Answer:
...BY CHOOSING A PROPER INDICATOR, SCIENTISTS CAN MINIMIZE THE DIFFERENCE IN THESE TWO NUMBERS,...
Explanation:
A chemical indicator is an agent or substance which gives a visible sign especially a color change when introduced to a solution of base indicating the threshold of the concentration of acid used in the titration procedure. These indicators include methyl orange, methyl red, phenolpthalein. They give a color change when the concentration of an acid as reached a critical limit in order for the reaction to be stopped. These indicators are involved in acid-base titrations, oxidation- reduction reactions and so on. More accurate results of the volume of the required acid or base is obtained by the introduction of these indicators.
Because they get new pieces of information from experiments
Li+(aq) +e- →Li (s) - 3.04
Cl2(g) + 2e- → 2Cl-(aq) +1.36
over all equation
2Li(s) + Cl2(g) →2 Li+(aq) + 2Cl-(aq)
The cell potential of this reaction is + 4.40 V
calculation
Ecell =E cathode - E anode
E cathode is = + 1.36 v
E anode is = - 3.04 V
therefore E cell= 1.36 -(-3.04 ) = 4.40 V
Answer:
yes because tissues take long to survive the aeedlings
