Answer:
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
Explanation:
Answer:
H2O molecules are thus able to form an average of 4 H-bonds. H2O has a higher boiling point than NH3 because (i) the H-bonds are stronger and (ii) it contains twice as many H-bonds. H2O has a higher boiling point than HF because it contains twice as many H- bonds, despite these being individually weaker.

Answer:
Moles to Grams caco3
1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
After one half-life, one half is remaining. After two half-lives one fourth is remaining. So that would be 25%
