Question:

Why are copper fittings cleaned before soldering or brazing?

a. To remove oxidesb. To make it easier to see the junction between the fitting and the pipec. To enhance the aesthetic appearance of the completed jointd. To create enough clearance so that the pipe will fit into the fitting

Answer:

Molecurar weight Sb2S3 339.7 g/mol 800 Kg 800000 g 800000 g / 339.7 2355 moles Sb2S3 The ratio between Sb2S3 and Sb4O6 is 2 : 1 so we get 2355/2 1177.5 moles Sb4O6 The ratio between Sb4O6 and Sb is 1 : 4 1 : 4 1177.5 : x x 4700 moles Sb obtained moles InSb Molecular weight InSb 236.57 g/mol 4700 mol x 236.57 g/mol 1111879 g 1112 Kg We require for the reaction 4700 moles In 4700 mol x 114.82 g/mol 539654 g 539.6 Kg
yes they are officially face now
