A solution with a pH of 13 is a strong

The pH range for an acid is pH < 7 with the strength increasing downwards so an acid with pH 1 is much stronger than one with 6.

The range for a Base is pH > 7 with the strength increasing with number thus a substance with pH 14 is much stronger than a substance of pH 8.

With that said, <span>A solution with a pH of 13 would be a STRONG BASE (alkali since it is in solution).  

Additional: I attached a pH scale so that at any point in time you can check the pH scale and match it to the substance given and tell whether it is a strong or weak base or acid.

Convert the volume of CO2 you measured in the glucose reaction to moles of CO2 using the Ideal Gas Law to solve for n. Assume P
olganol [36]
The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
                                     n = PV/RT
We simply substitute the given values to the equation above,
                                 n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
                                           n = 12.20 V/T

using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene
rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.
