By definition of what happens at the electrode surfaces, electrons always flow from the anode to the cathode in every electrochemical cell (voltaic and electrolytic).

<h3> What is Electrochemical Cell?</h3>

A device that produces electricity from a chemical reaction or that uses electrical energy to fuel a chemical reaction is known as an electrochemical cell. Voltaic or galvanic cells are electrochemical devices that produce electricity as a result of a spontaneous redox reaction. A voltaic cell can be compared to a battery. The type of cell known as an electrolytic cell needs an electrical supply to maintain the flow of electrons necessary to power the chemical reaction. The anode, cathode, and electrolyte are the three main elements of an electrochemical cell. A metal wire links the anode and cathode of a voltaic cell, which are divided into two half-cells. Ions can move between the two cells thanks to a salt bridge, completing the electrical circuit. Ions are produced by the electrolyte solution.

EleoNora [17]

Answer:

d.

Explanation:

H2 + Cl2 = 2HCL

From the equation 2g hydrogen combine with 71g of chlorine.

So 35.5 g Cl2 combines with 1g of H2

There are 100g of Cl2 so this will, by proportion, react with 100/35.5 g hydrogen.

This is 2.8 g hydrogen so the mass of HCl formed = 102.8 g.

14 Which property is a measure of the average kinetic energy of the particles in a sample or matter?
FrozenT [24]
(4) temperature is the correct answer.

Average kinetic energy is calculated by 3/2*R*T, in which R is a constant and is equal to 8.3145 J/ mol*K, and T is temperature measured in Kelvins.

Hope this helps~

Find any errors in the orbital notation diagrams below and correct them.
riadik2000 [5.3K]

Answer:

See explanation.

Explanation:

A. 2s is incorrect, the right arrow should be pointing downwards.

B. In 2p, the last box has 3 arrows. This is invalid. Each box can only store 2 arrows(electrons).  The last arrow should be moved to a 3p orbital (new box).

C. In this one, the arrows switched directions (left is down and right is up). You could fix each box or just the last one (in 3p) to point downwards.

Natalija [7]

Answer:

625=275

240=x

625x=275×240

625x=66000

x=66000/625

x=105 .6

Explanation:

If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625
