What is the valency of sulphur in FeS2?
The S valence would be -1 when Fe(II) is 2+. In most cases sulfur has one negative and two possible positive valences: -2 and +4 or +6. So FeS2 is not a possible, or maybe a very rare, compound (Iron(II) persulfide?).
Why oxidation no of S in FeS2 is -1?
In FeS2 (iron disulfide or pyrite), the oxidation number of iron (Fe) is +2. Since the compound is electrically neutral, the sum of oxidation numbers must equal zero. Therefore, the oxidation number of sulfur (S) is calculated to be -1 to balance the charge of the iron ion.
What the answer for FeS2 plus O2 - and get Fe2O3 plus SO2?
The balanced chemical equation for the reaction FeS2 + 7/2 O2 → Fe2O3 + 4 SO2 is: 4 FeS2 + 11 O2 → 2 Fe2O3 + 8 SO2.
How do you know if something is real gold or iron pyrite?
1. If it looks like gold in bright sunlight, it will look shinny and like gold out of direct sunlight. Iron pyrite will not shine unless under direct sunlight.2. If you can put a knife blade on it and it bends, it is probably gold. Iron Pyrite will break.3. A pin will stick in gold, Iron Pryite will break.4. Some Iron Pyrite is magnetic.5. From what I have seen, if I am into Iron Pyrite, the pieces are usually consistant in size.
How much does pyrites cost per kilogram?
The cost of pyrite can vary depending on factors such as its quality, origin, and market demand. On average, pyrite can cost between $2 to $10 per kilogram. It is recommended to check with local suppliers or online sources for current pricing information.
What is the number of oxygen atoms in pyrite?
Pyrite's chemical formula is FeS2, meaning that it contains 1 atom of iron for every 2 atoms of sulfur. There is no oxygen in pyrite.
What is the atomic number of pyrite?
pyrite is a mineral consisting of 2 elements, so it doesn't have an atomic number. pyrite consists of iron and sulfur; FeS2 (Fe=1 Iron atom & S2= 2 Sulfur atom; these three atoms make a pyrite molecule). i this helped

What is the valency of sulfur in FeS2?
The valency of sulfur in FeS2 is -2. This is because the overall charge of FeS2 is zero, and iron has a positive valency of +2. Therefore, sulfur must have a valency of -2 to balance the charge.

What does ra stand for on the periodic table of element?
Ra stands for Radium. It is present in group-2.
What does the 'He' stand for in an alpha decay?
In any chemical reaction, including an alha decay, "He" stand for Helium, which is element #2. Helium is one of the Noble Gases. you will find it at the top right of the Periodic Table of the Elements.
When Pyrite can have a hardness of 6.5 on the mohs scale write 6.5 as a mixed number?
6.5=61/2
An element has 2 protons 2 electrons and 2 neutrons what is the element?
helium
How do you get the pyrite plate in battleon?
Go to *Alnaphar* and when she's done talking click on the rainbow you wil see a leprichaun. after that you need to battle around 20 monsters and after every 2 fights a bag of potions apear or twilly who heals you.. after those fights you get the choice to buy pyrite plate and quest further for golden plate. pyrite plate costs 100k gold
