Answer:
C. Aqueous Solutions
General Formulas and Concepts:
<u>Aqueous Solutions</u>'
- Dissociation
- Solvents and Solutions
Explanation:
Water is the universal solution that solvents are dissolved in. Whenever anything is dissolved in water, it will be an aqueous solution.
Strong ionic solutions dissolve into their ions when dissolved in water.
Weak acids and bases don't fully dissociate in water.
I think it might be a gas was formed.
Hope I'm right and it helps you out!!
The correct answer is 0.72 g/cm3
Explanation:
The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:



This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3
Just 2 valence electrons.
Hydrogen already has one to start with, as well. With the exception of hydrogen and helium, all other atoms need 8 valence e-
