Answer:
Explanation:
2-octene is a structural isomer of octene. Octene is an unsaturated hydrocarbon (alkene) with 8 carbon atoms. <u>The structural formula of 2-octene is seen below</u>
H H H H H H
I I I I I I
H- C - C = C - C - C - C - C - C - H
I I I I I I I I
H H H H H H H H
The structural formula of 2-octene is different from that of octene in the sense that, it's double bond is found in between the second and the third carbon (on the second bond position).
Long wave I think is the correct answer
Answer:
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range is much larger in a spring tide than in a low tide.
Explanation:
(difference in water level between high and low tide)
Answer: Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution.

Hope this helps!
Phosphoric acid has 3 pKa values (pKa1=2.1, pKa2=6.9, pKa3= 12.4) and after 3 ionization it gives 3 types of ions at different pKa values:
H₃PO₄(aq) + H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq) pKₐ₁
<span>
</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq) pKₐ₂
HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq) pKₐ₃
The last equilibrium is associated with the highest pKa value (12.4) of phosphoric acid. There the last OH group will lose its hydrogen and hydrogen phosphate ion (HPO₄²⁻) turns into phosphate ion (PO₄³⁻).
