Answer:
Explanation:
Among the most recent systems for the exploitation of geothermal energy, the most promising are the third generation ones, also called EGS (Enhanced Geothermal Systems). Their technology allows to dramatically improve energetic efficiency of both geothermal wells and dry rocks.

Answer:
a. NaHCO₃ + HCl → NaCl + H₂O + CO₂
b. 39.14 g is the mass of NaHCO₃ required to produce 20.5 moles of CO₂
Explanation:
A possible reaction for NaHCO₃ to make dioxide is this one, when it reacts with hydrochloric to produce the mentioned gas.
NaHCO₃ + HCl → NaCl + H₂O + CO₂
Ratio in this reaction is 1:1
So 1 mol of baking soda, produce 1 mol of CO₂
Let's calculate the moles
20.5 g CO₂ / 44 g/m = 0.466 moles
This moles of gas came from the same moles of salt.
Molar mass baking soda = 84 g/m
Molar mass . moles = mass
84 g/m . 0.466 moles = 39.14 g
3 to balance the calciums on both sides of the equation, but only if that balances the Cl on both sides of the equation to because you now have 6 Cl and 3Ca
