Jack was playing with a toy car and a track that records velocity over time using sensors and it generated the graph below: At which points on the graph is the car showing acceleration?

Group of answer choices

Sections a, c, and d

Sections a, b, c, and d

Sections a and d

Section a only

a,c, and d

Explanation:

if velocity is not a flat line, that means there is acceleration, whether it is positive or negative acceleration.

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.

i believe the answer is three water molecules
