Answer:
This solution acts as an efficient buffer
Explanation:
the pH of a buffer solution can be described like this:
[acid]=[acetic acid]=
[base]=[sodium acetate]=
replacing,
If we add an acid, pH will decrease a little bit and if we add a base, pH wil increase a little bit.
lets supose that we change the rate by increasing [base] to 0.1, then
and now lets supose that we increase [acid] to 0.1
Big changes in concentration of base or acid doesn´t produce big changes in pH, in that way the mix of sodium acetate with acetic acid is a good buffer solution.
Answer:
No, CCl₄ is 4 covalent C-Cl single bonds with a Tetrahedral geometry.
Explanation:l
For resonance structures to exist the molecule must have alternating single-double bonds. H₂C = CH - CH₃ <=> H₃C - CH = CH₂ resents a simple compound with a resonance structure system. This means that the π-bond electrons are distributed across all carbons in the molecular backbone. I would recommend internet searching for Danial Weeks 'Pushing Electrons' for a comprehensive review of molecular resonance structures. It is a brief, but easy to follow treatment of simple to complex structures containing resonance systems.
Hope this helps. Doc :-)

4) size
<h3><u>Explanation</u>;</h3>
- The mineral’s physical properties are used in identifying minerals and are determined by its chemical composition and crystal structure.
- <u>Streak</u> is the color of the mineral in powdered form and since it is a more accurate illustration of the mineral’s color, its is a more reliable property of minerals than color for identification.
- <u>Hardness</u> is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral’s resistance to scratching.
- <u>Density</u> may be used to identify minerals. It is used to describe the amount of matter in a certain amount of space. Substances that have more matter packed into a given space have higher densities.
Rift Valley Examples
- East African
- Rhine Rift Valley (Germany)
- Baikal Rift Valley (Russia)
Rift Valley Facts/Characteristics
- Bordered by fault zones and separating land masses
- A portion of land that drops, forming a valley.
- Formed as tectonic plates move.
Fossils - Examples
- Bones
- Shells
- Exoskeletons
- Stone imprints of animals.
Non Examples of Fossils
- Stones
- rocks
- Some bones (If they are fossils they will be a lot heavier than other bones.
