Answer:

b) Product

c) Combustion

c) speeds up the rate of reaction

Explanation:

the substance produced by a chemical reaction is called a product (b)

Combustion (c) reactions are involving oxygen and "another substance" [and hydrocarbons] to <em>produce carbon dioxide and water</em>.

A <em>catalyst </em>acts to speed up the rate of a reaction (c)

<em>  > note </em><em>how it "speeds up" reaction: , it [a catalyst] lowers the pressure or temperature needed to start one--but it isn't used/consumed in the reaction</em>

So, the answers are: b, c, c

hope this helps!!

You see a worm crawling along the ground and wonder if scientists consider it living or nonliving. Which item below would not be
lisov135 [29]

Answer: a. A worm can move so it must be living.

Explanation:

If a worm is moving it is classified as a moving worm also known to be living if moving.

A worm could reproduce therefore it is living.

Worms do pass dirt into and through there bodies to eat of the minerals and discarding things through and let out.

If you do cut a worm in half it may damage it but since it has basically two heads on girl one boy and cut in half it may split them up, and make damage but they will eventually grow back if the injuries are not severe.

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. What was its acceleration?
Zigmanuir [339]

Acceleration is defined as velocity per unit time.

Acceleration=\frac{Velocity}{time}

a=\frac{dv}{dt}

Here, a=acceleartion,

v=velocity=36 m/s

t=time=12 s

a=\frac{dv}{dt}

a=\frac{36}{12}

a=3 ms⁻²

A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
