Answer:
The correct statements are :b, c , d, and e.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
K is the constant of a certain reaction when it is in equilibrium, while Q is the equilibrium quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
, reaction will move in forward direction and concentration of products will increase.
, reaction will move in backward direction and concentration of reactant will increase.
reaction is at equilibrium.
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
Nucleic acids typically contain phosphorous as well as nitrogen. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
The scientific meaning of salt is an ionic compound that is formed when an acid and a base reaction take place and is neutralized.
The common meaning of salt (table salt) is specifically the organic mineral of sodium chloride (NaCl) and is digestible.
Ionic salts are often not digestible (or not commonly digested, anyway)
