Question

this may not be math but please help


When Sonia added a certain powder to water, she noticed that the water fizzed and bubbled. She knew that this meant a chemical reaction was taking place. What were the reactants in this reaction?

the water and the powder
the powder and Sonia’s hand
the water and the bubbles
the powder, the water, and the gas they produced

Answer 1

Now think about it, what is the meaning of reactant

Answer 2

Answer 4

A reactant is a substance that takes part in and undergoes change during a reaction.

Answer 5

so is the answer A

Answer 6

We can cross out B. Because her hand did not change

Answer 7

Let's look at the other choices to make sure!

Answer 8

we can cross out C because that's what happened last

Answer 9

It can't be C. Since the bubbles are not in the problem. It said the water bubbled but the bubbles did not change

Answer 10

So I think it is either A or D which one do you think?

Answer 11

its D because that's like the definition and that's what happen

Answer 12

Well let's think about it on D it talks about gases, right? In the question it is only looking for the things that changed (reactants).

Answer 13

oh and the gass did not change so A
