2naoh + h2so4 → 2 h,0 + na s04
how many grams of sodium sulfate will be formed if you start with 200 grams of sodium
hydroxide and you have an excess of sulfuric acid? i am having difficulties finding the grams.

200 grams of sodium  hydroxide produce 595 grams of sodium sulfate if we have an excess of sulphuric acid

Explanation:

2 NaOH + H2SO4 → 2 H20 + Na S04

From the above chemical equation we can state that

2 moles of sodium  hydroxide reacts with 1 mole of  sulfuric acid to produce 1 mole of sodium sulfate.

Now if we  start with 200 grams of sodium  hydroxide and you have an excess of sulfuric acid then the amount in grams of sodium sulfate will be formed

2 moles of sodium  hydroxide produce 1 mole of sodium sulfate.

In term of mass, we can say that

40 grams of sodium  hydroxide produce 119grams of sodium sulfate

1 grams of sodium  hydroxide produce (119/40) grams of sodium sulfate

then 200 grams of sodium  hydroxide produce ((119*200)/40) grams of sodium sulfate

or 200 grams of sodium  hydroxide produce 595 grams of sodium sulfate

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the answer is b & c i believe : )
