Single-Replacement Reactions 1. Copper reacts with silver nitrate to form silver metal and copper(II) nitrate. copper metal + silver nitrate silver metal + copper(II) nitrate 2. Zinc metal reacts with hydrochloric acid to produce zinc chloride and hydrogen.
The first is by composition. The typical composition of an asteroid depends on its distance from the Sun. At the outer edges of the asteroid belt, that is between three and three and a half times further from the Sun than the Earth, over eighty percent of the asteroids are known as C-type.rom piles of 'rubble' to complex mixtures of metals, and carbon and silicon compounds, asteroids are not just dull grey lumps of cratered rock... We find that asteroids are fascinating objects, varying in composition and shape.
1 Some asteroids have moons of their own! 2  Most asteroids orbit the Sun in the Asteroid Belt, which lies between Mars and Jupiter. 3  Asteroids are also referred to as minor planets or planetoids.ost of them orbit the Sun between Mars and Jupiter, although there are groups of them that orbit closer. Asteroids come in three composition classes. C-types (chondrites) are made of clay and silicate rocks.
