2018年1月10日 · In direct contrast with "HCl" vs. "HBr", "HClO" is a stronger acid than "HBrO", because "Cl" is more electronegative, which dominates over the size difference between "Cl" and "Br" due to the presence of the oxygen. Therefore, the "H"-"Cl" bond is weakened more from more uneven sharing of electrons, and weaker bond = stronger acidity.

2015年4月17日 · The Brønsted–Lowry theory is an acid–base reaction theory. The fundamental concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchange of a proton. So the anwer could only be the first pair: NH_3 and ammonium catione.

2016年1月5日 · Pale to bright pink. Your starting point here will be the balanced chemical equation for this neutralization reaction "HCl"_text((aq]) + "NH"_text(3(aq]) -> "NH"_text(4(aq])^(+) + "Cl"_text((aq])^(-) Keep in mind, you're mixing hydrochloric acid, strong acid, and ammonia, a weak base, which means that even if the neutralization is complete, the pH of the resulting solution will not be equal to ...

2015年4月15日 · The answer is A) HBr. Since all compounds exhibit weak van der Waals interactions, the criterium to go by will be the presence of dipole-dipole interactions. Dipole-dipole interactions take place in polar molecules, i.e. molecules that have a permanent dipole moment. As a result, your compound must be polar and not form hydrogen bonds. So, starting with hydrobromic acid, HBr. The molecule will ...

2014年5月17日 · The order of boiling points is: "CH"_4 < "CH"_3"OCH"_3 < "CH"_4"O" < "CaCO"_3 > The order of strengths of intermolecular forces is: "ion-ion > H-bonding > dipole-dipole > London dispersion". Compounds with stronger intermolecular forces have higher boiling points. The strongest intermolecular force in each of the compounds is: "CaCO"_3 — ion-ion attractions. "CH"_4 — London dispersion ...

2015年12月7日 · The amide ion, NH_2^-. The conjugate base of any species is that species less a proton. Ammonia less a proton is the amide ion, NH_2^-. Mass and charge are conserved as always. This species does NOT exist in water, but it is the characteristic anion in liquid ammonia, a water like solvent that will support more powerful bases than does water. The amide ion also has a conjugate base, called the ...

2016年11月13日 · "Sr"("OH")_2(aq) > "NaOH"(aq) > "NH"_3(aq) > "HBrO"(aq) > "HBr"(aq) Here's what we should know: The stronger the base, the higher the "pH", since it dissociates more in solution than weaker bases, thus making it more basic and raising the "pH". The stronger the acid, the lower the "pH", since it dissociates more in solution than weaker acids, thus making it more acidic and lowering the "pH ...

2014年8月6日 · Only CH₃NH₂ and CH₃OH Only CH₃NH₂ and CH₃OH can have hydrogen bonds between other molecules of the same kind. To have hydrogen bonding, you need an N, O, or F atom in one molecule and an H attached to an N, O, or F atom in another molecule. See What is a Hydrogen bond? CH₃F has an F atom, but no H-F bonds It cannot form hydrogen bonds with other CH₃F molecules. CH₃NH₂ has ...

2018年4月17日 · Here's what I got. Hydrobromic acid, "HBr", is a strong acid and sodium hydroxide, "NaOH", is a strong base, so right from the start, you know that you're dealing with a neutralization reaction. This should tell you that the net ionic equation will involve the hydrogen cations--or hydronium cations, "H"_3"O"^(+)--produced by the strong acid and hydroxide anions produced by the strong base ...

Balancing a redox reaction requires identifying the oxidation numbers in the net ionic equation, breaking the equation into half reactions, adding the electrons, balancing the charges with the addition of hydrogen or hydroxide ions, and then completing the equation.
