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.
Answer:
Number of neutrons: 44
Number of protons: 34
Number of electrons: 36
Explanation:
The atomic number of Se (Selenium) is 34
Mass number is 78
Number of neutrons = mass number - atomic number = 78 - 34 = 44
Number of protons is the same as the atomic number
Number of protons = 34
Selenium ion has a charge of -2. This means it accepts two more electrons
Number of electrons = atomic number + 2 = 34 + 2 = 36
Answer:
energy
Explanation:
The First Law of Thermodynamics (Conservation) states that energy is conserved, it cannot be created nor destroyed.
