Sara and Juan conducted an experiment to test which soil would be BEST for growing plants. They used sand, silt, and clay. They also made a mixture of soil using equal parts of sand, silt, and clay. They planted bean seeds in four pots and placed the pots in the sunlight. They watered the pots every day and tracked the seed germination and plant growth. At the end of the experiment, the seed in the pot of silt grew fastest. Which conclusion can be drawn from the experiment?

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 !

u i forgot the answer?

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
