Answer:
B.
General Formulas and Concepts:
<u>Chemistry - Organic</u>
- Hydrocarbons
- Bond-Line Notation: Each "arrow" point represents a carbon and the lines represent a bond between the carbons. Hydrogens are assumed added when drawing the molecular formulas
Explanation:
We are given C₈H₁₈. We need a Bond-Line notation where there are 8 "arrow" points (which represent Carbon). We can disregard the Hydrogens as they are assumed to take the rest of the bonds.
Only option B has a value of 8 carbons, represented by the "arrow" points. Therefore, it is the correct answer.
A homogeneous mixture<span> has the same uniform appearance and composition throughout. Many homogeneous </span>mixtures<span> are commonly referred to as </span>solutions<span>. A </span>heterogeneous mixture <span>consists of visibly </span>different<span> substances or phases. The three phases or states of matter are gas, liquid, and solid.

Answer:
endoplasmic reticulum:
✔ helps in the production and movement of materials
Golgi body:
✔ packages and distributes materials in and out of cell
mitochondrion:
✔ supplies energy that the cell uses
ribosome:
✔ produces proteins for the cell
Explanation:
took test :D
H₂ + CO₂ ⇄ CO + H₂O
1 mol H₂ - 1 mol H₂O
x mol H₂ - 30.6 mol H₂O
x=30.6*1/1=30.6 mol (<span>theoretically)</span>
