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 are made of rock and metal and broken away pieces of planets. They are grouped into three categories: Stony, Iron-Nickel, and a mixture of the two.Most asteroids that we know about fall into the first category, and are made of Silicates. A small percentage are Iron-Nickel.The rest form the third type. I believe that they are made of rocky bits left over from the formation of the inner planets. The run-of-the-mill asteroid is just one kilometer long.hey are grouped into three categories: Stony, Iron-Nickel, and a mixture of the two.
