M(NaCl)/{2M(NaCl)}=m(Cl₂)/M(Cl₂)
m(Cl₂)=M(Cl₂)m(NaCl)/{2M(NaCl)}
m(Cl₂)=70.90*7.5/{2*58.44}=4.55 g
m(Cl₂)=4.55 g

Answer: when concentrations of acid and base are same, pH = pKa
PH = 12.38 pOH = 1.62
Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00
Answer:
1-Octanol
Explanation:
Count the amount of carbon atoms in the chain. Nomenclature includes the position of the largest functional group position in the molecule.
In this case the carbon chain has 8 carbon atoms and one hydroxide functional group (OH)
1 (hydroxide is listed first in the carbon chain) - Oct(8 carbons) + anol (Alkanol hydrocarbon with a hydroxide group, use anol suffix )
= 1 - Octanol
The molecule that contains a total of eight carbon atoms :
b. 2-methyl-heptane
formula of 2-methyl-heptane
C8H18 ( or CH3CH(CH3)CH2(CH2)3CH3 rather )
hope this help
