What is Dalton molecular weight of phosphorus?
The molecular weight of phosphorus (P) according to Dalton's method is approximately 31 g/mol.
Does Kolbe formula represent a compound?
No, the Kolbe formula is a method of representing the structural formula of a chemical compound, particularly organic compounds that can be derived from other compounds through a series of substitution reactions. It is used to show the transformation of reactants into products during a chemical reaction.
How do you separate ammonium chloride from salt?
You can separate ammonium chloride from salt by sublimation. Ammonium chloride sublimes at a lower temperature compared to salt, so when heat is applied, ammonium chloride will turn directly into a gas and can be collected as a solid again by cooling it down. Salt will remain behind as a residue.
How do you separate ammonium chloride and sugar?
You can separate ammonium chloride and sugar by using a process called sublimation. Ammonium chloride can be sublimed, or turned from a solid into a gas without melting, by heating it gently until it vaporizes. The vapor can then be collected and allowed to cool back into solid form, leaving the sugar behind. This method works because sugar does not sublimate and will remain in its solid form.
How many moles of ammonium ions are in 8.754g of ammonium carbonate?
To calculate the number of moles of ammonium ions in 8.754g of ammonium carbonate, first find the molar mass of ammonium carbonate [(NH₄)₂CO₃] which is 96.09 g/mol. Next, find the moles of ammonium carbonate by dividing the given mass by the molar mass. There are 0.0913 moles of (NH₄)₂CO₃ in 8.754g. Since there are 2 ammonium ions in 1 molecule of ammonium carbonate, there are 0.1826 moles of ammonium ions in 8.754g of ammonium carbonate.
What is the molecular formula of ammonium sulphate by crcriss cross method?
The molecular formula of ammonium sulfate is (NH4)2SO4. This is derived using the criss-cross method, which involves crossing the numerical charges of the ions to determine the subscript for each element in the compound.
What are the two ways to prepare ammonium sulphate?
The two common ways to prepare ammonium sulphate are neutralizing ammonia gas with sulfuric acid or reacting ammonium hydroxide with sulfuric acid. In the first method, ammonia gas is bubbled through sulfuric acid to form ammonium sulphate. In the second method, ammonium hydroxide is slowly added to sulfuric acid to produce ammonium sulphate.
How do you Find formula for ammonium chloride using criss cross method?
To find the formula for ammonium chloride (NH4Cl) using the criss-cross method, you would cross the charges of the ammonium ion (NH4^+1) and the chloride ion (Cl^-1). The resulting formula will have one ammonium ion and one chloride ion, giving you NH4Cl.
What is the chemical formula of potassium sulphate in criss-cross method?
The chemical formula of potassium sulfate using the criss-cross method is K2SO4. This method involves swapping the numerical values of the charges on the ions to determine the subscripts in the compound.
What is the molecular formula for vineger?
The molecular formula for vinegar, which is primarily acetic acid, is C2H4O2.
How do you write the formula of ammonium carbonate by criss-cross method?
To write the formula of ammonium carbonate using the criss-cross method, you first write the symbols of the ions (NH4+) and (CO3^2-) side by side. Then, you criss-cross the numerical values from the charges of the ions to give you the formula NH42CO3.
What is meant by differential ammonium sulphate precipitation?
Differential ammonium sulfate precipitation is a technique used to purify proteins based on their solubility in ammonium sulfate at different concentrations. By gradually increasing the salt concentration, proteins with higher affinity for ammonium sulfate will precipitate at lower concentrations, allowing for selective recovery and purification of target proteins from a mixture. This method helps separate proteins by exploiting differences in their solubility characteristics.
Molecular formula for hypo solution?
Molecular formula of Hypo solution. & laboratory prepration method of the hypo solution?
What method could be used to separate a mixture of barium sulphate and ammonium chloride and lead chloride?
One method to separate a mixture of barium sulfate and ammonium chloride, and lead chloride would be to use precipitation. By adding a solution of sodium sulfate (Na2SO4), barium sulfate will precipitate out due to its low solubility. The remaining solution can then be filtered to separate the lead chloride from the ammonium chloride.
How the moleculer formula of a compound is calculated if its emperical formula is known?
To calculate the molecular formula from the empirical formula, you need to know the molar mass of the compound. Divide the molar mass of the molecular formula by the molar mass of the empirical formula to determine the factor by which the subscripts in the empirical formula should be multiplied to obtain the molecular formula.
Molecular formula of water using criss cross method?
The molecular formula of water is H2O. This means that each water molecule contains two hydrogen atoms and one oxygen atom. The criss cross method is typically used for ionic compounds to determine the ratio of ions in the compound.
Kjeldahl method for estimation of nitrogen in inorganic organic compound?
The Kjeldahl method is a widely used technique for determining the nitrogen content in organic compounds. It involves digesting the sample with concentrated sulfuric acid, which converts the nitrogen to ammonium sulfate. The ammonia is then distilled and collected in a solution of known acid, and the amount of nitrogen is determined by titration.
