They represent 150 and 3 as Roman numerals respectively
iii or III = 3
150 = CL (100+50 = 150)
CL stands for cover letters and seems to have no connection to the number 500. In roman nuerals the letters CL mean 150 and not 500. The two again having nothing to do with each other.
To express chlorine (Cl) as an integer, you can use its atomic number, which is 17. This indicates that a neutral chlorine atom has 17 protons in its nucleus. In terms of its most common ion, Cl⁻, it has gained one electron, but the integer representation remains the atomic number 17. Therefore, Cl can be represented as the integer 17.
The Roman numeral CLXXXIV represents the number 184.
Titanium (III) chloride has the formula TiCl3 and therefore contains three chloride ions per formula unit. The number of chloride ions in 0.5 mol is therefore (3/2) X Avogadro's Number or 9 X 1023, to the justified number of significant digits.
Co+3 Cl-1 <---- these are the ions and their charges Co+3 Cl-1 Cl-1 Cl-1 <---- the charges have to add up to zero, so three -1 chlorine ions cancel out one +3 cobalt ion CoCl3 <---- simplify
The atomic number of chlorine (Cl) is 17. When two chlorine atoms (Cl) combine to form Cl₂, the atomic number remains 17 because it represents the number of protons in the nucleus of each chlorine atom.
The oxidation number of Cl in NaOCl is +1. This is because Na has an oxidation number of +1 and O has an oxidation number of -2, so the oxidation number of Cl must be +1 in order for the overall charge of NaOCl to be neutral.
The oxidation number of Cl in PtCl4^2- is -1. This can be determined by considering that the overall charge of the complex ion is 2-, and each Cl atom has an oxidation number of -1.
The Sulfide ion, S2-, is isoelectronic with Cl-
The oxidation number of Cl in Cl4 is -1. Since there are four Cl atoms, the total charge contributed by Cl is -4, making the oxidation number of each Cl atom -1.
The oxidation number of Cl in NCl3 is -1. Nitrogen typically has an oxidation number of -3 in nitrogen-containing compounds, so the overall charge of NCl3 must be 0, making the oxidation number of Cl -1.
iii or III = 3
The oxidation number for Cl in Cl4 is -1. Since Cl is a halogen, it typically has an oxidation number of -1 when it forms compounds.
In OCl (hypochlorite), the oxidation number of Cl is -1. This is because oxygen has an oxidation number of -2 and the overall charge of the OCl ion is -1, meaning that Cl must have an oxidation number of -1 to balance the charge.
