The answer is the direct current may flow in a conductor such as a wire, but can also flow through semiconductors insulators or even through a vacuum as in electron or ion beams.

Answer:

Electric current.

Explanation:

Hello,

Electric current is defined to exist when there is a net flow of electric charge through a space, in this case the wire (circuits) or the conductor material. Remember that its SI units are the amperes (A) as well as it is measured using the ammeter

Best regards.

How many milliliters of a 25% (m/v) NaOH solution would contain 75 g of NaOH?

Luda [366]

Answer:

E 3.0 x 10² mL.

Explanation:

Hello there!

In this case, according to the formula for the calculation of the mass-volume percent:

$\% m/V=\frac{m_{solute}}{V_{solution}}*100\%$

Whereas it is necessary to know the mass of the solute and the volume of the solution. Thus, given the mass of NaOH as the solute, the volume of the solution would be:

$V_{solution}=\frac{m_{solute}}{\% m/V}*100\%$

Then, by plugging in we obtain:

$V_{solution}=\frac{75g}{25\%}*100\%\\\\V_{solution}=3.0x10^2mL$

Thus, the answer is E 3.0 x 10² mL.

Best regards!

A particular sample of pantothenic acid, a B vitamin, gives off 72.6 mL of nitrogen gas at 23 degrees c and 795 torr. What is th

disa [49]

Answer:

70.04 mL.

Explanation:

We can use the general law of ideal gas: V = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n is constant, and have two different values of V, P and T:

P₁V₁T₂ = P₂V₂T₁

P₁ = 795 torr, V₁ = 72.6 mL, T₁ = 23.0 °C + 273 = 296 K.

P₂ = 760 torr (standard pressure = 1 atm = 760 torr), V₂ = ??? mL,T₂ = 0.0 °C + 273 = 273 K (standard T).

∴ V₂ = P₁V₁T₂/P₂T₁ = (795 torr)(72.6 mL)(273 K)/(760 torr)(296 K) = 70.04 mL.
