Consider the titration of a 20.0-mL sample of 0.105 M HC2H3O2 with 0.125 M NaOH. Determine each quantity. a. the initial pHb. the volume of added base required to reach the equivalence pointc. the pH at 5.0 mL of added based. the pH at one-half of the equivalence pointe. the pH at the equivalence pointf. the pH after adding 5.0 mL of base beyond the equivalence point

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

you need to give more information

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
