Trixie Bell is a yearling goat. She consumes 0.75 lb of grain and 4.25 lbs of hay daily. 14% of the grain is digestible protein, but only 2.5% of the hay is digestible protein.
How many grams of protein does Trixie Bell consume daily?

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

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 !

you gotta add the following molecules so we can give u an answer
