Answer:
Corona
Explanation:
The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.
2CuSO4 (aq) + 2H20 (1) -> 2Cu(s) + 2H2SO4(l) + O2(g)
A. CuSO4
B. Cu
C. H2SO4
D. H2
Cu will be produced at the negative electrode for the following reaction:
2CuSO4 (a q) + 2H20 (1) -> 2Cu(s) + 2H2SO4(l) + O2(g) ,therefore option (b) is correct.
Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a molten form.
Characteristics of negative electrode -:
The negative electrode in an electrolytic cell, is the one toward which positively charged particles are attracted.
The cathode has a negative charge because it is connected to the negatively charged .
When an electrolyte is dissolved in water and an electric current is passed through it, the Cations move towards the cathode and Anions move towards anode .
Cu will be produced at the negative electrode for the following reaction:
2CuSO4 (a q) + 2H20 (1) -> 2Cu(s) + 2H2SO4(l) + O2(g) ,hence option (b) is correct.

The H2 product will be produced at the negative electrode for the following reaction 2CuSO₄ (aq) + 2H₂0 (1) -> 2Cu(s) + 2H₂SO₄(l) + O₂(g). option D is correct.
The electrode is an electrical conductor or source of electricity that carries electric current or circuit to the non-metallic circuit parts of a circuit, some examples are electrolyte and semiconductor.
The following reaction 2CuSO₄ (aq) + 2H₂0 (1) -> 2Cu(s) + 2H₂SO₄(l) + O2(g) is a redox reaction in which the negative end is producing the H2 gas and copper gets solidify at the positive end.
Therefore, H₂ product will be produced at the negative electrode for the following reaction 2CuSO₄ (aq) + 2H₂0 (1) -> 2Cu(s) + 2H₂SO₄(l) + O₂(g). option D is correct.
