Answer:
The least whole number coefficient for HNO₃ is 6
Explanation:
The chemical equation above is the reaction between calcium orthophosphate and nitric acid.
To balance a chemical equation, we have to consider law of conservation of matter which states that matter can neither be created nor destroyed.
What this law implies is that, whatever we have at the reactant side must be equal to whatever is obtainable at the product side.
The above equation is
Ca₃(PO₄)₂ + HNO₃ → Ca(NO₃)₂ + H₃PO₄
To balance the equation, we'll have to check the number of atoms at each side and possibly balance the equation with the number of moles.
The balanced equation is
Ca₃(PO₄)₂ + 6HNO₃ → 3Ca(NO₃)₂ + 2H₃PO₄
From the balanced equation above, we can see that the number of calcium (Ca), Phosphorus (P), Oxygen(O), Nitrogen(N) and hydrogen (H) are balanced at both sides of the equation.
The least number coefficient for HNO₃ is 6
POCl3 is the chemical formula of this compound. Also known as <span>Phosphoryl chloride.</span>
We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.
The formula of the complex is: [Fe(<em>en</em>)₃]³⁺, where, <em>en</em> is abbreviation of ethylenediamine.
Ethylenediamine (<em>en</em>) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(<em>en</em>)₃]³⁺ with a co-ordination number of six.
Answer:
7.2 gm or 0.0072 Kg
Explanation:
Let k be the kg of packets that are to be used.
36 X 200 mg = 1000 X k
=> k = 7.2 gm.
