To know the answer, you either know what is really the
nature and chemistry of a sugar solution. You can also know the answer by
knowing the meaning of entropy. Entropy is often interpreted as the degree of
disorder or randomness in the system. So the correct statement is that the
system becomes more disordered and has an increase in entropy.
The balanced chemical reaction would be:
KHC8H4O4<span> (aq) + </span>NaOH<span> (aq) → NaKC8H4O4 (aq) + H2O.
The concentration of the NaOH is equal 0.1 M. We use this and the volume given above to determine the mass of KH</span>C8H4O4. We do as follows:
0.1 mol / L NaOH (.015 L) ( 1 mol KHC8H4O4 / 1 mol NaOH) (204 g / 1 mol) = 0.306 g KHC8H4O4

Answer:
Almost 3 snicker's bar will contain the worth of energy stored in the battery which makes option A correct (Fewer than 5)
Explanation:
Step 1
The energy stored in a charged battery is 840 Watt- hours
Recall from the question that 1 KWh = 3600 KJ
So how many Kilo-joules will be in 840 Watt- hours?
I will convert 840 Watt- hours to KWh = 840 / 1000
= 0.840 KWh
Since I KWh gives 3600 KJ
then, 0.840 KWh will give x
x = 3024 KJ
3024 KJ of energy is stored in the battery
Step 2
A snicker bar contains 250 cal and 1 cal = 4.184 KJ
Convert 250 cal to KJ?
250 cal = 1046 KJ
Each snicker bar contains 1046 KJ
To calculate how many snicker's bar worth energy stored in the battery will be (y) ?
y = 3024 / 1046
y = 2.9 snicker's bar approximately 3
The correct option is Fewer than 5
