So ions are atoms that have either gained or lost electrons to complete their energy levels.
In order for a positive ion to be formed, an atom must lose electrons.
In order for a negative ion to be formed, an atom must gain electrons.
When an atom loses and electron, it loses a negative charge and then becomes a positive ion.
Answer:
52.0 moles
Explanation:
no. of moles of Zn =
The important part in this question is changing the kilograms to grams so that the units of the mass(grams) are divisible by the units of the molar mass (grams/molar mass)
Answer:
Yes, it's temperature dependent
Explanation:
A good fractional distillation depends largely upon maintaining a temperature gradient within the column. Perfectly, the temperature at the bottom of the column should be close or similar to the boiling temperature of the solution in the pot, and it should reduce continuously in the column until it reaches the boiling point of the more volatile component at the top of the column. If the distillation flask is heated too quickly, the whole column will heat up almost distributively and eliminate the desired temperature gradient. The result will be little fractionation and separation of the components.
The chloralkali or chlorine-alkali industry is an essential component of the chemical industry and generates sodium hydroxide and chlorine via the electrolysis of NaCl (table salt). The prime raw material is brine, that is, a saturated solution of NaCl, which is attained from the deposits of natural salt.
The products of this industry possess various essential uses like chlorine is used as a disinfectant, and is used to purify water, and for various other uses. Caustic soda or sodium hydroxide is also used for various applications like making cleaning agents and soap, making paper, purifying bauxite, and making rayon.
