Answer is: defining the components of nuclei.
Rutherford theorized that atoms have their charge concentrated in a very small nucleus.
This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model, because it shows that most of the atom is empty space.
Rutherford conducted research that led to the first splitting of the atom in a nuclear reaction.
A triple bond<span> is one </span>sigma<span> and two </span>pi bonds<span>. A </span>sigma bond<span> is your basic head-on covalent </span>bond<span>, with the </span>bond<span> in line with the </span>bonding<span> orbitals. You can only ever have one </span>sigma bond between<span> any two atoms. A </span>pi bond<span> is a covalent </span>bond between<span> orbitals perpendicular to the </span>bond<span> direction, usually p-orbitals (nevers)</span>

The population will get low because the food we eat is animals which is species then the animals that eat that prey will die off because that might be there only prey....then if more species is gone there will be nothing left
I Hope this helped
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm
PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/ 8.314 kpa*L / mol*K * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams
