## How do you make phosphorus sulfide?

Phosphorus sesquisulfide is prepared by treating red phosphorus with sulfur above 450 K followed by careful recrystallization with carbon disulfide and benzene. An alternative method involves the controlled fusion of white phosphorus with sulfur in an inert non-flammable solvent.

## How do you find the empirical formula?

Calculate the empirical formula.
1. In any empirical formula problem you must first find the mass % of the elements in the compound. …
2. Then change the % to grams. …
3. Next divide all the masses by their respective molar masses. …
4. Pick the smallest answer of moles and divide all figures by that.

## What is the empirical formula of the chloride?

Chloride/Formula
The chemical formula for an ionic compound such as KCl is always the same as its empirical formula. We can determine the empirical formula for potassium chloride by using the charges on the ions. Potassium ions have a 1+ charge and the formula K+ and chloride ions have a 1− charge and the formula Cl− .Feb 6 2016

## What is the empirical formula of hydrocarbon 79.9 mass Carbon?

Carbon = 79.9g hydrogen = 20.1g (work out the mass of each element) 79.9/12 = 6.66 20.1/1 = 20.1 (divide mass by atomic mass number) Ratio = 6.66 :… 1 = 1:3 (simplify to find lowest ratio) Therefore the simplest ratio and the empirical formula is CH3.

## What is empirical formula with example?

In chemistry the empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide or SO would simply be SO as is the empirical formula of disulfur dioxide S2O2.

## What is meant by empirical formula?

Definition of empirical formula

: a chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms in the molecule CH2O is the empirical formula for glucose.

## What is empirical formula in maths?

Hint: In this question we have to find the mode of given data using empirical formula. … Empirical formula states that [mode=3median-2mean]. This means we have to calculate mean and median of the given data and then use the formula to find mode.

## Is NaCl empirical?

Sodium Chloride is an ionic compound with the chemical formula NaCl. Since sodium chloride is not a molecule it has an empirical formula not a molecular formula. … The empirical formula of sodium chloride is (Na+Cl)n.

## How do you find the empirical formula of Aluminium chloride?

The calculation shows that for every 1 atom of aluminium there are 3 atoms of chlorine therefore the empirical formula is AlCl3.

## What is the empirical formula for a hydrocarbon containing 89.92% carbon by mass?

C9H

Explanation: 89.9%×120.0 gmol = 107.9 gmol C . Divide thru by the atomic mass of C 12.011gmol = 9 . Therefore the empirical formula is C9H? .

## What is a hydrocarbon formula?

Hydrocarbons are organic compounds that contain only carbon and hydrogen. … Those with double bond are called alkenes and have the general formula CnH2n (assuming non-cyclic structures). Those containing triple bonds are called alkynes and have general formula CnH2n2.

## What is the molecular formula of the following compound empirical formula NH2?

hydrazine

## What is meant when the symbol C 12 or 12c is used?

We represent isotopes by using the chemical symbol (“C” for carbon) and a number. The first carbon atom with only 6 neutrons would be called 12C or Carbon-12. The new one with 8 neutrons would be 14C or Carbon-14. Note that the number “14” is also the atomic mass number for this isotope.

## How is molecular formula related to empirical formula quizlet?

The empirical formula contains the smallest possible whole numbers that describe the atomic ratio. The molecular formula is the actual formula of a molecular compound.

## What is molecular formula?

A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. … The molecular formula for a compound can be the same as or a multiple of the compound’s empirical formula.

## Why is h20 an empirical formula?

For water the molecule is made up of two hydrogen atoms and one oxygen atom so its molecular formula is H2O. This also represents the simplest ratio of atoms in the molecule so its empirical formula is H2O.

## What is empirical formula for water?
