Answer:
[OH-]= 1.995×10^-11M
Explanation:
pOH= 14- pH = 14-3.3 =10.7
pOH= -log[OH-]
[OH-]=antilog (-10.7)
[OH-]= 1.995×10^-11M
Answer: Naprox 350 is the anwser
Explanation: because to fourmals mixed makes naprox know as gr27
Answer:
603000 J
Explanation:
The following data were obtained from the question:
Energy required (Q) =...?
Mass (M) = 10000 g
Specific heat capacity (C) = 2.01 J/g°C
Overheating temperature (T2) = 121°C
Working temperature (T1) = 91°C
Change in temperature (ΔT) =.?
Change in temperature (ΔT) =T2 – T1
Change in temperature (ΔT) = 121 – 91
Change in temperature (ΔT) = 30°C
Finally, we shall determine the energe required to overheat the car as follow:
Q = MCΔT
Q = 10000 × 2.01 × 30
Q = 603000 J
Therefore, 603000 J of energy is required to overheat the car.
You gave no choices. P = mv
mass (kg) * velocity (m/s)
Since 1000 mg=1g
500mg=?
500/1000*1g=0.5g
Since we know that 500mg is 0.5g then divide 30g by 0.5g
30/0.5=60
Therefore the patients needs to take 60 tablets a day.
