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.
Asteroids lie within three regions of the solar system. Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 km) in diameter. Scientists estimate the asteroid belt also contains between 1.1 million and 1.9 million asteroids larger than three-fifths of a mile (1 km) in diameter and millions of smaller ones.
