Approximately 1667 cubical grains of NaCl would equal one millimeter, assuming each grain has a side length of 1 mm.
No, the reaction Br2 + NaCl → NaBr + Cl2 does not occur. The correct reaction between Br2 and NaCl is 2NaBr + Cl2.
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
To prepare a 5% NaCl solution, you will need 200 grams of NaCl for 4000 mL (4 L) of solution. This is calculated as 5% of 4000 mL, which equals 200 grams.
The chemical formula for table salt is NaCl, which stands for sodium chloride.
Solid NaCl is not an electrical conductor as the ions are held in a fixed lattice structure. Molten NaCl and aqueous solution NaCl are electrical conductors as the ions are free to move and carry charge, allowing for the conduction of electricity.
