Answer:
Explanation:
Columns and rows used in the periodic classification of elements shows trends in the properties of elements.
The periodic columns are called groups and they denote vertical arrangement of elements.
The horizontal rows are the periods.
- Groups and Periods provides a very simple way to classify elements.
- They reflect trends among different elements that are found in nature. Following these groups and periods, it is even possible to predict the nature of an undiscovered element.
- Certain parts of the table have some unique elements on them with some distinctive properties that distinguish them from others.
- The atomic number is the basis of this classification. By this, it is possible to delineate that elements with similar properties are located on the same group.
The Ka of the acid is 1.3 * 10^ -7.
Ka is the constant of dissociation of the acid.
Kb is the constant of dissociation of the conjugated base
The relationship between Ka and Kb is:
Ka * Kb = Kw = 1 * 10 ^-`14
=> Kb = Kw / Ka
=> Kb = [1 * 10 ^ -14 ] / [1.3 * 10 ^ -7] = 7.69 * 10 ^-8 = 7.7 * 10 ^ -8
Answer: 7.7 * 10^-8
A supersaturated solution more solute then what the solute can hold at a certain temperature. So the solution in this example is contain 5g more than the amount the water can hold so it is supersaturated. Hope this held!
Answer:
About bonding
Explanation:
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bond.
I will say it will be B. the maximum energy required to remove one electron from an atom... hope that help
