Ray Of Light [21]3 years ago
3 0

<em>Answer:</em>

The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M

<em>Data Given:</em>

              Ksp of CaSO4 = 2.4 × 10∧-5

              CaSO4 ⇔ Ca+2   +  SO4∧-2

<em>Solution:</em>

                Ksp = [Ca+2].[ SO4∧-2]

                 2.4 × 10∧-5 = [x].[x]= x²

                 x =  4.9×10∧-3 M

<em>Result:</em>

  • The conc. of Ca+2 ion is 4.9×10∧-3 M

Charlie is balancing an equation. She has identified the atoms and counted the number of each in the reactants and products.
____ [38]

<u>Answer</u>:

Charlie adjust the coefficients to make the number of atoms in the reactants the same as the number of atoms in the

<u>Explanation</u>:

Stoichiometric coefficients are the number that appears before the symbol in each compound or element in the equation of a chemical reaction. By rule, it is positive for products and negative for reactants. Stoichiometric coefficients help in describing the stoichiometry of a chemical reaction.

According to "law of conservation of mass" that states "total reactant's mass equals the overall mass of obatined from the product". Thus, Charlie would adjust coefficients to equalise the number of atom in reactants and products.
