You used a graduated cylinder and a volumetric pipette to transfer 5 ml of a liquid sample into a small beaker. what exact volume did you measure? (hint: how many significant figures or decimal places do your measurements have for each type of glassware? was it 5.0 ml or 5.00 ml or else? ) is this information available on the glassware itself? if yes, where and what did you notice?

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

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.
