Answer:
Explanation:
Chemical equation:
HCl + Fe₂O₃ → FeCl₃ + H₂O
Balanced Chemical equation:
6HCl (aq)+ Fe₂O₃(s) → 2FeCl₃(aq) + 3H₂O(l)
Ionic equation:
6H⁺(aq) + 6Cl⁻(aq) + 2Fe⁺³(aq) + 3O²⁻(aq) → 2Fe⁺³(aq) + 6Cl⁻(aq) + 3H₂O(l)
Net ionic equation:
6H⁺(aq) + 3O²⁻(aq) → 3H₂O(l)
The Cl⁻(aq) and Fe⁺³(aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
It seems that you have missed the necessary options for this answer, but anyway, the answer for this would be H20. The specie that is a conjugate acid of OH- is H20. H20 is the conjugate acid and OH- is the conjugate base. Hope this answers your question. Have a great day!
Answer; Glycerol is the solvent... (In any situation, the most abundant substance is the solvent). :)
PV = nRT, or (pressure)(volume) = (amount of gas)(universal gas constant)(temperature)
<span>You're solving for pressure, so start by rearranging the equation: </span>
<span>p = (nRT)/V </span>
<span>You're given temperature; all you need to do is convert it to Kelvin. (The universal gas constant is 8.31 J/(Kmol), so the units for temperature need to be the same.) </span>
<span>But how to figure out the rest? The question doesn't give you the size of the flask or number of moles, but it does tell you that these things don't change throughout the problem. Because they're constant, we don't have to know exactly what they are - we just have to know the *combined values* of the constants. (If this is confusing, think about it this way: a small amount of gas in a small flask will exert the same amount of pressure as a large amount of gas in a large flask, as long as the ratios are kept equal - it doesn't matter if it's 2 moles in 2 L, or 1 mole in 1 L.) </span>
<span>To figure out this constant, go back to the opening, where you're given temperature and pressure. </span>
<span>pV = nRT </span>
<span>Remember to convert celsius to kelvin! </span>
<span>(254mm Hg)(V) = nR(330K) </span>
<span>Alcohol is a more broader sense of classification including alkanols, arenols, benzyl alcohols, allyl phenols, alkenols, phenols, etc. Alkanols as one classification are compounds of ttype R-OH, where R is any alkyl group such as methyl, ethyl, propyl, butyl, pentyl, etc. Hence, alkanol is an alcohol but not all alcohols are alkanol.</span>
