Answer:
Explanation:
Assume that the volume of the stock solution is 1 L.
1. Mass of stock solution
2.Mass of NH₃
3. Moles of NH₃
4. Molar concentration of stock solution
5. Volume of stock needed for dilution
Now that you know the concentration of the stock solution, you can use the dilution formula .
to calculate the volume of stock solution.
Data:
c₁ = 14.89 mol·L⁻¹; V₁ = ?
c₂ = 0.500 mol·L⁻¹; V₂ = 600 mL
Calculations:
Answer:
HF ≥ H₂O because the HF bond is more polar than the OH bond.
Explanation:
Electrons in the bond will not be shared equally. Hydrogen electronegativity value is 2,1 but Fluorine is 4, so electrons in the covalent bond will be more attracted to Fluorine. The electron cloud will be more distorted towards Fluorine.
I hope this is correct, and as always, I am joyous to assist anyone at any time.
<span>As can be seen from the chemical formula, Ca(No3)2 is made up of Calcium, Nitrogen and oxygen. If the appropriate amount of energy is used on the compound, the bonds will disintegrate and the compound will decompose into the individual elements of Calcium, Nitrogen and oxygen</span>
