Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
Chemical- it produces ammonia.
Lower the melting point
Explanation:
Salts helps to melt road by lowering the melting point. It acts as an impurity and generally, impurities low the melting point of substances.
Salts are used as an antifreeze.
- Water freezes at 0°C and forms ice/snow which can impede human and vehicular movement.
- When salt is added, it causes the depression of the freezing point by lowering it further.
- The freezing point is pegged back at -6°C.
- This way it takes more low temperature to freeze the water.
- The salt acts as an impurity and causes the depression of melting point and widening of the melting range.

Answer:
A
Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates are constant.
Explanation:
B/c chem reactions can be affected by temperature, pressure, etc. whereas, nuclear decays are constant. The decay rate itself is measured over a long period of time and it remains constant I believe.
