What is the equilibrium constant expression for the ksp of sr3(po4)2?

Chemistry
2 answers:
Eddi Din [679]3 years ago
7 0

The equilibrium constant expression for KSP of Sr3(PO4)2 is


KSP={(Sr^2+)^3 (PO4^3-)^2/ Sr3(PO4)2}


Explanation


write the ionic equation for Sr3(PO4)2


Sr3(PO4)2 → 3Sr^2+ + 2 PO4^3-


KSP is given by (concentration of the products raised to their coefficient /concentration of reactants raised to their coefficient)

What is the hybridization of the central atom in the trichlorostannanide anion?
Mademuasel [1]

Answer:

sp²

Explanation:

The trhichlorostannanide anion has molecular formula SnCl₃⁻, Sn is the central atom, which is at the group 14 of the periodic table, so it has 4 valence electrons. It must form 4 bonds to be stable.

In the anion, the tin (Sn) forms 3 bonds, so, it has 1 electron that is isolated. According to the VSEPR theory, the geometry of a molecule depends on the bonded electrons and the lone pairs, because the repulsive force between them will form the angles of the molecule.

Thus, only the bonded electrons will contribute, and because of that, the geometry will be trigonal planar.

To form the bonds, the subshells (s, p, d, f) of the atoms in the bond must interact. But, only isolated electrons can bond, so, to be stable and form the compounds, some atoms have hybrids shells, which are formed by the join of subshells.

The hybridization can be found by the determination of how many bonds are done, or by the geometry. For a trigonal planar geometry, the hybridization is sp², which means that the orbital is formed by one orbital s and two orbitals p.

When the equation Al(OH)₃ + H₂SO₄ ---> Al₂(SO₄)₃ + H₂O is balanced, the sum of the balancing coefficients is
denis-greek [22]

Answer:

The answer to your question is the letter D. 12

Explanation:

Unbalanced chemical reaction

               Al(OH)₃  +  H₂SO₄  ⇒   Al₂(SO₄)₃  +  H₂O

           Reactants              Elements         Products

                  1                            Al                      2

                  1                            S                       3

                  5                            H                      2

                  7                            O                      13

Balanced chemical reaction

              2Al(OH)₃  +  3H₂SO₄  ⇒   Al₂(SO₄)₃  +  6H₂O

           Reactants              Elements         Products

                  2                            Al                      2

                  3                            S                       3

                 12                            H                     12

                 18                            O                     18

Sum up the coefficients

Result = 2 + 3 + 1 + 6

          = 12

Describe the energy in coal and the way in which it’s converted to electrical energy. Write 50 to 100 words.
devlian [24]

Answer:

Coal contains chemical potential energy

Explanation:

Chemical species are known to contain chemical energy. Chemical energy is contained in chemical bonds in a chemical substance.

Since energy can neither be created nor destroyed, energy contained in chemical bonds can be transformed from one form to another. Coal contains chemical energy.

One of the ways of generating electricity is the combination of fossil fuels. This involves the conversion of chemical energy to heat energy. The steam produced is used to turn a turbine. The turning off the turbine implies a conversion of heat to mechanical energy. The turning of the turbine now produces electrical energy.

A 3.540-g sample of an unknown metal M is burned in the presence of excess oxygen, producing the oxide M2O3(s) and liberating 18
pshichka [43]

Answer:

a) Sm

Explanation:

Hello,

This substantiation could be done by knowing how to compute the released energy for 1 mol the oxide. Thus, for Sm, the computation turns out into:

Q=-1823.0\frac{kJ}{mol}*\frac{1molSm_2O_3}{348.72gSm_2O_3} *3.540gSm_2O_3\\Q=-18.5kJ

The sign just indicates that the heat is released due to the chemical reaction and it matches with the indicated heat in the statement.

Best regards.
