Consider the titration of a 35.0-ml sample of 0.175 m hbr with 0.200 m koh. determine each quantity. a. the initial ph b. the volume of added base required to reach the equivalence point c. the ph at 10.0 ml of added base d. the ph at the equivalence point e. the ph after adding 5.0 ml of base beyond the equivalence point

answer: they produce more slow than unicellular organisms.

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.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
