Considering that the precision of the meter stick leaves a potential error of approximately 1 mm in measuring individual heights, what percentage error in measuring the pressure difference pA − pB arises in using the piezometric method for the first manometer setting? What percentage errors in measuring pressure would arise if the bromoform or mercury methods were used instead for the same data? Are these errors tolerable?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
