I'm glad you asked
The prefix "iso" is used when all carbons except one form a continuous chain. ... The prefix "sec" or "s" is used when the functional group is bonded to a secondary carbon.
Answer:
D) Mg(s)
Explanation:
We are given:
The substance having highest positive 
potential will always get reduced and will undergo reduction reaction. Here, chlorine will undergo reduction reaction will get reduced. Magnesium will undergo oxidation reaction and will get oxidized.
<u>Reducing agents are the species which reduces others and oxidizes itself. Thus, Magnesium will be the strongest reducing agent.</u>

Answer:</h3>
12 years
<h3>
Explanation:</h3>
We are given;
Half life of hydrogen-3 is 12 years
Initial mass of Hydrogen-3 is 20 grams
Final mass will be 10 g because we are told half of the sample will decay.
To find the time taken for the decay we need to know what half life is;
- Half life is the time taken for a radioactive isotope to decay to half its original amount.
Remaining mass = Original mass × 0.5^n
n = number of half lives
therefore;
10 g = 20 g × 0.5^n
0.5 = 0.5^n
n = log 0.5 ÷ log 0.5
= 1
But, 1 half life is 12 years
Therefore, the time taken is 12 years
It's essentially another word for concentration, of the acid. e.g. "the molarity of the acid is 3moldm^-3"
Answer : The enthalpy change for the solution is 166.34 kJ/mol
Explanation :
First we have to calculate the enthalpy change of the reaction.
Formula used :
where,
= change in enthalpy = ?
C = heat capacity of water = 
m = total mass of sample = 2.174 + 127.4 = 129.6 g
= initial temperature = 
= final temperature = 
Now put all the given values in the above expression, we get:
Now we have to calculate the moles of AX added to water.
Now we have to calculate the enthalpy change for the solution.
As, 0.04592 moles releases heat = 7638.36 J
So, 1 moles releases heat = 
Therefore, the enthalpy change for the solution is 166.34 kJ/mol
