What is the equation for concentration with Solutes and Solvents?​

Chemistry
1 answer:
QveST [7]3 years ago
5 0

Answer:

 Molarity = no. of moles of solute / Liter of solution

  Molality = no. of moles of solute / Kilogram of solvent

Explanation:

Solvent: Solvent is a liquid that dissolve the solute. in most cases it is water but some time other liquids gases can also be a solvent.solvent have the ability to dissolve solute and in larger volume than solute.

Solute:

It is the substance that is in less amount than solvent and dissolve in it

Solution:

When solvent and solute combines, the solute get dissolved in it and it form a solution.

Concentration:

It is to represent or describe the property of solution and refer to the amount of one constituent per total mixture or solvent.

There are two terms to represent the concentration in terms of solute and solvent.

Molarity:

It the amount of solute in moles dissolved per liter of solution. it can be represented by the following equation

         Molarity = no. of moles of solute / Liter of solution

Molality:

It is the amount of solute in moles dissolved per kilogram of solvent. it can be representd by the following equation

           Molality = no. of moles of solute / Kilogram of solvent

Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain.
mamaluj [8]

Answer: C) Tetrahedral

Explanation:

The number of electron pairs is 4 that means the hybridization will be sp^3 but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.

Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be sp^2.

Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be sp^3.

Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be sp^3d.

Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be sp^3d^2.

Write a balanced equation for its combustion reaction.
laila [671]
<h3>Answer:</h3>

C₅H₁₂O(l)+15/2O₂(g)→5CO₂(g)+6H₂O(l)

<h3>Explanation:</h3>

The balanced chemical equation for the combustion of the hydrocarbon in question is;

C₅H₁₂O(l)+15/2O₂(g)→5CO₂(g)+6H₂O(l)

  • A balanced chemical equation is one in which the number of atoms of each element is equal on both sides of the equation.
  • In this case;
  • Reactant side has; 5 carbon atoms, 12 hydrogen atoms and 16 Oxygen atoms
  • Product side has; 5 carbon atoms, 12 hydrogen atoms and 16 Oxygen atoms
  • An equation is balanced by putting appropriate coefficients on reactants and products involved in the reaction.
  • An equation is balanced so as to obey the law of conservation of mass.
