Difference between sodium chloride and sodium hydroxide?
Sodium chloride is NaCl. Sodium hypochlorite is NaClO.
Calcuate the mass of sodium chloride produced if 12.3 g of sodium oxide reacts with an excess of calcium chloride?
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
What shape do you think smaller pieces chipped from a large crystal of sodium chloride will have?
They will have the same structure as they are each the same compound. The ionic lattice will not change from one to the next.
How many atoms in 7.5g of sodium chloride?
To find the number of atoms in 7.5g of sodium chloride, you would first calculate the number of moles using the molar mass of NaCl (58.44 g/mol). Next, you would use Avogadro's number (6.022 x 10^23) to convert moles to atoms. The final calculation would yield the number of atoms in 7.5g of sodium chloride.
How do you separate sodium chloride and lead sulphate?
To separate sodium chloride and lead sulfate, you can use a process called precipitation. First, dissolve the mixture in water to form a solution. Next, add a reagent like hydrochloric acid, which will react with the lead sulfate to form a solid precipitate. The sodium chloride will remain in solution. Finally, filter the mixture to separate the solid lead sulfate from the liquid sodium chloride solution.
What happens when butanol reacts with sodium?
2 CH3CH2CH2CH2OH + 2 Na → 2 CH3CH2CH2CH2ONa + H2 Sodium butoxide is created next to hydrogen gas. It goes only in absolute absence of water, so no hydroxide ions are emitted in solution.
What are the steps for the Leblanc process?
The Leblanc process is a method for producing soda ash (sodium carbonate) that involves several key steps. First, sodium chloride (table salt) is reacted with sulfuric acid to produce sodium bisulfate and hydrochloric acid. Next, the sodium bisulfate is heated with limestone (calcium carbonate) to produce sodium carbonate, calcium sulfide, and carbon dioxide. Finally, the sodium carbonate is purified through crystallization and can be used in various applications.
What is the concentration of a solution with a volume of 0.50 L that contains 40.0 grams of sodium hydroxide?
To find the concentration, we need to calculate the molarity (M) of the solution. First, calculate the molar mass of sodium hydroxide (NaOH) which is 40.00 g/mol. Next, divide the mass of NaOH by its molar mass to get moles. Finally, divide moles by the volume in liters (0.50 L) to find the concentration in moles per liter.
How many grams of sodium sulfide are formed if 1.90 of hydrogen sulfide is bubbled into a solution containing 2.53 of sodium hydroxide assuming that the sodium sulfide is made in 91.0 yield?
The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.
What melts road ice?
Potassium Chloride is the most commonly used "salt", but Calcium chloride is next in line.

How do you prepare 0.25N of sodium hydroxide?
Well, honey, to prepare 0.25N sodium hydroxide, you simply need to dissolve 4 grams of sodium hydroxide pellets in enough water to make 1 liter of solution. Make sure to wear your safety goggles and gloves, we don't want any accidents in the kitchen! Just mix it up real good and you'll have your solution ready to go.
