Answer:
16
Explanation:
FIRST AND FOREMOST, BALANCE YOUR EQUATION.
Al + S8 ➡️ Al2S3
Numbers of Al=1. ➡️ Numbers of Al = 2
Numbers of S =8. ➡️ Numbers of S. = 3
USE COEFFICIENT TO BALANCE THE EQUATION.
16Al + 3S8 ➡️ 8Al2S3
Now the Numbers of Al and S in both sides of eqn. is balanced
The Answer Is 16
<h3><u>Answer;</u></h3>
Hydrogen bonding causes water to be strongly cohesive.
<h3><u>Explanation;</u></h3>
- The strong hydrogen bonds give water a high cohesiveness and, consequently, surface tension.
- Hydrogen bonding makes ice less dense than liquid water and since ice is less dense than water, it is able to float at the surface of water.
- Water is considered the universal solvent due to its ability to dissolve or dissociate most compounds, a property that results from its polarity, where oxygen has a higher electronegativity than hydrogen.
The best answer among the choices given is option A. Chemical weathering of rocks is a source of dissolved substances in the ocean. It is a process that involves the erosion of rocks due to chemical reactions by water and substances dissolved in the water. Therefore, it most likely the source of dissolved substances.
