7.
Which statement best describes Percentage uncertainty?
A flask calibrated to contain one exact volume, used to make standard solutions.
The volume occupied by one mole of gas under stated conditions, about 24.0 dm3 at r.t.p.
The measurement uncertainty divided by the value measured, multiplied by 100.
The curved surface of a liquid; the bottom of the meniscus is read at eye level.
8.
Which statement best describes Volumetric flask?
A calibrated glass or plastic syringe used to collect and measure the volume of gas produced.
The volume occupied by one mole of gas under stated conditions, about 24.0 dm3 at r.t.p.
A flask calibrated to contain one exact volume, used to make standard solutions.
The heat energy change at constant pressure when molar quantities react as shown in the equation.
9.
Which statement best describes Titration?
A technique in which a solution of known concentration is added from a burette to a measured volume of another solution until the end point.
A solution whose concentration is known accurately.
The volume occupied by one mole of gas under stated conditions, about 24.0 dm3 at r.t.p.
The curved surface of a liquid; the bottom of the meniscus is read at eye level.
10.
Which statement best describes Meniscus?
A technique in which a solution of known concentration is added from a burette to a measured volume of another solution until the end point.
Extrapolating a temperature-time graph back to the time of mixing to estimate the maximum temperature change.
A flask calibrated to contain one exact volume, used to make standard solutions.
The curved surface of a liquid; the bottom of the meniscus is read at eye level.
