Sometimes a fossil is formed as a result of the movement of an organism in soft sediment. What type of fossil is this called? bone fossil trace fossil frozen fossil petrified fossil

The most common method of fossilization is called permineralization, or petrification.

Trace Fossil

Explanation:

typically formed when an organism moves over the surface of soft sediment and leaves an impression of its movement behind.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
