<h3>Answer:</h3>

Option-B (Halide; oxide) is the correct answer.

<h3>Explanation:</h3>

<em> Halides</em> are those substances which contains negatively charged halide ion i.e. X⁻.

Examples: F⁻ (Fluoride) , Cl⁻ (Chloride) , Br⁻ (Bromide) , I⁻ (Iodide) e.t.c.

<em>Oxides </em>are those substances which atleast containn one Oxygen atom.

Examples: FeO (Iron Oxide), Cr₂O₃ (Chromium Oxide)

<em>Silicates</em> are those anionic substances which contains silicon and oxygen with general formula [SiO. 4−x] n.

Examples: [SiO₄]⁻⁴ (Nasosilicate) , [Si₂O₇]⁻⁶ (Sorosilicates)

<em>Carbonates </em>are those substances which contains carbonate anion i.e. CO₃²⁻.

Examples: Na₂CO₃ (Sodium Carbonate) , MgCO₃ (Magnesium Carbonate)

<h3>Conclusion:</h3>

As in NaCaAlF, F⁻ is present hence, it is an Halide and the presence of O in FeCrO makes it Oxide.

If 45.0 mL of a 0.0500 M HNO3, 10.0 mL of a 0.0500 M KSCN, and 30.0 mL of a 0.0500 M Fe(NO3)3 are combined, what is the initial

Answer:

the initial concentration of SCN- in the mixture is 0.00588 M

Explanation:

The computation of the initial concentration of the SCN^- in the mixture is as follows:

As we know that

$KSCN \rightarrow K^ + SCN^-$

As it is mentioned in the question that KSCN is present 10 mL of 0.05 M

So, the total milimoles of SCN^- is

= 10 × 0.05

= 0.5 m moles

The total volume in mixture is

= 45 + 10 + 30

= 85 mL

Now the initial concentration of the SCN^- is

= 0.5 ÷ 85

= 0.00588 M

hence, the initial concentration of SCN- in the mixture is 0.00588 M
