Answer:
c2h6
Explanation:
molecular weight=vapour density*2=2*15=30
molecular formula=empirical formula*n
n=molecular weight/empirical formula weight=30/15=2
so molecular formula2 * (ch3) alkane =c2h6

Solution:
a theory of atomic structure in which the hydrogen atom is assumed to consist of a proton as nucleus, with a single electron moving in distinct circular orbits around it, each orbit corresponding to a specific quantized energy state.
the electron energy level of the hydrogen atom can be written as:
En = -2.179×10^-18 J/ n^2
Thus for n = 3: E3 = -2.421x10^-19 J
For n = 5: E5 = -8.72x10^-20 J
Hence the energy difference between the n=3 state & n=5 state is:
2.421x10^-19J - 8.72x10^-20J
= 1.549x10^-19 J

Yes, The car will accelerate if its velocity changes in magnitude, in direction, or both. If a car is traveling at a constant speed of 35 m/s, it can be accelerating if its direction of motion is changing.
