Answer:
Chemical
Explanation:
The change was chemical, because it can no longer be returned to the original form. You cannot get back the bubbles or fizz from the air.
The nuclear equation that describes the alpha decay of Polonium-210 can be written like this:
210/
84Po→206/82Pb+4/2 He
Answer:
pH = - log [2.12 x 10^-3]
what is the log of 2.22 x 10^-3]
Take the opposite of that,
That is the pH, now, just make certain you use the correct significant figures.
Explanation:
Answer:
baby which question you want to answer me
You need to use the equation PV = nRT
The only “trick” in these problems is you need to use the correct UNITS. Especially for the “R” value.
If you get the units (eg temps in Celsius or Kelvin) corresponding to the correct “matching” units of the other variables.
You need to convert the temp into Kelvin first
