Aflask is charged with 3.00 atm of dinitrogen tetroxide gas and 2.00 atm of nitrogen dioxide gas at 25ºc and allowed to reach equilibrium.
n2o4(> 2 no2(g) kp = 0.316
which of the following best describes the system within the flask once equilibrium has been established?
the rate of the decomposition of n2o4(g) is equal to the rate of formation of no2(g).
the partial pressure of n2o4(g) is equal to the partial pressure of no2(g).
the rate of the decomposition of n2o4(g) is greater than the rate of formation of no2(g).
the rate of the decomposition of n2o4(g) is less than the rate of formation of no2(g).
answer: the atomic mass of these species is different and atomic number remains same.
isotopes are the chemical species of the same element having different number of neutrons.atomic number is equal to the number of protons or electrons present in that element.
atomic number = number of electrons = number of protonsatomic mass is defined as the sum of number of protons and neutrons contained in an atom.
atomic mass = number of protons + number of neutrons
for isotopes, as the number of neutrons differ, the atomic mass also differs.
for example: carbon has 3 naturally occurring isotopes: . the atomic number remains the same but atomic mass differs.
hence, for isotopes, the atomic mass of these species is different and atomic number remains same.
by using relative and radiometric dating methods hope this
the first blank can be filled with option b, that is, radiant energy, and the second blank can be filled with option c, that is, the sun.
radiant energy is most generally applied in the fields of solar energy, radiometry, lighting, and heating, however, is also in certain cases used in other branches like telecommunications. in modern uses, comprising the transmission of power from one location to another, radiant energy is also used to signify towards the electromagnetic waves. thus, it is the form of energy that can move from place to place across the universe.
a surface heated by the sun transforms the energy of the light into infrared energy, that is, a form of radiant energy, thus, the main source of radiant energy on earth is the sun.
