of long-term energy, and a complex carbohydrate because glycogen can be converted to glucose-1-phosphate which can enter the glycolytic cycle to generate Adenosine triphosphate which is a unit of energy.
This stored form of energy can be slowly broken down to release energy when needed by the body. During exercise, for instance, glycogen can slowly release ATP needed for energy.
Answer is B
It is strongly ionizing and cannot penetrate dense materials.
