Answer 1

Answer:

1-sodium bicarbonate becomes sodium carbonate and carbon dioxide is liberated

3- although enamel is the hardest substance of our body but when we eat food that contains sugar or carbohydrates they stay at our teeth and over a period of time they become bacteria which re capable of producing acids that can cause cavity

you can prevent it by brushing twice a day and remove all the food from your teeth and between the teeth
