acetaminophen is a stronger acid than methanol, and sodium methoxide is a stronger base than. write an acid base equilibrium rea
torisob [31]

Answer:

The equilibrium shifts to the right that is the forward reaction.

Explanation:

The chemical compound known as "Acetaminophen" is a chemical compound that is generally known to a layman as Paracetamol and it belongs to the drug class known as anagelsics which helps in the treatment of pain or say in the reduction of pain. Acetaminophen has the chemical Formula to be C8H9NO2, with the Molar mass of 151.163 g/mol and Boiling point of 420 °C.

The reaction between Acetaminophen and sodium methoxide gives methanol and acetaminophen sodium salt. Therefore, the acid base equilibrium reaction of these species is given as;

C8H9NO2 + CH3ONa <========> CH3OH + acetaminophen sodium salt.

The equilibrium shifts to the right that is the forward reaction.

Consider the solution containing 0.181 M lead ions and 0.174
Luba_88 [7]

Answer:

[ S2- ] = 4.0 E-47 M

Explanation:

  • PbS(s) → Pb2+  +  S2-
  • HgS(s) → Hg2+  +  S2-

∴ Ksp PbS = 3.4 E-28 = [Pb2+]*[S2-]

∴ [Pb2+] = 0.181 M

∴ Ksp HgS = 4.0 E-53 = [Hg2+]*[S2-]

∴ [Hg2+] = 0.174 M

∴ Ksp PbS > Ksp HgS ⇒ precipitate first Hg2+:

∴ [ Hg2+ ] = 1.0 E-6 M

⇒ [S2-] = 4.0 E-53 / 1.0 E-6 = 4.0 E-47 M

a rectangular piece of aluminum foil measures 13.72 cm x 8.63 cm and has a mass of 3.1 g. Find how thick it is
Leona [35]

The two dimensions of aluminum foil are given 13.72 cm and 8.63 cm respectively with mass  3.1 g.

The density of aluminum is 2.7 g/cm^{3}. It is defined as mass per unit volume thus, volume of aluminum can be calculated as follows:

V=\frac{m}{d}

Putting the values.

V=\frac{3.1 g}{2.7 g/cm^{3}}=1.148 cm^{3}

The volume of cuboid is l\times b\times h, the length and breadth are given, height can be calculated as follows;

h=\frac{V}{l\times b}

Putting the values,

h=\frac{1.148 cm^{3}}{(13.72 cm)(8.63 cm)}=0.009695 cm

Or, approximately 9.7\times 10^{-3}cm

Therefore, thickness of aluminum foil is 9.7\times 10^{-3}cm

]Which of the following would you expect to form an ionic bond when combined?
grigory [225]
Ionic bonds is formed between metal and nonmetal with opposite charges. Metal have (+) charge and nonmetals often have (-) charge. 

Choice (a) is wrong because both charges are the same. 
Choice (c) is wrong b/c same changes. 
Si and O do not have charges for now. (d) is wrong. 

Choice (b) is correct. Opposite charges and the ionic compound is BaCl2
