What else can I help you with?
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?
PbSO4 is a compound made up of three elements: lead, sulfur and oxygen, chemically bonded together (= not mixed!).
Why is magnisium sulphate a compound?
It is a compound because it has two or more elements (in this case 3) chemically bonded together in a fixed ratio and structure. It is composed of the elements magnesium, sulfur, and oxygen.
What is the ratio of kinds of elements present in SO2?
In one molecule of sulfur dioxide, there is one sulfur atom and two oxygen atoms. This is simply a ratio of 1 sulfur atom : 2 oxygen atoms or 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 sulphate is a compound because it contains more than one element (three in this instance) in fixed ratios by mass to one another. There are at least two kinds of iron sulphate, those of iron(II) and iron(III). These have the same mass ratio between sulfur and oxygen, but the ratios of these two elements to iron are different in these two compounds.
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?
I think that it is probably magnesium sulphate.
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.
