Why must coal be heated in the absence of air to change into coke?
Coal needs to be heated in the absence of air to turn into coke because oxygen in the air would react with the coal and burn it, preventing the transformation into coke. Heating the coal in the absence of air allows the volatile components to be driven off, leaving behind a more solid and pure carbon structure, which is coke.
What happens when coke is burnt in oxygen?
When coke is burnt in oxygen, it undergoes combustion to produce carbon dioxide gas and release energy in the form of heat. This is due to the oxidation of carbon in coke in the presence of oxygen.
Why is coke added to the iron ore in a bast furnace?
Coke is added to the iron ore in a blast furnace because it is used as a fuel to provide the high temperatures needed for the chemical reactions to occur. When coke is burned, it produces carbon monoxide, which acts as a reducing agent and helps to remove oxygen from the iron ore to produce molten iron.
What is formed if coke reacts with oxygen?
When coke reacts with oxygen, it undergoes combustion to produce carbon dioxide gas and release energy in the form of heat. This process is exothermic, meaning it releases more energy than it absorbs.
Why does coke act as reducing agent?
Coke is a reducing agent because it is a source of carbon which can donate electrons to other substances during a chemical reaction. The carbon in coke can react with oxygen or other compounds, reducing them by giving up electrons. This ability to donate electrons allows coke to act as a reducing agent in various chemical processes.
Why is oxygen blown through the molten iron?
to burn coke that will burn the raw material
What is the function of air in the blast furnace?
to burn coke that will burn the raw material

What is the function of coke in a blast furnace?
Coke is used in a blast furnace as a fuel and reducing agent. It provides the heat needed to melt iron ore and other materials to produce molten iron. Additionally, coke reacts with oxygen in the air to remove impurities from the iron ore, helping to create higher-quality molten iron.
How much exercise do you need to burn off 1 an of coke?
do 5 pushups and 10 jumping jacks because that together makes a coke.
Why is coke added to the iron ore in a bast furnace?

When coke is burned, it produces carbon monoxide, which acts as a reducing agent and helps to remove oxygen from the iron ore to produce molten iron.
What gas is given off when coke and oxygen mix?
Carbon Dioxide
What is carbon rate in blast furnace?
It is the quantity of carbon consumed by oxygen in unit time.for example coke consumed at tuyer level by hot blast which carry oxygen and this oxygen consume carbon in coke which consume in raceway per unit time.
What materials are needed to find out which soda has the most fizz?
diet coke.
What is formed if coke reacts with oxygen?
When coke reacts with oxygen, it undergoes combustion to produce carbon dioxide gas and release energy in the form of heat. This process is exothermic, meaning it releases more energy than it absorbs.
What is the independent variable of does a nail rust faster in coke or Pepsi?
The independent nariable of does a nail rust taster is coke or pepsi due to the presents of Oxygen
