Water extinguishers are common and inexpensive to maintain. Dry chemical extinguishers are more versatile and thus quite common, although more expensive, and they are not susceptible to damage from freezing temperatures.
Carbon Dioxide is the most common gas in fire extinguishers.
Water is the most common agent of erosion on Earth. It is responsible for shaping the landscape through processes such as river erosion, coastal erosion, and weathering.
Amoxicillin
no
The recommended method of extinguishing fires supported by most liquid or solid oxidizers is to deluge them with water. Metallic oxidizers are generally soluble in water. On dilution, there chemical reactivity is sharply reduced (Meyer, E. 2010 515).Meyer, E. (2010). Chemistry of hazardous materials (5th ed.). Upper Saddle River, NJ: Pearson Education Inc.

most can retire after 20 years.
While nitrogen is an inert gas and capable of putting fire out it is very impractical to use as a fire suppression agent. All products used in portable fire extinguishers can be seen when discharged either as a liquid or a powder so you can see where it is going. All of these products are also heavier than air so they will always tend to sink downward towards the base of the flames (at least for a short while). Nitrogen cannot be seen and is not heavier than air making it a very poor choice. please answer that can nitrogen is used as a fire extinguishing element, or tell me another elements for this purpose please answer that can nitrogen is used as a fire extinguishing element, or tell me another elements for this purpose
The National Firefighters Memorial in London bears 997 names of fallen wartime firefighters. Most of them presumably died in "the Blitz" (1940-1941).
answer is c . a class b fire extinguisher
No, quartz is not a common cementing agent for sandstone. Quartz is typically the primary mineral composing the sand grains in sandstone, while common cementing agents include calcite, silica, and iron oxide.
Arguably, gravity. But most educators would be more comfortable with the answer, "moving water".
