Answer:

All you have to do is put a little rubbing alcohol on a rag or paper towel, rub it over the dried marks, and the Expo marker comes right off. It works on boards, books, and most other Expo marked surfaces (like refrigerators, windows, laminate countertops, etc).

If an acid has a ka=1.6x10^-10, what is the acidity of the solution?
LUCKY_DIMON [66]
The information given in the question is not enough to determine the acidity of the solution. This is because, acidity can only be found with the equation: pH = -log [H+].
 In order to determine the acidity of the solution, the half titration point value is needed, this will make it possible to determine the value of H30+.  If the half point titration value is known, then Ka will be equivalent to pH and the value will be evaluated using the equation: - log (1.6 * 10^-10).

If a gas’s [kelvin] temperature doubles and it’s volume then remains the same, then what happens to it’s pressure?
Tamiku [17]

Answer:

The final pressure will double i.e it will be twice the initial pressure

Explanation:

T1 = T

T2 = 2T ( twice the original T)

P1 = P

P2 =?

Since the volume is constant,

P1/ T1 = P2 /T2

P/ T = P2 / 2T

Cross multiply

T x P2 = 2T x P

Divide both side by T

P2 = (2T x P) / T

P2 = 2P

Therefore, the final pressure will double i.e it will be twice the initial pressure
