Answer:

An electrolytic cell uses electrical energy to drive a non-spontaneous redox reaction. An electrolytic cell is a kind of electrochemical cell. ... The electrolyte is usually a solution of water or other solvents in which ions are dissolved. Molten salts such as sodium chloride are also electrolytes.

Explanation:

An electrolytic cell has three component parts: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved. Molten salts such as sodium chloride are also electrolytes.

FrozenT [24]

Answer:

Explanation:

Catalyst is I2 . Because I2 is reacted with starting material in step 1 and generated in second step

Rate limiting step is step 1. Because in rate equation CH3CHO and I2 is mentioned. Hence the overall rate of reaction is depending CH3CHO and I2. Rate limiting step is step 1

How to first ionization energies vary within groups and across periods
trapecia [35]

Answer:

Ionisation energy increases along a period but decreases down a group

Explanation:

As you go along the period, the amount of protons in the nuclear increases. This causes nuclear attraction to increase meaning the attraction between the protons and the electrons is higher. This causes the electrons to be held more tightly to the nucleus meaning they are harder to remove. As well as that, the shielding stays the same along a period since the electrons are being added to the same shell, just different orbitals. Overall this makes it harder to remove an electron as you go along a period causing the ionisation energy to increase along a period.

On the other hand when you go down a group, the atomic radius increases. This is because the electrons are added to new shells which are further away from the nucleus, this also causes shielding to increase as there are more shells. This means the outer electrons being removed are held less tightly by the protons in the nucleus meaning they are easier to remove. This means that the ionisation energy decrease down a group.

A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 745 mmHg. Express this pressur
aleksklad [387]

Answer : The pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.

Explanation :

As we are given that the atmospheric pressure is, 745 mmHg.

Now we have to determine the pressure in torr and atm.

Conversions used:

1 atm = 760 mmHg

1 atm = 760 torr

1 mmHg = 1 torr

As, 760 mmHg = 1 atm

So, 745 mmHg = \frac{745mmHg}{760mmHg}\times 1atm=0.980atm

and,

As, 1 mmHg = 1 torr

So, 745 mmHg = 745 torr

Therefore, the pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
