Answer:
MCO3 is BaCO3
The mass of CO2 produced is 0.28g of CO2
Explanation:
The first step in solving the question is to put down the balanced reaction equations as shown in the image attached. Secondly, we obtain the relative number of moles acid and base as mentioned in the question. The balanced neutralization reaction equation is used to obtain the number of moles of excess acid involved in the neutralization reaction.
This is then subtracted from the total number of moles acid to give the number of moles of acid that reacted with MCO3. From here, the molar mass of MCO3 and identity of M can be found. Hence the mass of CO2 produced is calculated as shown.
The answer is B- Low reactivity.
I think the correct answer from the choices listed above is option A. When you drink <span>milk of magnesia for an upset stomach, most likely, it would raise the pH in your body since it reacts with the acid inside reducing the amount of acid. Hope this answers the question.</span>
