Explanation:
- Remineralization of enamel is a natural process and is of the same color.
- The saliva contains calcium, phosphate, and fluoride which helps in the neutralisation of acids present in food.
- Remineralization helps in improving the strength and functioning of the tooth by replacing calcium ions and flouride ions which were removed by demineralization.
- It helps in prevention of cavity formation in teeth and strengthens the teeth by replacing loss of calcium ions, phosphate ions, and fluoride by fluorapatite crystals that are more resistant to acids.
- Hence, the remineralized crystal is more resistant to acids.
This is false. Some plants are the same or at least very similar
At standard temperature and pressure, one mole of gas occupies 22.4 L. Knowing this, we must convert the grams to moles and moles to liters to get your answer. Here's how you do it!

With significant figures accounted for, 5.8 grams of hydrogen gas occupies
65 L.
Hope this helps!
Answer:
Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
