If an object has a density of 1.35 g/ml ,will it float or sink in water?

It wil sink in water.

Explanation:

The law of bouyancy states that objects with lower densitiy than the liquid they´re submerged in will float, and if the object has a density of 1.35 g/ml, it wil sink in water because the density of water is 1g/ml, so because of the law of bouyancy and because the object has a greater density than water, when submerged in water the object will sink.

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.
