Wheres the finished equation...
PH=-lg[H⁺]
pH=-lg(2.8×10⁻⁹)=8.553
pOH=14-pH
pOH=14-8.553=5.447
[OH⁻]=10^(-pOH)
[OH⁻]=10⁻⁵·⁴⁴⁷=3.6×10⁻⁶
As we know V1/T1=V2/T2
so, V1=3.60
V2=6.25
T1=45c=318k
T2=required
solution!
T2=V2 multiply by T1/V1 so
put the values and find your answer which should be 552k
He should transfer the food to another cooler.
This is because for a refrigerator, the temperature should be kept at 40 degrees Fahrenheit in order to slow down the development of the spoilage bacteria that develop in food in the form of color or odor.
Basic copper carbonate is decomposed by acids, such as solutions of hydrochloric acid HCl, into the copper(II) salt and carbon dioxide. In 1794 the French chemist Joseph Louis Proust (1754–1826) thermally decomposed copper carbonate to CO2and CuO, cupric oxide.
