For the reaction
2 HCl + Na2CO3 → 2 NaCl + H2O + CO2 ,
8 L of CO2 is collected at STP. What is the
volume of 4.2 M HCl required?
1. 0.355 L
2. 0.085 L
3. 0.170 L
4. 1.12 L
5. 0.0425 L
6. 16.0 L

For the reaction
2 HCl + Na2CO3 → 2 NaCl + H2O + CO2
how much CO2 is produced at STP if 18.5 L
of 1.15 M Na2CO3 is used? The molar mass
of Na2CO3 is 106.01 g/mol.

Find the midpoint between the two points (10, -9) and (-16, -17).
