1.	In the following situation where the α of brass is 17 and copper is 19, can these two be used to construct a fire alarm?
Answer» Answer: Brass is an alloy of copper and ZINC, in proportions which can be varied to achieve varying mechanical and electrical properties.[1] It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another alloy CONTAINING copper, with tin in place of zinc;[2] both bronze and brass may include SMALL proportions of a range of other elements including arsenic, lead, phosphorus, aluminum, manganese, and silicon. The distinction between the two alloys is largely historical,[3] and MODERN practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy".[4]
