The first one is Propane
The second one is HEPTANE
The third one is <em>octane</em>
<em>The</em><em> </em><em>4th</em><em> </em><em>is</em><em> </em><em>butane</em>
<em>the</em><em> </em><em>5th</em><em> </em><em>is</em><em> </em><em>decane</em><em> </em>
Answer:
Option 3 = i.e. If you add the masses of all the products after fission, they are LESS than the mass of the reactants
Explanation:
Nuclear fission: Is the process in which the nucleus of radioactive element with higher mass undergoes fission and get into fragment of smaller mass with release of high energy.
The products of the nuclear fission are the fragment of smaller nuclei.
For example, larger nucleus that of uranium split into two small nuclei along with some neutrons, energy and gamma rays.
The mass of the original atom always more than the sum of the atomic masses of the atoms produce by fission. The reason is neutrons and kinetic energy lost, and upon cooling we get product masses less than original.
Answer:
By Filtration , Distillation , and then using a Separating Funnel
Explanation:
1) Use filtration to separate sand from sea water. Sand remains on the filter paper and the rest of salty water with oil is collected in the flask.'
2) Use distillation to separate salt from the water and oil collected in the flask. Water boils at 100°C , salt doesn't. So evaporate the water an then condense it in another container.
3) Use Separating Funnel to separate oil and water as both have different density.
Their are natural since they come from trees which is natural
