No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)
Answer:
Is there any other part to this question? If not I'm pretty sure the answer is 205.5 kJ
Explanation:
C=0.10 mol/l
pH=-lg[H⁺]
HCl = H⁺ + Cl⁻
pH=-lgc
pH=-lg0.10=1.0
pH=1.0
the answer is H is the cation
Explanation :
The general formula of an acid is represented as, in which 'H' is hydrogen cation and 'X' is a non-metal or a poly-atomic anion.
For example : etc.
All the acids produces hydrogen ion, in an aqueous solution while the base produces hydroxide ion, in an aqueous solution.
