Explanation:
Atomic number refers to the number of protons in the nucleus of the atom.
and since there are 3 protons, the atomic number is 3
3) CH₃-COOH + NH₃ → CH₃-COO⁻NH₄⁺
4) 2 FeCl₃ + 3 Ag₂SO₃ → Fe₂(SO₃)₃ + 6 AgCl
5) 2 Al + 3 NiCl₂ → 2 AlCl₃ + 3 Ni
6) 4 LiCl + Pb(NO₂)₄ → 4 LiNO₂ + PbCl₄
7) 3 H₂SO₄ + 2 Al(OH)₃ → Al₂(SO₄)₃ + 6 H₂O
8) Cd(NO₃)₂ + Na₂S → CdS + 2 NaNO₃
9) Cr₂(SO₄)₃ + 3 (NH₄)₂CO₃ → Cr₂(CO₃)₃ + 3 (NH₄)₂SO₄
Answer:
The glass of water weigh once the antacid pill has dissolved will be less than the 179 grams due to evolution of carbon dioxide.
Explanation:
Mass of effervescent antacid pill = 4.00 g
Mass of water = 85 g
Mass of glass = 90 g
Total mass of the substances together : 4.00 g + 85 g + 90 g = 179 g
Effervescent antacid pill , moment it get dissolved in water carbon dioxide gas is evolves and escape from the solutions.
This means that mass of the weight of the glass of water with antacid dissolved in it will be less than 179 grams.
