Answer:
c. when the meniscus is between marks, estimate the reading to the nearest tenth of a division (ie, estimate to 0.01 mL if buret has 0.1 ml divisions)
Explanation:
When we put a liquid in a pipette, we can see that the surface of that liquid will have a curve. This curve is called the meniscus and it has the correct volume that an aqueous solution has. However, for this, it is necessary that the meniscus is observed at eye level and that its edges and center are clearly visible.

The rate of formation of water and the decomposition of hydrogen peroxide is double as compared to rate of formation of oxygen.
<h3>What is chemical reaction?</h3>
The chemical reaction is given as the reaction of the reactants in the process to form the new compound.
The chemical reaction with the decomposition of hydrogen peroxide is:
The rate of formation of water is given to be double the rate of formation of oxygen as 2 moles of water formed with 1 mole of oxygen.
The rate of disappearance of hydrogen peroxide is double with formation of oxygen as for decomposition of 2 moles of hydrogen peroxide, 1 mole of oxygen is formed.
