Answer : Option A) Atomic number of Arsenic is 33.
Explanation : Arsenic contains same number of protons in its atomic nucleus. In arsenic there are 33 protons found in the atomic nucleus. Hence, the atomic number will be 33. It has 5 valence electrons in its outermost shell, which is also called as valence shell. So, its valency becomes 5.
The recommended minimum amount of daily carbohydrates needed is about 130 grams.
1. HNO₃ nitric acid
Al(NO₃)₃ aluminium nitrate
You may find the the attached picture the graphical representation of both compounds.
2. You may find bellow the full equations
Explanation:
1. HNO₃ nitric acid, Al(NO₃)₃ aluminium nitrate
dissociation equation
HNO₃ (l) + H₂O (l) → NO₃⁻ (aq) + H₃O⁺ (aq)
Al(NO₃)₃ (s) + H₂O (l) → Al³⁺ (aq) + 3 NO₃⁻ (aq)
2. molecular equations
Al(OH)₃ (s) + NaOH (aq) → NaAl(OH)₄ (s)
Ba(OH)₂ (aq) + NiCl₂ (aq) → BaCl₂ (aq) + Ni(OH)₂ (s)
ionic equations
Al(OH)₃ (s) + Na⁺ (aq) + OH⁻ (aq) → NaAl(OH)₄ (s)
Ba²⁺ (aq) + 2 OH⁻ (aq) + Ni²⁺ (aq) + 2 Cl⁻ (aq) → Ba²⁺ (aq) + 2 Cl⁻ (aq) + Ni(OH)₂ (s)
