What else can I help you with?
Can you determine conclusively that an unknown substance contains magnetite by using only a magnet?
While a magnet can indicate the presence of magnetite due to its magnetic properties, it cannot conclusively determine its presence alone. Magnetite is ferromagnetic and will be attracted to a magnet, but other substances may also be magnetic. Additional tests, such as examining the substance's physical properties, conducting a chemical analysis, or using more specialized equipment, would be necessary for definitive identification.
Can you determine an unknown substance that contains magnetite by using only one magnet?
Yes, you can determine if an unknown substance contains magnetite by using a magnet. If the substance is attracted to the magnet, it suggests the presence of magnetite or other magnetic materials. However, this test alone will not quantify the amount of magnetite or differentiate it from other magnetic substances. Additional tests would be needed for a more definitive identification.
How do you determine whether a system is a subs or homogeneous mixt?
A mixture is homogeneous if its composition and properties are uniform throughout. A substance is a subset of mixtures, characterized by having uniform composition only. To determine if a system is a mixture or a substance, you would need to analyze its physical and chemical properties for uniformity.
Is a glass tube physical or chemical?
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
Do cockroaches have magnetite in there brains?
no they do not have magnetite in their brains it would make there heads too heavy to carry
Would a reaction with oxygen be a chemical or physical property?
A reaction with oxygen would generally be considered a chemical property because it involves a change in the chemical composition of the substances involved. Physical properties, on the other hand, do not involve changes in chemical composition.
Which mineral would react to iron filling's- magnetite or graphite?
Magnetite- it is naturally magnetic. Graphite is carbon- non magnetic
What is the chemical composition of N10 hydrochloric acid?
It would be 0.1M HCl solution. In 1 liter there would be 3.65 g of HCl and the balance would be water.
Is Pungent odor a physical or chemical change?
Pungent odor is a physical change because it only affects the sense of smell without altering the chemical composition of the substance emitting the odor.
What magnetite per gram?
The density of magnetite is approximately 5.2 grams per cubic centimeter. This means that one gram of magnetite would have a volume of approximately 0.192 cubic centimeters.
What is one thing that will happen in order to signify a chemical change?
If I understand your question correctly, it would be a change in composition that signifies a chemical change. Physical changes are only appearance, while a chemical change alters the substances' entire composition.
What property would be the most useful in telling hematite and magnetite apart?
The property that would be most useful in telling hematite and magnetite apart is magnetism. Magnetite is strongly magnetic, whereas hematite is not magnetic. This distinction can help differentiate between the two minerals.
