Industrial Processes

Question 1

most common way of producing alumina, the oxide of aluminum

Answer 1

Bayer Process

Question 2

process involves refining (removing impurities from) bauxite, an ore of aluminum, by soaking the bauxite in sodium hydroxide. this refined bauxite becomes alumnia, which is later smelted into aluminum

Answer 2

bayer process

Question 3

process typically involves four stages: digestion, clarification, precipitation, and calcination

Answer 3

bayer process

Question 4

process made in 1887 by Karl name

Answer 4

bayer process

Question 5

became the first worldwide way of mass-producing steel, and allow of iron

Answer 5

Bessemer process

Question 6

involves highly compressed, hot air being blown through molten iron, after which the oxygen in the air reacts with the impurities (which can include sulfur and manganese) in the molten iron. this causes impurities to burn out of the now purified metal

Answer 6

Bessemer process

Question 7

air flows through small holes called tuyeres

Answer 7

Bessemer process

Question 8

created in 1855 and 1857 by Henry name and William Kelly

Answer 8

Bessemer process

Question 9

this process is the industrial process used to produce sulfuric acid. it replaced the now defunct lead-chamber process

Answer 9

contact process

Question 10

in the past, the catalyst used in the process was platinum, but after it was discovered that platinum could lead to poisoning, a transition was made to a vanadium oxide catalyst

Answer 10

contact process

Question 11

other products of the process include sulfur trioxide and oleum

Answer 11

contact process

Question 12

created by peregrine Philips in 1831

Answer 12

contact process

Question 13

as its name suggests, the process involves making use of an electric current to decompose a chemical, whose parts form at both the anode and the cahode

Answer 13

electrolysis

Question 14

one of the most common applications of it is on water; that process breaks down water into oxygen and hydrogen gas

Answer 14

electrolysis

Question 15

british chemist Sir Humphrey Davy made use of it to discover barium, calcium, potassium, and sodium

Answer 15

electrolysis

Question 16

industrial process that carries out nitrogen fixation via the reaction of nitrogen and hydrogen. used to produce ammonia

Answer 16

Haber-Bosch Process

Question 17

the ammonia is produced form the one nitrogen atom and the three hydrogen atoms by means of an iron catalyst

Answer 17

Haber-Bosch Process

Question 18

one of the most common uses of the this process is the production of fertilizer

Answer 18

Haber-Bosch Process

Question 19

process invented in 1909 by Fritz name

Answer 19

Haber-Bosch Process

Question 20

the most common way of producing aluminum, unlike the Bayer process which produces alumina. it follows the bayer process in the steps to produce aluminum

Answer 20

hall- heroult process

Question 21

a typical procedure in this process is the use of a cryolite bath, in which alumina is dissolved. afterwards, an electric current is sent through the mixture of cryolite and alumina

Answer 21

hall-heroult process

Question 22

process made in 1886 by Charles Martin name and Paul name

Answer 22

hall-heroult process

Question 23

industrial process that is currently used to produce metallic titanium. it replaced the now defunct hunter process

Answer 23

kroll process

Question 24

titanium is produced from reducing titanium tetrachloride by using magnesium. the process makes use of fractional distillation to separate different substances

Answer 24

kroll process

Question 25

made in 1940 by will j. name

Answer 25

kroll process

Question 26

most common process to make nitric acid. it replaced the now defunct birdeland-eye arc process

Answer 26

Ostwald process

Question 27

oxidizes the ammonia produced from the haber process by using a catalyst that contains the element rhodium

Answer 27

Ostwald process

Question 28

aqua regia can be formed by using the Ostwald process because the aqua regia is comprised of nitric acid and hydrochloric acid

Answer 28

Ostwald process

Question 29

created in 1902 by William name

Answer 29

ostwald

Question 30

process that is used to purify silicon by reacting it with hydrochloric acid

Answer 30

siemens process

Question 31

reaction between the HCL and the silicon creates trichlorosilane; at high temperatures the trichlorosilane melts and yields silicon rods, which are in a purer form than the silicon the process started with

Answer 31

siemens process
