6. This question relates to different gases.a. On a hot summer day, a lilo has been
filled with air at a pressure of 4 x 106 Pa and has a volume of 150dm3 on the shore where the
temperature is 35°C. What will the volume be when the lilo is placed in the sea at 18°C?
[.
s)b. Which would occupy more space at
stp - 4g of O2 or 4g of H2?
C. In the reaction of 15g of sodium carbonate with excess hydrochloric acid, what volume of carbon
dioxide would be produced at stp. The equation for this reaction is given below:
Na2CO3(6) + 2HC(aq) --> 2NACI(aq)+ H2Ou) +
