Sulfur carbon (SC) is not a commonly recognized chemical species, but if referring to the combination of sulfur (S) and carbon (C), it can be considered a compound when they chemically bond to form a new substance. However, as individual elements, sulfur and carbon are not molecules on their own; molecules specifically refer to groups of two or more atoms bonded together. In summary, SC would be a compound if it forms a stable chemical bond between sulfur and carbon.
The compound C2S2H4, also known as dithiolene or thioethene, is theoretically plausible, as it follows the basic valence rules of carbon, sulfur, and hydrogen. Carbon typically forms four bonds, sulfur can form two, and hydrogen forms one. However, the stability of such a compound would depend on steric and electronic factors, and it may not be commonly encountered or easily synthesized. Experimental confirmation would be needed to determine its existence and stability.
No, magnesium and sulfur would not form an ionic compound because they are both nonmetals. Ionic compounds are formed between a metal and a nonmetal. Magnesium and sulfur would likely form a covalent compound instead.
The empirical formula for a compound with 40% sulfur and 60% oxygen by weight would be SO3 (sulfur trioxide). This is because the ratio of sulfur to oxygen is 1:3 in this compound.
No, iodine and sulfur would not typically form an ionic compound. Both iodine and sulfur are nonmetals and tend to form covalent compounds when they react with each other.
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
Sulfur dioxide.
If this compound exists, it would be named "sulfur heptachloride".
The percentage by mass of sulfur in the compound is 16.97%. This was calculated by dividing the mass of sulfur (12.90g) by the total mass of the compound (76.00g) and then multiplying by 100 to get the percentage.
To determine the amount of sulfur present in 27.5 grams of carbon disulfide, we need to consider the molar mass of the compound. The molar mass of carbon disulfide (CS2) is 76.142 g/mol. From the chemical formula, one molecule of CS2 contains 2 sulfur atoms. As there are 32.065 grams of sulfur in each mole of CS2, you would calculate the grams of sulfur in 27.5 grams of CS2 using stoichiometry.
Sulfur is an element and therefore a homogeneous substance.
A compound of iron and sulfur is called ferric sulfide. But you would have to be pretty smart to do that.
