Matte smelting is the most COMMON way of smelting COPPER–iron sulfur CONCENTRATES. The primary purpose of matte smelting is to turn the SULFIDE minerals in solid copper concentrate into three products: molten matte, molten slag, and offgas. ... Matte smelting oxidizes most of the iron and sulfur in its INPUT concentrates

I DONT KNOW SORRY EXPLANATION:sorry

I SUPPOSE that it WOULD be WATER

is utionPlease MARK me BRAINLIEST and FOLLOW me

The physical state of WATER at - 1. - 90 degree C will be Liquid2. - 0 degree C will be Solid3. - 100 degree C will be Gaseous 4. - 250 degree C will be also Gaseous because it is much higher than it's boiling pointThank you

gases are more COMPRESSIBLE than liquids EXPLANATION:As the inter PARTICLE SPACE is very largeand there force of attraction is less

Double-Replacement Reactions. A double-replacement REACTION is a reaction in which the positive and NEGATIVE ions of two ionic COMPOUNDS EXCHANGE places to form two new compounds. The GENERAL form of a double-replacement (also called double-displacement) reaction is: AB+CD→AD+BC.Explanation:please mark as branlist
