The answer is: The arrows are made of wood and gold. The arrows are made of wood and hard, which can break things and make leather.
The ancient arrows are made of blue. For those who are made of green, the alloy is also made of green. When it is added to the alloy, the hardness of the alloy is greatly increased, and the melting rate is reduced, which is convenient for manufacturing. With the green arrows, the edge is good, and it can be used in the process, and the breaking is advanced.
When it comes to the production of the arrows, the arrows are also made. The hardness of the blade, especially the green one, can be formed into various shapes to meet different needs. Its strength, can penetrate deeply into the object, and the power is more than in the past.
The shape of the arrow is also studied. There are Mitsubishi, whose blade surface is angled, and the power of breaking armor is very high; there are flat ones, which are conducive to cutting; and there are those who are inverted, which are pierced one by one, to be pulled out, only to increase the damage.
Of course, the tool of the arrow is hard, and the effect of shooting and breaking. Its materials are green and green, and the shape is complex, all of which are developed in the same way, pursuing more power.

3 - The chemical properties of the shell are various?
Husband 3 - The shell is a chemical substance with diverse properties. Under normal conditions, it is quite stable and not easy to react violently with common things. However, when encountering strong acids and bases, it can show a lively state. Strong acids can destroy part of its structure, or cause it to decompose, generating new substances; when encountering strong bases, it can also cause specific chemical reactions to occur and change its chemical composition.
As for the 2-shell, its chemical properties are also very interesting. This shell contains calcium carbonate and other substances, so it is easy to react with it in an acidic environment. In case of weak acids such as acetic acid, it slowly dissolves and releases carbon dioxide gas. It looks like a bubble rising, which is quite wonderful. And 2 - The shell will decompose under high temperature conditions, and calcium carbonate will decompose into quicklime (calcium oxide) and carbon dioxide. This reaction is often used in industrial production of lime. And 2 - The surface of the shell is not smooth and has certain adsorption properties. It can absorb tiny particles and some ions in the surrounding environment. This property makes it useful in some environmental purification processes.
In short, the chemical properties of 3-direction and 2-shell have their own characteristics, and under different conditions, they exhibit different chemical behaviors, whether stable or active. They are all wonders of the chemical world, which can be deeply explored by us to understand and be used in many fields.
