Accepted Answer

### Problem 1
#### Part a
# Explanation:
## Step1: Identify elements and prefixes
Sulfur (S) has no prefix (mono), hexabromide means 6 bromine (Br) atoms.
## Step2: Write formula
Combine symbols with subscripts: $ SBr_6 $ (already correct as per the handwritten, but let's confirm: sulfur is S, bromide is Br, hex- means 6, so $ SBr_6 $ is correct).

#### Part b
# Explanation:
## Step1: Identify elements and prefixes
Oxygen (O) has no prefix (mono), pentafluoride means 5 fluorine (F) atoms.
## Step2: Write formula
Correct formula should be $ OF_5 $ (the handwritten "OFI" is incorrect; F is fluorine, so $ OF_5 $).

#### Part c
# Explanation:
## Step1: Identify elements and prefixes
Trinitrogen means 3 nitrogen (N) atoms, octachloride means 8 chlorine (Cl) atoms.
## Step2: Write formula
Combine: $ N_3Cl_8 $.

### Problem 2
#### Part a
# Explanation:
## Step1: Identify elements and subscripts
$ Se_8O_7 $: Se is selenium, O is oxygen. Subscripts: 8 selenium, 7 oxygen. Prefixes: octa- for 8, hepta- for 7.
## Step2: Name the compound
Octaselenium heptoxide.

#### Part b
# Explanation:
## Step1: Identify elements and subscripts
$ Si_2Cl_9 $: Si is silicon, Cl is chlorine. Subscripts: 2 silicon, 9 chlorine. Prefixes: di- for 2, nona- for 9.
## Step2: Name the compound
Disilicon nonachloride.

#### Part c
# Explanation:
## Step1: Identify elements and subscripts
$ NF $: N is nitrogen, F is fluorine. Subscripts: 1 each (mono- for first element if 1, but mono- is often omitted for first element; for second element, mono- is used? Wait, no: molecular compounds: first element prefix (if >1), second element prefix (always). So $ NF $ is nitrogen monofluoride? Wait, no, actually, $ NF $ is not a common compound, but following rules: N (1, so no prefix), F (1, so mono-). But maybe a typo? If it's $ NF_3 $ it's nitrogen trifluoride, but here $ NF $: nitrogen monofluoride. But let's check: formula is $ NF $, so name: nitrogen monofluoride (or maybe the formula is incorrect, but as per given, $ NF $: nitrogen (1) and fluorine (1), so nitrogen monofluoride.

### Problem 3
#### Part a
# Explanation:
## Step1: Identify acid type
$ H_3P $: Binary acid (H and nonmetal P). Binary acids use "hydro-" prefix, root of nonmetal, "-ic" suffix.
## Step2: Name the acid
Phosphorus root is "phosphor-", so hydrophosphoric acid? Wait, $ H_3P $ is phosphine (a gas), but as an acid (in aqueous solution, $ H_3P $ is hydrophosphoric acid? Wait, actually, $ H_3P $ (phosphine) is not a common acid, but if we consider it as an acid (though it's a weak base), but the handwritten says "Hydro Phosphoric" – maybe intended as hydrophosphoric acid. But correct: for binary acid $ HX $ (X is nonmetal), name is hydro-X-ic acid. So $ H_3P $: hydrophosphoric acid (the handwritten has a spelling error, should be "hydrophosphoric acid").

#### Part b
# Explanation:
## Step1: Identify acid type
$ H_2SO_4 $: Oxyacid (contains H, S, O). The anion is $ SO_4^{2-} $ (sulfate). Oxyacids: -ate anion becomes -ic acid.
## Step2: Name the acid
Sulfuric acid (since sulfate is $ SO_4^{2-} $, so sulfuric acid).

#### Part c
# Explanation:
## Step1: Identify acid type
$ H_2CO_3 $: Oxyacid, anion is $ CO_3^{2-} $ (carbonate). -ate anion becomes -ic acid.
## Step2: Name the acid
Carbonic acid.

### Problem 4
#### Part a
# Explanation:
## Step1: Identify acid type
Chlorous acid: chlorous refers to $ ClO_2^- $ (chlorite ion). Oxyacid: formula is $ HClO_2 $ (since chlorite is $ ClO_2^- $, so $ H^+ + ClO_2^-
ightarrow HClO_2 $). The handwritten $ HClO_2 $ is correct.

#### Part b
# Explanation:
## Step1: Identify acid type
Carbonic acid: anion is $ CO_3^{2-} $ (carbonate). Oxyacid: formula is $ H_2CO_3 $ (since $ 2H^+ + CO_3^{2-}
ightarrow H_2CO_3 $). The handwritten $ H_2CO_3 $ is correct.

#### Part c
# Explanation:
## Step1: Identify acid type
Hydroiodic acid: Binary acid (H and I). Binary acid formula is $ HI $ (since hydroiodic acid is $ H^+ + I^-
ightarrow HI $). The handwritten $ HI $ is correct.

### Problem 5
#### Part a
# Explanation:
## Step1: Identify ions
Calcium (Ca) has charge +2, cyanide ($ CN^- $) has charge -1.
## Step2: Balance charges
To balance +2 and -1, need 2 $ CN^- $ for 1 $ Ca^{2+} $.
## Step3: Write formula
$ Ca(CN)_2 $.

#### Part b
# Explanation:
## Step1: Identify ions
Cesium (Cs) has charge +1, arsenate ($ AsO_4^{3-} $) has charge -3.
## Step2: Balance charges
To balance +1 and -3, need 3 $ Cs^+ $ for 1 $ AsO_4^{3-} $.
## Step3: Write formula
$ Cs_3AsO_4 $.

#### Part c
# Explanation:
## Step1: Identify ions
Chromium (III) has charge +3 ($ Cr^{3+} $), oxalate ($ C_2O_4^{2-} $) has charge -2.
## Step2: Balance charges
Find least common multiple of 3 and 2, which is 6. So 2 $ Cr^{3+} $ (total +6) and 3 $ C_2O_4^{2-} $ (total -6).
## Step3: Write formula
$ Cr_2(C_2O_4)_3 $ (the handwritten has a typo, should be $ Cr_2(C_2O_4)_3 $ not $ Cr_2(C_2O)_3 $; oxalate is $ C_2O_4^{2-} $).

### Problem 6
#### Part a
# Explanation:
## Step1: Identify ions
$ ZnI_2 $: Zn is zinc (charge +2, since $ I^- $ is -1, 2 $ I^- $ gives -2, so Zn is +2), iodide ($ I^- $).
## Step2: Name the compound
Zinc iodide (since zinc has only one common charge, no Roman numeral needed).

#### Part b
# Explanation:
## Step1: Identify ions
$ Sn(SO_3)_2 $: Sn is tin, sulfite ($ SO_3^{2-} $) has charge -2, 2 $ SO_3^{2-} $ gives -4, so Sn has charge +4 (tin(IV)).
## Step2: Name the compound
Tin(IV) sulfite.

#### Part c
# Explanation:
## Step1: Identify ions
$ CaC_2O_4 $: Calcium (Ca) has charge +2, oxalate ($ C_2O_4^{2-} $) has charge -2.
## Step2: Name the compound
Calcium oxalate (calcium has +2, oxalate -2, 1:1 ratio, so calcium oxalate).
