In this lab procedure, the ___ variable is the number of half-life cycles (time) and the ___ variable is the number (or fraction) of (radioactive) Lincolnium nuclei remaining at that time.

Independent, Dependent

Explanation:

In the given lab procedure, the number of half-life cycles or the time in which the number of nuclei in radio-active substance turns into its half would be characterized as the 'independent' variable as it directly affects the dependent variable i.e. 'the number(or fraction) of Lincolnium nuclei remaining at that time.' The number of nuclei would be the dependent variable as it bears the change or effect of a change in the independent variable(half-life cycle).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

particle   p is an electron and particle q is a neutron
