What does it mean that the Curiosity Rover found manganese oxide on Mars? The mineral manganese only oxidizes under specific conditions, one of which is with the help of microbes.
Museum of Science, Boston. . What does it mean that the Curiosity Rover found manganese oxide on Mars? The mineral manganese only oxidizes under specific conditions, one of which is with the help of microbes. While this doesn’t mean these same microbes are present on Mars, it is another clue towards potentially finding past life on the red ...

SOLVED:A common demonstration in chemistry courses involves adding a tiny speck of manganese(IV) oxide to a concentrated hydrogen peroxide (H2 O2) solution. Hydrogen peroxide decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). Manganese(IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. Write the balanced equation for the decomposition reaction of hydrogen peroxide.

When an oxide of manganese A is fused with 𝐾𝑂𝐻 in the presence of an oxidising agent and dissolved in water, it gives a dark green solution of compound B. Compound B disproportionate in neutral or acidic solution to give purple compound C. An alkaline solution of compound C oxidises potassium iodide solution to a compound D and compound A is also formed. Identify compounds A to D and explain the reactions involved.

Chemistry Explained 🧪 on Instagram: "When sulfuric acid (H₂SO₄) reacts with potassium permanganate (KMnO₄), it forms potassium bisulfate (KHSO₄) and permanganic acid (HMnO₄). Permanganic acid then breaks down into manganese(VII) oxide (Mn₂O₇) and water. • • • #chemistry #science #physics #biology #texas #chemistrymemes #lab #organicchemistry #education #chemistrylab #scientist #laboratory #chemist #sciencememes #chemistrylove #memes #chemistrynotes #losangeles #research #engineering #biochemist
