Answer:
Electrolyte
Explanation:
A compound that conducts electricity when dissolved in water would most likely be classified as electrolyte.
The ionic compound in solid form do not conduct the electricity but when dissolve in water they separated into ions and have ability to conduct the electricity because of mobile ions that move freely and allow the charge to flow.
The ionic compounds are called electrolyte and electrolyte solution is formed when they dissolve in water.
For example when sodium chloride is placed into water it split into ions and conduct electricity because of mobile ions.
Chemical equation:
NaCl → Na⁺ + Cl⁻
Answer: react each with a dilute strong acid, such as sulfuric acid
the NaHCO3 will leave a clear solution (sodium ) after bubbling
NaHCO3 + H2SO4(aq)>>> CO2 (g) + H20 + Na2SO4 (in solution)
Calclum will leave a NOT clear liquid (Calcium)
Ca(HCO3)2 + H2SO4(aq)>>> CO2 (g) + H20 + CaSO4 (precipate)
The concentration of 
in the stack gas = 12 ppmv
That means 12 L of is present per 
The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,
V = 22.4 L
1 mol 
occupies 22.4 L
