What two products are formed when iron sulphide is heated in air?
Solid iron oxide and a poisonous called sulphur dioxide
Why is a steaming iron called an iron?
Traditionally, irons were made of iron. They were heated by a fire and then applied to clothes. Today, irons are usually made of other metals.
You are given a small plotting compass and three grey metal bars one is aluminum one is iron one is magnet how can i identify each one?
The bar that affects the compass is the magnet, The bar that is attracted to the magnet is iron, and the bar that is not attracted to the magnet is aluminum.
How does iron react with steam when heated?
Fe is the chemical symbol for iron. When iron reacts with steam it corrodes, or rusts.
Why does rusty iron no longer conduct electricity?
Rusty iron no longer can conduct electricity because it is corroded, or it reacts chemically to form a compound that weakens it.
When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?
The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion
If a 150 gram iron bar is heated to 250c a second iron bar with a mass or 300 grams is heated to 250c which bar has the most thermal energy?
i would say that the 150 gram bar because the thermal energy will be able to travel around the bar quicker
How does a bar of steel get shorter after it has cooled down?
The bar will contract (get shorter) as it cools down, and expand (get longer) as it is heated up.
Why there is no substance formed when sulfur and iron is heated?
no,iron sulphide is made up when sulphur and iron is heated.
What is an expansion of solid?
When a solid is heated its particles gain more energy and begin to vibrate more. The particles move further apart and the solid is thicker and longer. A classic experiment for this is often made in school classes using a T-Bar and holder. At first the T-Bar fits perfectly into the holder, the T-bar is heated and students can observe that the T-bar no longer fits in its holder.
After a mixture of iron and sulfur are heated and then cooled a magnet no longer attracts the iron How would you classify the resulting material?
A chemical reaction has ocurred her and it has now formed a compund.
Is an iron bar an insulator or a conductor?
A iron bar is a conductor
Is a iron bar a insulator or a conductor?
A iron bar is a conductor
Is an iron bar a conductor or an insulator?
A iron bar is a conductor
What happens to iron filings and sulfur powder when heated?
When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
What happen to the hole of iron when heated?
oxides of iron are formed
