Answer:
The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is TRUE.
Explanation:
The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is true because a compound can only be formed from the combination of two or more elements but not from one element.
The molecule formed from one carbon element (C) and 2 oxygen elements (O) is CO2. CO2 which is known as carbon(IV)oxide is a compound which is made up of carbon and oxygen elements.

Explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Function] f(x) = 6x + 1.5
[Given] f(2.5) is <em>x</em> = 2.5 for function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(2.5) = 6(2.5) + 1.5
- Multiply: f(2.5) = 15 + 1.5
- Add: f(2.5) = 16.5
