Answer 1

Answer:

yes

Explanation:

Ratio of elements in carbondioxide is always same.

According to law of definite (fixed) proportion which is also known as law of constant composition;

              ' different samples of same compounds always contain it's component elements in a fixed ratio by mass and does not depend on its source andmethod of preparation'.

Answer 2

Hello

Do you need your answer?

Wait 2 minutes please

Ok sorry for being late

Are you listening me?

C + O2 --> CO2

NaHCO3 --> NaOH + CO2

Law of constant proportion!

Because in both the cases, CO2 is formed with same formula

So whatever is the source, both time same CO2 is formed
