Which statement best describes the use of a catalyst in a fuel cell?
A catalyst in a fuel cell speeds up the chemical reactions that convert fuel and oxygen into electricity, without being consumed in the process. It lowers the activation energy required for the reactions to occur, increasing the efficiency of the fuel cell.
What is the name of the process of the industrial preparation of ammonia?
The industrial process for preparing ammonia is called the Haber-Bosch process. It involves combining nitrogen and hydrogen under high pressure and temperature in the presence of an iron-based catalyst to produce ammonia.
How is phosgene made and what are the steps involved in its production process?
Phosgene is made by reacting carbon monoxide with chlorine gas in the presence of a catalyst. The production process involves passing the gases over a catalyst at high temperatures to form phosgene gas, which is then purified and collected for use in various industrial applications.
Is the catalyst consumed in the reaction process?
In a chemical reaction, a catalyst is not consumed and remains unchanged at the end of the reaction process.
How do you produce ammonia gas?
It can be manufactured using the Haber Process - see wikipedia for more details in the related link. This basically uses Hydrogen and Nitrogen with pressure, temperature and a catalyst. The reaction is N2 + 3H2 ----->2NH3
What are the Brief example of an industrial process that uses a catalyst?
buildings.
Which statement best describes the relationship between the industrial revolution and mass production in great Britain ?
Technology developed during the Industrial Revolution allowed for the mass production of goods such as textiles.
Which process is iron used as catalyst?
Iron is used as a catalyst in the Haber process, which is the industrial method for producing ammonia from nitrogen and hydrogen gases. The presence of iron catalyst helps to increase the rate of the reaction and improve the yield of ammonia.

What statement Correctly describes identification and authentication?
Identification is part of the authentication process.
Which statement describes a benefit of desalination technology?
The desalination process converts ocean water to freshwater.
What is the catalyst that initiates the process of transcription?
The catalyst that initiates the process of transcription is an enzyme called RNA polymerase.
How is phosgene made and what are the steps involved in its production process?

What statement correctly describes the iterative nature of the process groups?
- You repeat Monitoring & controlling process - you implement the initiating and closing process - you continue repeating planning and executing
Is the catalyst consumed in the reaction process?
In a chemical reaction, a catalyst is not consumed and remains unchanged at the end of the reaction process.
What statement best describes health promotion?
it is the process of enabling people to exercise more control over their health
