Question

When vinegar and baking soda react, the mixture becomes cold to the touch and a gas and a new liquid substance are formed.

Which best describes what is occurring in the reaction?

The reaction is chemical and endothermic.
The reaction is chemical and exothermic.
The reaction is non-chemical and endothermic.
The reaction is non-chemical and exothermic.

Answer 1

is it a?

Answer 2

What's your reasoning for (a)?

Answer 3

caus doesnt endothermic mean that its cold

Answer 4

and why chemical as opposed to non-chemical?

Answer 5

huh

Answer 6

there's an answer choice that says "non-chemical and endothermic" so I was just wondering why you chose "chemical and endothermic" instead

I'm not saying you're right/wrong just curious about your reasoning c:

Answer 7

bc i know that vinger and baking soda is a chemical recation i had 2 do a prdject on it

Answer 8

good, because the question says a new substance is formed, it's probably a chemical reaction

A is correct

Answer 9

yay tysm

Answer 10

As a side note - would you mind posting these in Chemistry rather than Computer Science? the Comp Sci question is for programming/technology related questions
