The masses of the components are obtained as;
- Sodium hydrogen carbonate = 3.51 g
- Sodium carbonate = 8.708 g
<h3>What is decomposition?</h3>
The term decomposition has to do with the breakdown of the given substance into its components. The components of sodium hydrogen carbonate could be identified as water vapor, carbon dioxide gas and sodium carbonate. Among these products that have been listed here, we can see that it is only the sodium carbonate that remains as a solid. The others are gases that move away from the system that is under study.
Now putting down the equation of the reaction, we have;
Now, the loss in mass must be due to the carbon dioxide and the water. Hence we obtain the loss in mass to be 10.000 g - 8.708 g = 1.292 g
Mass of sodium hydrogen carbonate = 2 * 88 g/mol * 1.292 g/62 g/mol
= 3.51 g

The final temperature is 46.5°C.
<u>Explanation:</u>
As per the Charles law, the volume of a gas at constant pressure is directly proportional to the temperature which is measured in Kelvin.
So the equation for the Charles law is given as,
Now we have to find T2 as,
V1 = 736 ml = 0.736 L
T1 = 15 ° C
V2 = 2.28 L
Now plugin the values as,
T2 =
= 46.5°C
So as we see that as the volume increases, temperature also increased.
