Answer:
(A) Mixture; physical; (B) compound; chemical; (C) mixture; physical
Explanation:
(A) Orange liquid
Mixture — Red solid dissolved in yellow liquid gives orange solution
Physical change — separated by distillation with no change to the substances
(B) Crystalline solid
Compound — decomposition converts a substance into two or more different substances with different properties.
Chemical change — new substances formed.
(C) Cup of tea
Mixture — sugar is dissolved in the tea
Physical change — the tea and sugar retain their original properties.
Answer:
Magnesia, or magnesium oxide, is a mineral composed of alkaline earth metals. The majority of today's magnesium oxide comes from calcining natural minerals.

Cs is formed at anode and Sr is formed at cathode.
<h3>What is Oxidation Half reaction ? </h3>
The half reaction of overall reaction in which reactant loses electrons during the reaction is called Oxidation Half Reaction.
<h3>What is reduction Half reaction ? </h3>
The half reaction of overall reaction in which reactants gains its electrons during the reaction is called Reduction half reaction.
At the cathode (-ve electrode), cations are reduced and At the cathode (-ve electrode), anions are oxidized.
Reduction: Sr⁺² + 2e⁻ → Sr
Oxidization: 2Br⁻ (l) → Br₂ (g) + 2e⁻
Thus from the above conclusion we can say that Cs is formed at anode and Sr is formed at cathode.
