(ii) The Cu2+ ions are attracted to the negative electrode, where they are reduced to produce copper atoms.
allochka39001 [22]
Electrolyte for the electrolysis is copper(II) sulfate
CuSO₄ = Cu²⁺ + SO₄²⁻

the reaction at the negative electrode
(cathode -) Cu²⁺ + 2e⁻ = Cu⁰

and...
(anode +) 2H₂O - 4e⁻ = O₂ + 4H⁺

An inventor claims to have devised a closed cyclic engine which exchanges heat with cold and hot reservoirs at 25 and 350 ◦C, re
kati45 [8]

Explanation:

The given data is as follows.

T_{c} = 25^{o}C,  T_{h} = 350^{o}C

Work produced per kJ of heat extracted from hot reservoir = 0.45 kJ = Efficiency

If the device is Carnot cycle then its efficiency will be maximum and its value will be equal to [1 - (\frac{T_{c}}{T_{h}} )]

Using this relation we will calculate the efficiency as follows.

                 Efficiency = [1 - (\frac{T_{c}}{T_{h}} )]

                        = 1 - (\frac{25}{350})

                       = 0.928

Hence, it means that this type of device is possible and the claim is also believable.

We say that salts will dissociate but acids will react with water. We say that acids will
Paha777 [63]

Answer:

ionize

Explanation:

Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.

For example, in the chemical reaction;

HX + H20 -------> X- + H30+

HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.
