Answer:

loses electrons and loses potential energy.

Explanation:

A reducing agent looses electrons in an oxidation-reduction reaction. Oxidation is defined as the loss of electrons.

Reducing agents are oxidized in an oxidation-reduction reaction. When a specie looses electrons, it also looses energy. Hence the answer given above.

What is the amount of energy for a photon that has a 125 cm wavelength
Lera25 [3.4K]

Answer:

1.59 x 10⁻²⁵ J.

Explanation:

  • The energy of a photon is calculated Planck - Einstein's equation:

E = h ν , where

E is the energy of the photon,

h is  Planck's constant <em>(h = 6.626  x 10 ⁻³⁴ J.s)</em>

ν  is the frequency of the photon

  • There is a relation between the frequency (ν ) and wave length (λ).

λ.ν = c,

where c is the speed of light in vacuum (c = 3 .0 x 10 ⁸ m/s).

λ = 125 cm = 1.25 m.

<em>Now, E = h.c/λ.</em>

∴ E = h.c/λ = (6.626  x 10 ⁻³⁴ J.s) (3 .0 x 10 ⁸ m/s) / (1.25 m) = 1.59 x 10⁻²⁵ J.

(iii) Give two reasons why the electrolyte contains cryolite​
V125BC [204]

Answer:

The mixture of cryolite and aluminum oxide has a lower melting point than pure aluminum oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.

Hydrogen gas is produced when zinc reacts with hydrochloric acid. If the actual yield of this reaction is 85%?
Leokris [45]
Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂

One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles

The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles

mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g

The answer is D.
