Astronomy is a branch of science that studies the Earth and
the universe. Since the age of the Earth
will be based on how it starts, or how the universe starts, astronomy surely
has the most proof that Earth is approximately 4.6 billion years old.
Above question is incomplete. Complete question is
<span>What is the missing number in the nuclear reaction 175 78 pt -- 4 2 He plus 76 Os?
....................................................................................................................
Solution:
Reaction involved in present nuclear event is
</span>175 78 Pt → 4 2 He + 76 Os
In above nuclear reaction, atomic mass number of Os is missing. The atomic mass number of Os = 175 - 4 = 171
Thus, complete nuclear can be written as
175 78 Pt → 4 2 He + 171 76 Os
The simplest Organic compounds are made up of only Carbon and Hydrogenatoms only. Compounds of Carbon andHydrogen only are called Hydrocarbons. The simplest Hydrocarbon is methane, CH4.
