T = 2T , P = 2P as given in the question
Volume = mass *density
Now apply ideal gas law
PV=nRT
V = nRT/P
substitute value of V and P
V = nR2T/2P
V =nRT/P
mass*density = nRT/P
density will not change
The ionic charge of oxygen is -2.
Hope this helps! ;)
The answer is Decomposition.
Answer:
1500 mmol.
Explanation:
Hello,
In this case, for such monovalent potassium species, we can verify that 1 mEq equals 1 mmol, therefore, the required solution is shown below:

Which means that also 1500 mmol of monovalent potassium ions are contained in the liter.
Regards.
Answer:
In fact, a full scuba tank will gain about 5-6 psi for every degree of temperature increase. This is one reason that full tanks should not be left in a hot trunk of a car. A tank filled to 3000 psi could easily reach 3500 psi if the temperature of it increased substantially.
