Answer: e. All voltaic (galvanic) cells involve the use of electricity to initiate nonspontaneous chemical reactions.
Explanation:
Electrochemical cell or galvanic cell or voltaic cell is a cell which converts chemical energy to electrical energy.
There are two electrodes in an electrochemical cell , where one is called as anode and one is called as cathode.
At cathode reduction takes place and at anode oxidation takes place.Thus the electrons generated at anode travel towards cathode and flow of electrons lead to generation of electricity.
Thus chemical reactions lead to generation of electricity.
Thus the statement that all voltaic cells involve the use of electricity to initiate nonspontaneous chemical reactions is false.

Explanation:
I HOPE IT HELPS :)
Molar mass NaOH = 39.997 g/mol
number of moles:
n = mass of solute / molar mass
n = 10.0 / 39.997
n = 0.2500 moles
Therefore:
Molarity = moles of solute / volume ( L )
M = 0.2500 / 2.0
M = 0.13 mol/L
Answer B
Answer:
What is the volume of gas at 2.00 atm and 200.0 K if its original volume was. 200.0 L at STP How many moles of nitrogen gas will occupy a volume of 150 L at STP? n=pr 11.00atm) What is the mass of 5.00 L of NO2 gas at STP? PV = nRT.
Explanation:
the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.
<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>
As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.
