Question 6

The correct formula for ammonium tetracyanoplatinate(II) is ________

Accepted Answer

The correct formula for ammonium tetracyanoplatinate(II) is (NH4)2[Pt(CN)4], in which the ammonium ion NH4+ has a charge of +1 and the Pt(CN)4 ion has a charge of -2. To indicate this charge difference in the formula, the ammonium ion is written twice as (NH4)2. The correct formula contains the symbol for ammonium (NH4+), the symbol for tetracyanoplatinate(II) ([Pt(CN)4]2-), and the appropriate number of each to balance the charges.

Accepted Answer

Using the given equilibrium constant expression and stoichiometry:
K = [ClS1U1P1-S1S1P0]/([CuS1U1P1+S1S1P0][S1U1P1]^3[HCl]^3)
Plug in the values:
5 F1F1F1S1F1F1F10 10S1U1P15S1S1P0 = [ClS1U1P1-S1S1P0]/([CuNOS1U1B13S1U1B0][S1U1P1]^3[0.450 M]^3)
Solve for [ClS1U1P1-S1S1P0]:
[ClS1U1P1-S1S1P0] = 0.390 M

Question 11

The correct name for K₂[CuCl₄] is ________

Accepted Answer

The compound contains both potassium and copper, and the presence of "tetrachloro" in the name indicates that there are four chloride ions coordinated to the central metal ion. The Roman numeral in parentheses indicates the oxidation state of the metal ion, which is +2 in this case. Therefore, the correct name is potassium tetrachlorocuprate(II).

Accepted Answer

Fe(H₂O)₆³⁺ acts as an acid by donating a proton to water, which acts as a base by accepting the proton.

Question 20

What is the correct formula for hexamminecobalt(III) nitrite?

Accepted Answer

The formula for hexamminecobalt(III) is [Co(NH3)6]3+, where cobalt is in the +3 oxidation state and coordinated to six ammonia (NH3) ligands.
The formula for nitrite is NO2-, where nitrogen is in the +3 oxidation state and bonded to two oxygen (O) atoms.
To write the formula for hexamminecobalt(III) nitrite, we need to balance the charges of the two ions. 
Since hexamminecobalt(III) has a +3 charge, we need two nitrite ions to balance the charge, as each nitrite ion has a -1 charge. 
Therefore, the correct formula is [Co(NH3)6](NO2)2, which can be simplified to [Co(NH3)6](NO2)2. 
The only choice that matches this formula is C.
