Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4

We have 25cm^3 of 0.1mol AgNO3.
25cm^3 = 0.025L, so we have 0.025 x 0.1 = 0.0025mol AgNO3, so
0.0025AgNO3 + 0.0025NaCl = 0.0025AgCl + 0.0025NaNO3
Change in Free Energy: ΔG(20C) = -0.064kJ (negative, so the reaction runs)
Change in Enthalpy: ΔH(20C) = -0.110kJ (negative, so the reaction is exothermic)
This reaction produces 0.358g of AgCl and 0.213g of NaNO3
