What is the equilibrium constant expression for the ksp of sr3(po4)2?
Eddi Din [679]

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)

You’ve just started a new job in the laboratory of the Food and Drug Administration. Your supervisor asks you to prepare a 1.50-
anastassius [24]

Answer:  118.5 grams

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n= moles of solute

V_s = volume of solution in ml = 500 ml

1.50=\frac{moles\times 1000}{500ml}

moles = 0.75

moles of solute =\frac{\text {given mass}}{\text {molar mass}}

0.75 =\frac{\text {given mass}}{158g/mol}

mass of KMnO_4 = 118.5 grams

Thus mass of KMnO_4 needed to prepare 500 mL of this solution iis 118.5 grams

What is one important role that ocean waters have in heating Earth?
Talja [164]

Answer:

Ocean temperature plays an important role in the Earth's climate system—particularly sea surface temperature (see the Sea Surface Temperature indicator)—because heat from ocean surface waters provides energy for storms and thereby influences weather patterns.
