PLEASE HELP!! ASAP WILL GIVE BRAILIST (please explain how you got there or show a picture of work) a) Write the word equation for the reaction of silver chlorate reacts with sodium phosphate to produce silver phosphate and sodium chlorate.
b) Write the balanced formula equation for this reaction.
c) If 287 g of silver chlorate reacts with 52.8 g of sodium phosphate, what is the maximum number of grams mass of silver phosphate will be produced?
d) Identify which reactant is the limiting reactant and which is the excess reactant.
e) How many grams of the excess reactant reacts and how many grams are left over?

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 !

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
