Answer:
3 significant figure
Explanation:
Trailing zeros in a number are significant ONLY is the number contains a decimal point.

Answer:
Synthetic detergents can be used for washing purposes even when the water is hard, whereas soaps are not suitable for washing with hard water. This is because of the fact that synthetic detergents can lather with hard water. Hence, Synthetic detergents better than soaps.
Explanation:
mole of acid/mole of base=(concentration of acid×volume of acid)/(concentration of base×volume of base)
Na/Nb=CaVa/CbVb
1/2=(Ca×16.7)/(0.2×25)
0.2×25=2×Ca×16.7
Ca=(0.2×25)/(2×16.7)
Ca=0.15mol/dm³
mole of acid=Concentration×volume
mole of acid=0.15×(16.7/1000)
mole of acid=2.5×10^-3moles
Answer:
1.25 M HCO₃⁻ / 1.25 M CO₃²⁻
Explanation:
Buffer capacity refers to the amount of a strong acid or base required per liter of the buffer to change its pH by one. This amount is directly related to the concentration of the conjugate acid-base pair in the buffer since the buffer pair neutralizes the strong acid or base.
Thus, the highest buffer capacity is found in the solution that has the highest concentration of the conjugate acid-base pair, which is 1.25 M HCO₃⁻ / 1.25 M CO₃²⁻
