(i) When solid mercury (II) oxide is heated, liquid mercury and oxygen gas are produced. (ii) Liquid hydrogen peroxide decomposes to form water and oxygen gas.
Answers
Answer:
1st. 2HgO ---> 2Hg + 02
2nd. 2H2 O2 ------> 2H2O + O2
Hope my answer helps you.
Answer:
(i) The melting point of mercury is -38.83 degrees Celsius, or -37.89 degrees Fahrenheit. Mercury can be solidified by cooling it to below its melting point. Another method to solidify mercury is by exposing it to high pressures above 14 kilo-bar.
Explanation:
(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Mercury(II) oxide is a red solid. When it is heated, it decomposes into mercury metal and oxygen gas. A reaction is also considered to be a decomposition reaction even when one or more of the products are still compounds
(ii)
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen
