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).

Which kind of substance needs more energy to undergo an increase of 25 degrees Celsius something with a high or low specific hea
Nikolay [14]
<span> The substance that needs more energy to undergo an increase of 25°C will have a higher specific heat, because energy depends directly on specific heat.

Q = cm∆T
where c = specific heat of the substance,
m = mass
∆T = temperature difference </span>

A scientist is examining a mixture of nitrogen, hydrogen, and ammonia. The individual pressures that are exerted by nitrogen and
Svetach [21]
Using Daltons Law which states that the total pressure of a gas mixture is the sum of the gasses partial pressure.Thus,

Pt(total pressure)= P1+P2+P3
where
Pt= 0.90 atm
P1= 0.26 atm
P2 = 0.28 atm
P3 = ?
substitute the formula with known variables
P3= 0.90 atm-(0.26atm+0.28atm)
P3 = 0.36 atm

The partial pressure of ammonia is 0.36 atm
