Answer:
Check the explanation
Explanation:
As we know the reaction of EDTA and 
+ and EDTA and 
+
Let us say that the ratio is 1:1
Therefore, the number of moles of + = molarity * volume
= 0.0400M * 0.011L
= 0.00044 moles
Therefore excess EDTA moles = 0.00044 moles
Given , initial moles of EDTA = 0.0430 M * 0.025 L
= 0.001075
Therefore reacting moles of EDTA with 
= 0.001075 - 0.00044 = 0.000675 moles
Let us say that the ratio between and EDTA is 1:1
Therefore moles of = 0.000675 moles
Molarity = moles / volume
= 0.000675 moles / 0.057 L
= 0.011 M (answer).
Answer:
Option A, C, D
Explanation:
A reversible adiabatic process is an isentropic process as entropy remains constant. Thus,
Entropy change (Delta S) = integral of (Q_rev)/T
Thus, option A and C are correct
For a reversible process, entropy generation is a positive quantity or zero. hence, statement B is not true
In an Adiabatic processes, entropy do not decrease. Hence, option D is also correct
100 degrees Celsius. And apparently this answer needs at least 20 characters to explain it well. But yes, the answer is 100 degrees Celsius
1) Hydrocarbon: CH3 - CH2 - CH2 - CH2 - CH3
2) Only single bonds => alkane => sufix ane
3) no substitutions
4) 5 carbons = > prefix penta.
Therefore, the name is pentane.
