Question
In a lab, strontium (Sr) and oxygen (O2) are combined to produce strontium oxide (Sro). After balancing this reaction,
determine how many grams of strontium oxide are produced by the complete reaction of 19.6 grams of strontium.
Express your answer to the correct number of significant figures.

the answer is true.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

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.
