In Science Experiments. a more reactive metal displaces a less reactive metal because a more reactive metal has more affinity for other nonmetals than a comparitively less reactive protein. for exam â¦ ple, iron displaces copper from copper sulphate as it is more reactive than copper and hence it forms iron sulphate.
Pears have a core surrounded by flesh, meaning pears are pomes. A pome (pohm) is a fruit that has a core surrounded by fleshy tissue that we can eat. The core is usually not eaten. Berries are different - the seeds are inside the fleshy part, not separated from it by a core. Apples and pears are pomes. Drupe
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolan.Concrete containing silica fume can have very high strength and can be very durable.ilica fume is a byproduct of producing silicon metal or ferrosilicon alloys.
