What else can I help you with?
How did the properties of the iron alone compare with the iron in the unheated iron-sulfur combination?
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
What mineral weights less than iron but doesn't rust. it is used to make ships?
That metal sounds a lot like aluminum.
Why doesnt zinc react with magnesium nitrate or iron chloride?
Zinc does not react with magnesium nitrate or iron chloride because zinc is less reactive than magnesium and iron. In a chemical reaction, a more reactive metal will displace a less reactive metal from its compound. Since zinc is lower in the reactivity series compared to magnesium and iron, it will not displace them from their salts.
Why magnesium is less dense then iron?
iron
Is the iron in food the same as the metal iron?
No, the iron in food is a mineral called iron that is essential for human nutrition. It is different from the metal iron used in construction and manufacturing, which is a chemical element with metallic properties.

Why are car parts made out of aluminium rather than iron?
Aluminium weighs less and it doesn't rust. It's about as hard as iron, too.
What are the different types of iron ores?
The main types of iron ores are hematite, magnetite, and siderite. Hematite is a reddish-black mineral and the most commonly mined iron ore. Magnetite is a dense black mineral that contains a high amount of iron. Siderite is an iron carbonate mineral that is less commonly extracted due to its lower iron content.
How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
What mineral such as iron or iodine that is needed in the diet in amounts less than 100 milligrams per day what type of element is it?
Trace minerals.
Why does same sized piece of wood is lighter than iron piece?
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
What weighs less a kilogram or gram?
A gram weighs less than a kilogram.
What mineral weights less than iron but doesn't rust. it is used to make ships?
That metal sounds a lot like aluminum.
Why would a parachute be smaller for a dog than a human?

Is jade a less valuable mineral than gold?
yes jade is an less valuable mineral than gold

How much does 700 cc weigh in pounds?
cc stands for cubic centimeter. It is a unit of volume equivalent to a milliliter. A pound is a unit of weight. A cc of water weighs less than a cc of, say, iron. So 700cc of water would weigh less than 700cc of iron would.
