Chemical substance effervescent powders release when mixed with water?
carbon dioxide
What substance is formed when formed when lead oxide is mixed with carbon?
lead oxide + carbon-> lead + carbon dioxide
Is carbon homogeneous substance?
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
What is a substance that has no other substance mixed with it?
That is an element.
Why is a carbon atom a pure substance?
Biccarbonate is a oure substance because it is not part of a mixture, it is an ion. If you cannot break down a solution without the help of a chemical reaction (ex. Chromate CrO4 cannot be broken down further without a chemical reaction) then it is a pure substance.
Is carbon dioxide a mixed substance?
Carbon dioxide is a compound of two gases; Carbon and Oxygen. Therefore it is not a mixture, or mixed substance.
Chemical substance effervescent powders release when mixed with water?
carbon dioxide
What chemical substance do effervescent powders release when mixed with water?
CO2 - Carbon Dioxide
This occurs after smelting when 2 or more elements are mixed?
Ores
What element removes oxygen from iron oxide?
It's a process...But Smelting and CarbonIron ores consists of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, at high temperatures. Thus, the iron ore must be powdered and mixed with coke, to be burnt in the smelting process.However, it is not entirely as simple as that; carbon monoxide is the primary ingredient of chemically stripping oxygen from iron. Thus, the iron and carbon smelting must be kept at an oxygen deficient (reducing) state to promote burning of carbon to produce CO not CO2.
When baking soda is mixed with vinegar carbon dioxide bubbles are formed in this reaction carbon dioxide is?
a substance used in any processes
What substance is formed when formed when lead oxide is mixed with carbon?
lead oxide + carbon-> lead + carbon dioxide
How is iron extracted from rocks?
Iron ores consists mostly of oxygen and iron atoms bonded together into molecules. To convert these oxides or iron to metallic iron, they must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, and the process is done at high temperatures. The iron ore must be powdered and mixed with coke, which is essentially carbon, and the whole must be burnt in the smelting process.It is reduced with carbon by smelting. It is placed in a furnace with carbon coke and lime is added to reduce impurities
Is carbon heterogeneous or homogeneous?
heterogeneous
Is carbon homogeneous substance?
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
Is metal a compound element or mixture?
it depends. A lot of metals are elements like iron for example, these can be mixed to form alloys(compounds) steel for example is an aloy of carbon and iron. Metals exist as mixtures when they are found in their ores(mixed with other metals and minerals) and must be separated from their mixtures by smelting.
Why is a carbon atom a pure substance?
Biccarbonate is a oure substance because it is not part of a mixture, it is an ion. If you cannot break down a solution without the help of a chemical reaction (ex. Chromate CrO4 cannot be broken down further without a chemical reaction) then it is a pure substance.
