2-methylbenzamide and 3-nitrobenzoic acid both have a melting point of

2 - methylbenzamide and 3 - nitrobenzoic acid both have melting points of 140.1 - 140.4°C.

To add, nitrobenzoic acids are derivatives of benzoic acid. Two are commercially important. They are about ten times more acidic than the parent benzoic acid.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.
