Answer:
Electrolytic cell. Salt bridge.
Explanation:
Match the following terms to their correct definitions.
- A cell that requires energy to bring about a nonspontaneous redox reaction. Electrolytic cell. In an electrolytic cell, energy is provided from an outer source, such as a battery.
- An ion-containing conducting medium used to physically and chemically connect the two half-cells in an electrochemical cell. Salt bridge. The salt bridge contains a salt (strong electrolyte) and it is fundamental in a voltaic cell.
Chemical reaction: NaHCO₃ + HCl → NaCl + H₂CO₃.
H₂CO₃ → H₂O + CO₂.
If amount of sodium bicarbonate (NaHCO₃) is 1 mol, then from from reaction we can calculate amount of carbon dioxide:
n(NaHCO₃) . n(CO₂) = 1 : 1.
n(CO₂) = 1 mol.
At standard pressure and temperature:
V(CO₂) = n(CO₂) · Vm
V(CO₂) = 1 mol · 22,4 L/mol.
V(CO₂) = 22,4 L.
What are the equations.....
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Answer:observation
Explanation:
this is the answer because they saw it they know it is there. the flowers are pink and they saw that that’s what an observation is so the answer is an OBSERVATION
