Dimas [21]

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⁻

zavuch27 [327]

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 sulfur dioxide (so2) stack-gas concentration from fossil-fuel combustion is 12 ppmv. determine the stack-gas so2 concentrati
sergejj [24]

The concentration of SO_{2} in the stack gas = 12 ppmv

That means 12 L of  SO_{2} is present per 10^{6} L gas

The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,

PV = nRT

(1 atm) (V) = (1 mol)(0.08206\frac{L.atm}{mol.K}) (273 K)

V = 22.4 L

1 mol SO_{2} occupies 22.4 L

Moles of SO_{2} = 12 L *\frac{1 mol}{22.4 L} = 0.5357 mol SO_{2}

Mass of  SO_{2} =0.5357 mol *\frac{64.06 g}{1 mol}  = 34.32 g SO_{2}  *\frac{10^{6} microgram}{1 g} =3.432 *10^{7}μg

Converting 10^{6} L to m^{3}:

10^{6} L *\frac{1 m^{3}}{1000 L} = 10^{3}   m^{3}

Calculating the concentration in μg/m^{3}:

\frac{3.432 * 10^{7} microgram}{10^{3} L}    = 3.432 * 10^{4}  microgram/m^{3}
