Answer:
acetic acid, sodium hydroxide
Explanation:
A strong acid is an acid that ionizes in water to give all its hydrogen ion. Weak acid only ionize to a certain degree. Acetic acid (CH3COOH) only ionize to give one hydrogen ion despite having other hydrogen atom. This account for its weak nature as an acid as shown below:
CH3COOH <=> H^+ + CH3COO^-
A strong base is a base that ionizes in water to give all it hydroxide ion. Sodium hydroxide(NaOH) ionizes to give all its hydroxide ions. This make it a strong base as shown below;
NaOH <=> Na^+ + OH^-

Answer:
The answer to your question is T = 7.25 °K
Explanation:
Data
Temperature = ?
moles = 0.80
volume = 275 ml
pressure = 175 kPa
constant of ideal gases = 0.082 atm l/ mol °K
Process
1.- Use the ideal gas law to solve this problem
PV = nRT
-Solve for Temperature
T = PV / nR
2.- Convert Pressure to atm
1 atm --------------- 101.325 kPa
x --------------- 175 kPa
x = (175 x 1) / 101.325
x = 1.73 atm
3.- Convert volume to liters
1000 ml ---------------- 1 l
275 ml ----------------- x
x = (275 x 1) / 1000
x = 0.275 l
4.- Find the temperature
T = (0.275 x 1.73) / (0.8 x 0.082)
-Simplification
T = 0.476 / 0.0656
-Result
T = 7.25 °K
Answer:
0.231 mol/L
Explanation:
The first step is to write the balanced equation for this reaction:
The second step is to find the number of moles in the acid:
number of moles = volume * concentration
= 0.035 L * 0.275 mol/L
= 0.009625 mol
The third step is to use the molar ratio from the balanced chemical equation to find the number of moles of NaOH that can neutralize 0.009625 mol of sulphuric acid.
n(sulphuric acid) : n(sodium hydroxide)
1 : 2
0.009625 mol : x
x = 0.01925 mol
Fourth step is to calculate the concentration of sodium hydroxide:
