Why is phosphorous acid more acidic than phosphoric acid?
6 votes

I'm pretty sure it is because phosphorus acid is more polar than phosphoric acid. This is because in the phosphoric acid there are more OHs and an O so it kind of balances out more towards the center. ...

Why change in enthalpy is negative?
3 votes

Bonds actually have negative potential energy. Think about it this way: in order to break a bond you have to expend energy so when a bond is created, energy must therefore naturally be released. Hence ...

Help with determining the rate constant of a reaction
3 votes

This Khan Academy Video explains it very nicely. So since this is a first order reaction $$\ce{ -\Delta N2O5/\Delta t = k[N2O5]}$$ This gives you the rate of reaction at the very start. A second ...

Does the stoichiometry effect the value of the equilibrium constant of an equilibrium reaction?
Accepted answer
2 votes

$$K_c = \mathrm{products \over reactants}$$ So this is done by multiplying the concentrations of the products and dividing by the concentrations of the reactants. The concentrations are put to the ...

The second alkene is more stable since it is symmetric. Achiral compounds are always more stable than chiral compounds due to the Gauche Effect. The explanation for why the Gauche Effect takes place ...

Equilibrium Constant in terms of Molar Concentration of Gases versus Equilibrium Constant
1 votes

I believe that the real $K_c$ would be higher. This is because in ideal gases london dispersion forces, hydrogen bonding, etc. is ignored. These would increase the number of collisions between ...

Gas densities and the atmosphere
0 votes

The density of oxygen is greater than that of nitrogen. At a certain set temperature and pressure, all gases occupy the same volume. Since oxygen has a higher molar mass, it is denser.

What does bond polarity have to do with acid strength?
Accepted answer
0 votes

This can be extrapolated to why polar substances ionize more often in water than non-polar substances. This is because water too is polar. Always remember "like dissolves like." Polar dissolves polar. ...

Try dissolving it in ethanol or some kind of alcohol. Alcohol is polar so it would dissolve the cover if the substance is polar. The dollar bill is non polar and wouldn't be dissolved.

Does salt on the snow and ice covered roads and sidewalks make the nearby air temperature cooler?
-2 votes

No. It merely reduces the melting temperature of the ice. If you've ever noticed, salt water doesn't freeze until a much lower temperature than regular water. It is because of the same reason.
