When zinc rod is dipped in a solution of aqu copper sulphate copper is precipitated out?
When a zinc rod is dipped into a solution of copper sulfate, a redox reaction occurs where zinc metal reacts with the copper ions in the solution, displacing them to form copper metal. This is because zinc is higher in the reactivity series than copper, allowing it to displace copper in the solution and precipitate out as solid copper.
Do elements often swap neutrons and protons with other elements?
Elements do not typically swap neutrons and protons with other elements. Neutrons and protons are fundamental particles that make up the nucleus of an atom. Elements can undergo radioactive decay, where they may lose or gain protons and neutrons, but this usually results in the transformation of one element into another rather than a direct swap.
What if hydrogen sulfide reacts with carbon dioxide?
When hydrogen sulfide reacts with carbon dioxide in the presence of water, it forms carbon disulfide and water. The chemical equation for this reaction is: H2S + CO2 → CS2 + H2O. This reaction is typically carried out under specific conditions, such as high temperature and pressure, to promote the formation of carbon disulfide.
What happen when NaOH is added to the MgCl2 solution?
Well, when you mix NaOH with MgCl2, you get a fun little chemical reaction called a double displacement reaction. The sodium ions from NaOH swap places with the magnesium ions from MgCl2, forming magnesium hydroxide (Mg(OH)2) and sodium chloride (NaCl). It's like a chemistry party where everyone switches partners - just don't forget to balance your equation!
When homologous chromosomes swap pieces during meiosis this is called?
crossing over.
