One end of a copper rod it placed in a flame of a Bunsen burner. Small pieces of wax placed along with the rod melt at a progressively larger distance from the flame. Heat is transferred through the rod by

Explanation:

transfer of warmth by development of huge volumes of liquids ... One finish of a copper bar is set in a fire of a Bunsen burner. Little bits of wax put along the pole soften at continuously bigger separation from the fire. ... Warm air over the sea shore rises while cooler thick air from the sea surges in due to.

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 !
