Serga [27]4 years ago
5 0

Period

Group

Explanation:

On the periodic table the numbers 1,2 and 3 can represent either groups or periods.

The periodic table gives the arrangement of elements based on their atomic numbers

  • They are divided into vertical columns and horizontal rows
  • The vertical columns are the groups whereas the horizontal rows are the periods.
  • The vertical columns are made up of elements having the same number of electrons in their outermost shell.
  • The horizontal columns are made up of elements having the same number of shell.
  • On the periodic table, the groups are numbered 1 - 18
  • There are 7 periods on the table.

Which of these compounds would you expect to be most soluble in water? ch3ch2cl ch3ch2ch2ch3 ch3ch2ch2f ch3ch2ch2oh?
Montano1993 [528]

Answer : The compound that would be most soluble in water is CH3CH2CH2OH

Explanation :

Water is a polar solvent and can dissolve polar molecules. This is based on the principle "Like dissolves like".

Among the given molecules, CH3CH2CH2CH3 is a hydrocarbon known as butane. All hydrocarbons are non polar. Therefore this compound will not be soluble in water.

The remaining compounds are polar, but Ch3CH2CH2OH shows greater solubility in water owing to presence of hydrogen bonding.

Hydrogen bonding is a type of intermolecular force that gets formed when a compound has hydrogen atom directly attached to highly electro-negative N, F or O atom.

When CH3CH2CH2OH is dissolved in water, it forms hydrogen bonds with water molecules. Due to this hydrogen bonding, the molecule shows greater solubility.

Therefore CH3CH2CH2OH is the most soluble compound in water

How many grams of Aspirin (acetylsalicylic acid) should we form in this reaction if we started with 2.08g of Salicyclic Acid?
Kamila [148]

Taking into account the reaction stoichiometry, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

C₄H₆O₃ + C₇H₆O₃ (Salicyclic Acid) →C₉H₈O₄ (aspirin) + C₂H₄O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • C₄H₆O₃: 1 mole
  • C₇H₆O₃: 1 mole
  • C₉H₈O₄: 1 mole
  • C₂H₄O₂: 1 mole

The molar mass of the compounds is:

  • C₄H₆O₃: 102 g/mole
  • C₇H₆O₃: 138 g/mole
  • C₉H₈O₄: 180 g/mole
  • C₂H₄O₂: 60 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

  • C₄H₆O₃: 1 mole ×102 g/mole= 102 grams
  • C₇H₆O₃: 1 mole ×138 g/mole= 138 grams
  • C₉H₈O₄: 1 mole ×180 g/mole= 180 grams
  • C₂H₄O₂: 1  mole ×60 g/mole= 60 grams

<h3>Mass of aspirin formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 138 grams of salicyclic acid form 180 grams of aspirin, 2.08 grams of salicyclic acid form how much mass of aspirin?

mass of aspirin=\frac{2.08 grams of salicyclic acidx 180 grams of aspirin}{138 grams of salicyclic acid}

<u><em>mass of aspirin= 2.713 grams</em></u>

Then, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

How can the concentration of a solution be changed
Vlad1618 [11]

The mass of the salt converted into moles divided by the liters of water in a solution would give the Molarity (M) or concentration of the solution. The simplest way to change the solution would be to change the amount of solute or solvent in a solution.
