The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
The leaf would be on top of the wave after two seconds just like it was positioned at 0 seconds. After 3 seconds the leaf should be positioned like it was at 1 second. The leaf is moving along with the wave.
<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 smaller number is the number of protons, and the greater number is the mass.
