The volume is 19.76987448 by taking the known variables mass=18.9g and density=0.956g/ml
To get volume you divide the mass by the density which gives you about
19.77 ml in volume
Answer:
A. H₃O⁺ + CN⁻ → H₂O + HCN
B. OH⁻ + NH₄⁺ → NH₃ + H₂O
C. CN⁻ + NH₄⁺ → HCN + NH₃
D. HSO₄⁻ + CH₃COO⁻ → SO₄²⁻ + CH₃COOH
E. ClO⁻ + NH₃ → NO REACTION
Explanation:
Part A.
Sodium cyanide consist of Na⁺ and CN⁻ ions. CN⁻ is a conjugate base and accept H⁺ ion from nitric acid to form HCN (hydrogen cyanide).
Part B.
Ammonium chloride consist of NH₄⁺ and Cl⁻ ions. Sodium hydroxide is a strong base dissociate completely in solution convert into ammonium hydroxide and sodium chloride.
Part C.
Sodium cyanide consist of counter ion Na⁺ . CN⁻ combined with ammonium bromide to form ammonium cyanide and sodium bromide.
Part D.
Potassium hydrohen sulphate consist of potassium counter and hydrogen sulphate ion. Hydrogen sulphate combined with acetate ion to form acetic acid and sulphate ion.
Part E.
There have no reaction because hypochlorite and ammonia both are bases.
The Lewis structure of PF3 shows that the central phosphorus atom has one non bonding and three bonding electron pairs. In this compound each Phosphorus atom contributes 5 valence electrons while each fluoride contributes 7 valence electrons making a total of 26 valence electrons. The central Phosphorus atom forms single bonds with each of the fluoride atoms. Phosphorus, therefore ends up with a non-bonding pair since the fluoride atoms already have 8 electrons around them. <span />
Answer:
The energy absorbed in the first move is greater than the energy released in the second move.
Explanation:
When the electron goes up levels it absorbs energy to enter that higher energy state. When it goes down, it releases energy but just not as much because 1-4 is more than 4-2.
Answer:
Atomic size gradually decreases from left to right across a period of elements.
