Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
Is copper suphlate a mixture?
Copper Sulphate (check your spelling) is a chemical compound. It can only be separated by chemical change, not by physical change. Therefore, it is not a mixture.
Do you simplify empirical formula ratios?
Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
What is the exact meaning of Empirical formula?
The empirical formula represents the simplest whole number ratio of elements in a compound. It does not provide information about the actual number of atoms of each element present in the compound, only their relative proportions.
What is the chemical name for CdS?
The chemical name for CdS is cadmium sulfide. It is a compound composed of cadmium and sulfur elements in a 1:1 ratio.
Is copper sulphate mixture or compound?
Copper sulfate is a compound, not a mixture. It is composed of copper, sulfur, and oxygen elements chemically bonded in a fixed ratio.
Is lead sulphate an element or compound?
Lead sulphate is a compound, not an element. It is composed of the elements lead (Pb) and sulphur (S) in a specific ratio.
Why is magnisium sulphate a compound?
Magnesium sulfate is a compound because it is composed of two different elements, magnesium and sulfur, chemically combined in a fixed ratio. These elements bond together to form a compound with unique chemical and physical properties that differ from its constituent elements.
What is the ratio of kinds of elements present in SO2?
In sulfur dioxide (SO2), there is one sulfur atom and two oxygen atoms. Therefore, the ratio of sulfur to oxygen atoms in SO2 is 1:2.
Is pure copper sulphate a mixture?
No, pure copper sulfate is not a mixture. It is a compound composed of copper, sulfur, and oxygen atoms in a fixed ratio.
Why is iron sulphate a compound?
Iron sulfate is a compound because it is composed of two or more different elements (iron and sulfur) chemically bonded together in fixed proportions. The formula for iron sulfate is FeSO4, indicating the presence of both iron (Fe) and sulfur (S) atoms in a specific arrangement.
What is the ratio of aluminum ions to sulfur ions in the formula Al2S3?
The ratio of aluminum ions to sulfur ions in the formula Al2S3 is 2:3. This means that for every 2 aluminum ions, there are 3 sulfur ions present in the compound.
How many moles of sulfur are present in 3 moles of aluminum sulfate?
There are 6 moles of sulfur present in 3 moles of aluminum sulfate, because aluminum sulfate has a 2:3 ratio of aluminum to sulfur.
What do you get if magnesium reacts with sulphur?
When magnesium reacts with sulfur, magnesium sulfide is formed. Magnesium sulfide is a compound composed of magnesium and sulfur atoms in a 1:1 ratio, with the formula MgS.
Does a jar with sulfur and iron in it contain a compound?
A jar with sulfur and iron does not contain a compound, as compounds are made up of two or more different elements chemically combined in fixed ratios. Instead, the sulfur and iron would be considered a mixture of elements.
What is the ratio of the elements in the compound KI?
The compound KI consists of one potassium (K) atom for every one iodine (I) atom, so the ratio of potassium to iodine is 1:1.
What is the meaning of empirical formula?
Simplest atomic ratio of the elements present in the compounds.
