When small pieces of manganese oxide were added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese oxide was not used up in the reaction. Which of the following is likely to increase the rate of the reaction? Reducing the number of pieces of manganese oxide used
Increasing the amount of solution
Using one cube of equal mass of manganese oxide
Chilling the hydrogen peroxide solution

In the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

Explanation:

It is known that more is the number of reactant molecules taking part in a chemical reaction more will be the number of collisions occur. As a result, more will be the rate of chemical reaction.

For example, When hydrogen peroxide dissociates into water and oxygen on addition of manganese oxide then increasing the number of reactants (hydrogen peroxide and manganese oxide) will also lead in the increase in rate of reaction.

Thus, we can conclude that in the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
