Answer:
7.7×10^-6
Explanation:
CoCO3(s)<--------> Co^2+(aq) + CO3^2-(aq) Ksp= 1.0 ×10 ^-10
Co^2+(aq) + 6NH3(aq) <-----------> [Co(NH3)6]^2+. Kf = 7.7×10^4
Overall:
CoCO3(s) + 6NH3(aq) <--------> [Co(NH3)6]^2+(aq) + CO3^2-(aq) Knet= Ksp× Kf
Knet= Ksp× Kf = 1.0 ×10 ^-10 ×7.7×10^4= 7.7×10^-6
The insoluble CoCO3 dissolves in the presence of ammonia because bof the formation of hexamine cobalt II complex ion.
From the addition of 1 equivalent of HBr to 1,3-butadiene, 3-bromo-1-butene is obtained as a product.
What is moles?
Moles are defined as the smallest base unit that is equivalent to units.
Moles are chemical entities, which are used to measure the mass or molecular mass of the compound, molecule, or atom. The moles are, for example can be explained as equal to the mass of the atom. For example, there is one mole in 12 grams of carboncarbon.
Thus the kinetic product formed is 3-bromo-1-butene.

D, Urine.
Just google what sweat is made of and it gives you all of the answers except for urine. Also you’d probably smell really bad if your sweat had urine in it. Hope this helps! :)

Answer:
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
