Answer:

An ionic compound whose aqueous solution conducts an electric current is called a(n) electrolyte

Explanation:

Electrolytes are substances that contain anions and cations and is therefore able to conduct the electric current.

For example: NaCl

NaCl → Na⁺ + Cl⁻

A sample of carbon dioxide gas has a density of g/L at a pressure of 0.889 atm and a temperature of 55.0 °C. Assume ideal behavi

gladu [14]

Answer:

163.5 °C

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 686 mL.

Initial temperature (T1) = 55 °C.

Final volume (V2) = 913 mL

Initial pressure (P1) = final pressure (P2) = 0.889 atm

Final temperature (T2) =.?

Next, we shall convert celsius temperature to Kelvin temperature.

This can be done as shown below:

Temperature (K) = Temperature (°C) + 273

T(K) = T (°C) + 273

Initial temperature (T1) = 55 °C.

Initial temperature (T1) = 55 °C + 273

Initial temperature (T1) = 328 K

Next, we shall determine the new temperature of the gas.

Since the pressure is constant, we shall determine the new temperature as follow:

V1/T1 = V2 /T2

Initial volume (V1) = 686 mL.

Final volume (V2) = 913 mL

Initial temperature (T1) = 328 K

Final temperature (T2) =.?

V1/T1 = V2 /T2

686/328 = 913/T2

Cross multiply

686 x T2 = 328 x 913

Divide both side by 686

T2 = (328 x 913)/686

T2 = 436.5 K

Finally, we shall convert Kelvin temperature to celsius temperature.

This can be done as shown below:

Temperature (°C) = Temperature (K) – 273

T (°C) = T(K) – 273

T(K) = 436.5 K

T (°C) = 436.5 – 273

T (°C) = 163.5 °C

Therefore, the temperature of the gas sample is 163.5 °C.

Gekata [30.6K]

Answer:

A. the temperature at which the motion of particles theoretically ceases.

Explanation:

Absolute zero is the same as 0 K (or zero Kelvin). At this point, the temperature cannot get any lower, and it is incredible difficult to get something to this low low temperature. The particles theoretically stop moving at 0 Kelvin aka absolute zero.

What is the molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate, Na2SO4?

Ymorist [56]

Answer:

The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7 $\frac{moles}{liter}$

Explanation:

Molarity is a concentration measure that indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

So, the Molarity of a solution is determined by the expression:

$Molarity (M)=\frac{number of moles of solute}{volume}$

Molarity is expressed in units ( $\frac{moles}{liter}$ ).

In this case:

number of moles= 0.0350

Volume=50 mL=0.05 L (1 L= 1,000 mL)

Replacing:

$Molarity=\frac{0.0350 moles}{0.05 L}$

Molarity= 0.7 $\frac{moles}{liter}$

The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7 $\frac{moles}{liter}$
