Sno2 + 2h2 → sn + 2h2o tin oxide reacts with hydrogen to produce tin and water. how many moles of sno2 are needed to produce 500.0 grams of sn? a. 1.57 b. 4.21 c. 634.8 d. 59,350

- B: 4.21 is the correct option.

Solution:- The given balanced equation is:

From the balanced equation, there is 1:1 mol ratio between and Sn.

To calculate the moles of required to produce500.0 grams of Sn, we need to convert the grams to moles and multiply it by the mole ratio as:

=

So, the correct option is B: 4.21 moles.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
