1) A mixture of anhydrous sodium carbonate and sodium hydrogencarbonate of mass 10.000 g was heated until it reached a constant
vodomira [7]

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;

2NaHCO_{3} (s) ----- > Na_{2} CO_{3} (s) + CO_{2} (g) + H_{2} O(g)

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

wel
  By  use   IUPAC  nomenclature   rule  compound  N2O3  is  named  as  

Dinitrogen  trioxide  (  answer  d)

Nitrogen (N2) is  named  before  oxygen(O3)  since    they  are  arranged  alphabetically.  In   addition  the  prefix  Di  is   used   infront  of  nitrogen  since    they  are  two  nitrogen  atoms   while  prefix  tri  is   used  infront  of  oxide  since  they  are 3   oxygen   atoms
