Rate Of Reaction Questions & Answers

What did the test tube contain when the reaction had stopped? Copper (II) oxide is a black solid. It catalyses the decomposition of hydrogen peroxide. Some hydrogen peroxide was shaken with...
Correct answer is option D. A brown solid and colourless solution. A catalyst makes the reaction of hydrogen peroxide faster because the catalyst provides an alternative way. Copper (II) oxide is a catalyst that can speed up the decomposition reacti
What could explain this observation? When a piece of calcium metal is added to dilute hydrochloric acid, the reaction is seen to be faster after 60 seconds than after only 10 seconds.
The answer to this is D. Heat is always known to cause an effect on different things that it is applied to. Calcium metal is known to melt when it is exposed to hydrochloric acid more so of the hydrochloric acid has not been diluted prior to that. Th
