The temperature in degree celsius to which the gas was heated is calculated using the Charles law formula
that is V1/T1 =V2/T2
V1=88.2 ml
T1=35 +273 = 308 K
V2=123 ml
T2=?
by making T2 the formula of the subject T2=V2T1/V1
=(123 ml x308 k)/88.2 ml =429.5 K
in degree celsius = 429.5 -273= 156.5 degree celsius
Chemical Formulas (in their most basic form) are things like that.
They can get as complicated as HSO + HSO3 = H2SO4 though.
1.2mole•20.17g/1mole= 24.20g

Answer: The results of Rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2) an atom consists of a positive charge at the center where most of its mass is placed.
Explanation:
Ernest Rutherford performed an experiment in which he passed alpha particles through a thin gold foil sheet. Through this sheet some of the particles passed on to the other side but some of them were reflected back.
This experiment was done by Rutherford to prove than an atom contains a tiny and heavy nucleus. He concluded that an atom has more than empty space and electrons were present in scattered form.
Also, he concluded that an atom consists of a positive charge at the center where most of its mass is placed.
Thus, we can conclude that the results of Rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2) an atom consists of a positive charge at the center where most of its mass is placed.
