Pavlova-9 [17]

Answer: b. False

K+ ions move faster than the Na+ ions through the neuron membranes.

The concentration of Sodium ions outside the cell is very high. The concentration of Potassium ions inside the cells is very high. Leakage channels thus allow sodium ions to move inside the cells and pumps out the Potassium from the cells.

How many liters of Cl2 gas will you have if you are using 63 g of Na?
ELEN [110]

Answer:

You will have 19.9L of Cl2

Explanation:

We can solve this question using:

PV = nRT; V = nRT/P

<em>Where V is the volume of the gas</em>

<em>n the moles of Cl2</em>

<em>R is gas constant = 0.082atmL/molK</em>

<em>T is 273.15K assuming STP conditions</em>

<em>P is 1atm at STP</em>

The moles of 63g of Cl2 gas are -molar mass: 70.906g/mol:

63g * (1mol / 70.906g) = 0.8885 moles

Replacing:

V = 0.8885mol*0.082atmL/molK*273.15K/1atm

V = You will have 19.9L of Cl2
