Fluoride is added to drinking water to prevent tooth decay
Fluoride is added to water to help prevent tooth decay and strengthen enamel. It helps to reduce the risk of cavities and promote oral health.
sodium fluoride, potassium fluoride, stannous fluoride, sodium fluoride phosphate, etc.
Flouride
When coffee is added to water, that is a physical change. The coffee does not undergo a chemical reaction, the various chemical constituents of coffee remain the same. What changes is that the coffee is dissolved in water. If the water were to evaporate, leaving the coffee behind, it would be the same as it was (not counting the loss of some volatile constituents which would also evaporate, along with the water) before it was added to water.
Sodium hypochlorite is dissociated in water.
The answer is 180 g dry chemical.
Chemical, producing hydrogen chloride which when added to water produces hydrochloric acid.
It's a physical action without toothpaste. Many toothpaste have inactive ingredients, and are only there to "taste good". Toothpaste with fluoride, baking soda, and other common dental ingredients will undergo small chemical changes when they come in contact with water (when baking soda in water come together it creates a chemical reaction). So in some respects it's both!
carbamide peroxide
Fluoride.
They have sharp teeth and they use them if the animal is in the water they get out of the water
Hydrolysis is a chemical reaction. Molecules of water are split into hydrogen cations and hydroxide anions in the process of a chemical mechanism.
Try using Colgate Sensitive Enamel Protect toothpaste to protect the enamel on your teeth. Also you can drink lots of water after eating acidic foods to wash the acid off your teeth.

Adding hydrogen peroxide to bleach will cause it to foam up due to the release of oxygen gas. This is because the reaction between hydrogen peroxide and bleach produces oxygen gas, leading to the foaming effect.

there is no chemical change when ammonium chloride is added to water. NH4Cl + H2O + heat -> products. it also cold when it is dissolved in water.
