Give a detailed account of steps of extracting pure copper from its ore

The extraction of pure copper from its ore involves several steps. Which can be broadly categorized into three main stages: concentration of the ore, extraction of copper, and purification of the extracted copper. Copper is metal, is primarily extracted from its sulfide ores, such as copper pyrite (CuFeSâ‚‚). 1. Concentration of the Ore 2. Extraction […]

What are alloys? How are they prepared? Name the alloy used for welding electric wires together.

What are Alloys? How are They Prepared? Alloy Used for Welding Electric Wires Together: Solder is used in electrical and electronic work to join components together by melting and then solidifying to form a strong electrical connection. Types of Welding Welding is a process used to join materials, typically metals or thermoplastics, by causing coalescence.

Why are metal sulfides and carbonates converted to oxides prior to reduction. Write the equation for the chemical reactions occurring during roasting and calcination of zinc ores.

Why Metal Sulphides and Carbonates are Converted to Oxides: Chemical Reactions: Calcination vs Roasting Calcination and roasting are two important thermal processes used in metallurgy to prepare ores for further extraction of metals. They involve heating ores, but they differ in their methods and objectives. Aspect Calcination Roasting Definition Heating of ores in the absence

Distinguish between metals and non-metals on the basis of chemical properties.

Metals and non-metals have distinct chemical properties that differentiate them. Here’s a clear comparison based on their chemical behavior: Metals vs. Non-Metals: Chemical Properties Property Metals Non-Metals Reactivity with Acids React with acids to produce hydrogen gas and a metal salt.Example Reaction:► Zn+2HCl→ZnCl2​+H2​ Generally do not react with acids; if they do, the reactions are

Why can highly reactive metals not obtained from their oxides using coke as a reducing agent?

Highly reactive metals, such as sodium, magnesium, and aluminum, cannot be obtained from their oxides using coke as a reducing agent because coke is not reactive enough to reduce these metals’ oxides. Here’s a simpler explanation: Reactivity of Metals and Reducing Agents: Why Coke Doesn’t Work for Highly Reactive Metals: Alternative Methods: Summary: Coke cannot

Name two metals which evolve hydrogen gas with dilute nitric acid with reaction

Two metals that evolve hydrogen gas when they react with dilute nitric acid are magnesium (Mg) and manganese (Mn). 1. Magnesium (Mg) with dilute nitric acid: 2. Manganese (Mn) with dilute nitric acid: These metals are able to reduce nitric acid under certain conditions, leading to the evolution of hydrogen gas. Hydrogen Gas Test: The

Why is hydrogen gas generally not evolved when metals react with dilute nitric acid.

Nitric acid is a strong oxidizing agent. When it reacts with metals, it typically oxidizes the hydrogen gas (Hâ‚‚) that would be produced into water (Hâ‚‚O). Instead of hydrogen gas being released, the metal usually reacts with nitric acid to produce a nitrogen oxide (like NOâ‚‚ or NO) along with a metal nitrate. Important points
