The molar solubility is the Pb ions present. PbCO3 dissociate to form Pb ions and CO3 ions
Ksp 7.40x10^-14 is equal to (Pb ions) (CO3 ions)
Pb ions correspond to CO3 ions
(pb ions)( Pb ions) is equal to 7.40x10^-14
therefore Pb ions is square root of 7.4x10^14 which is 2.27x10^-7m
In g/l is (2.27x10^-7) x 267(RFM of PbCO3) which is 6.06x10^-5 g/l
MgSO₄ + Pb(NO₃)₂ = PbSO₄(s) + Mg(NO₃)₂
Mg²⁺ + SO₄²⁻ + Pb²⁺ + 2NO₃⁻ = PbSO₄ + Mg²⁺ 2NO₃⁻
Pb²⁺ + SO₄²⁻ = PbSO₄
B. Unless you melt the solid the solid will hold its form
Answer is: there are ten atoms in one molecule of antifreeze.
One molecule of ethylene glycol (C₂H₄(OH)₂) has two carbon atoms, six hydrogen atoms (4 + 2 · 1) and two oxygen atoms (2 · 1). So there are:
2 + 6 + 2 = 10 atoms.
Ethylene glycol (C₂H₄(OH)₂) is an odorless, sweet-tasting, colorless viscous liquid.
Answer: compound
Explanation: because the hydrogen molecules and the oxygen molecules are chemically bonded together unlike in a mixture
