HOW many elements are in this molecular FeCl3?
There are 4 elements in FeCl3: iron (Fe) and three chlorine atoms (Cl).
How many grams of FeCl3 does 5.88 X1028 weigh?
I don't have a good calculator, but i'll talk you through (will actually benefit you to do it yourself, this will come back to bite you if you don't learn it). Avagadros number is no. molecules per mole. 5.88x1028 / avagadros number gives your amount of moles. Moles / molecular weight gives weight
How many soluble chlorides are there?
There are many soluble chlorides, such as sodium chloride (table salt), potassium chloride, calcium chloride, and magnesium chloride. These compounds dissolve readily in water to form clear solutions.
How many chlorides of nitrogen?
There are four known chlorides of nitrogen: nitrogen trichloride (NCl₃), nitrogen dichloride (NCl₂), nitrogen monochloride (NCl), and nitrogen tetrachloride (NCl₄).
How many electrons does the iron have when it forms the ionic compound FeCl3?
In the ionic compound FeCl3, iron (Fe) forms an ion with a charge of +3 by losing 3 electrons. Chlorine (Cl) forms ions with a charge of -1. Therefore, the iron atom in FeCl3 has lost 3 electrons when forming the compound.

How many milliliters of 0.200 M FeCl3 are needed to react with an excess of Na2S to produce 2.75 g of Fe2S3 if the percent yield for the reaction is 65.0 percent?
.2M x V FeCl3=moles FeCl3 x 1mole Fe2S3/2mole FeCl3=moles of Fe2S3 x mm of Fe2S3/1 mole Fe2S3= g Fe2S3 x .65% yield. 2.75g Fe2S3/ .65= 4.23g Fe2S3/ 207.91= .02035 x 2mole FeCl3=.0407 moles FeCl3/ .2M FeCl3= .2035 L x 1000= 203.5 ml

What substance is present in FeCl3 that gives a purple color?
Quite many compounds. Phenols are one of the most common group of compounds here. In other words: any compounds containing benzene ring connected to OH group will give you purple color when treated with FeCl3. It seems that if you have FeCL3 sample it is probably impurified by phenolic compounds.
How many iron atoms are there in 5.33 moles of fecl3?
The formula shows that there is one atoms of iron in each formula unit of FeCl3, and by definition the number of molecules or formula units in a mole is Avogadro's Number. Therefore, 5.33 moles contains 5.33 X Avogadro's Number of atoms, which is 3.21 X 1024 atoms, to the justified number of significant digits.
Which of these are elementsatomscompoundsmixturesatoms and molecules fecl3 i2 cuo fes s and k many thanks?
fecl3 is a compound called iron chloride. i2 is an element called iodine. fes is a compound called iron sulphide. s and k are elements sulpher and potassium
How many milliliters of 0.200 M FeCl3 are needed to react with an excess of Na2S to produce 0.690 g of Fe2S3 if the percent yield for the reaction is 65.0 3 Na2S(aq) plus 2 FeCl3(aq) Fe2S3(s) plus?
To find the moles of Fe2S3 produced, convert 0.690 g to moles using the molar mass of Fe2S3. Then, use the stoichiometry of the reaction to determine the moles of FeCl3 required. Finally, use the molarity of FeCl3 to calculate the volume in milliliters needed, keeping in mind the percent yield.
What type of bonds do you use roman numerals when naming?
Roman numerals are commonly used in transition metals since they can have many possible ionization states. For example: Iron(III)Chloride would be FeCl3. Since iron is giving up 3 electrons, there must be three Chlorides since each chloride takes one electron each. Metal-Nonmetal bonds are always ionic (one element steals electrons from another).
What is the percent weight of 100 grams FECl3 and 900 mL of water?
Many people think that the gram is a measurement of volume. However, the gram is a measurement of weight, and so 100 grams weighs 100 grams or 3.52739619 ounces.Water weighs 8.34 (rounded to the nearest hundredth) pounds. 900 millilitres is equal to 0.237754846 US gallons. Therefore, 900 millilitres of water weighs about 1.98287542 pounds or 899.417161 grams.
