<h3>Answer:</h3>

                    It is fat-soluble

<h3>Explanation:</h3>

                         The cheeseburger grease adhered to cloths can not be washed by simple rinsing it with water. This is because of the fact that "<em>Like Dissolves Like</em>". As grease is non-polar in nature therefore it will show no interaction with water because water is polar in nature. Hence, in order to make interactions of grease we must add some sort of non polar solvent like Tetrachloroethylene (C₂Cl₄). Now, both being non-polar in nature will interact, make attractions and grease will happily leave with Tetrachloroethylene leaving the cloth clean again.

<h3>Remember:</h3>

                   Tetrachloroethylene is non polar because the four chlorine atoms about the double bond cancel out each others effect making the dipole moment zero hence, the overall molecule becomes non-polar.

__ SnCl4 → __ Sn + __ Cl2
Kisachek [45]

Answer:

Sn (s) + 2 Cl2 (g) → SnCl4 (l)

This is an oxidation-reduction (redox) reaction:

4 Cl0 + 4 e- → 4 Cl-I

(reduction)

Sn0 - 4 e- → SnIV

(oxidation)

Cl2 is an oxidizing agent, Sn is a reducing agent.

Reactants:

when methane reacts with oxygen, the products are carbon dioxide and water. How many grams of carbon dilxide are formed if 30 g
Wittaler [7]

Answer:

CH4+2O2→CO2+2H2O

Moles of oxygen=3232=1

Moles of carbon dioxide=4422=0.5

Moles of water=1818=1

1 mole of methane reacts with 2 moles of oxygen to give 1 mole of CO2 and 2 moles of water so 0.5 mole of methane will be required which is equal to 0.5×16=8g.

Explanation:

8g

How have ideas about the atom changed in the last two centureies?
dsp73
In the past a scientist named dalton produced an atomic theory. There were certain problems regarding his views. So, later on scientists like chadwick, rutherford and thompson added some fresh light for the real identification of the atom.
dalton said the atom was the smallest unit and it CANNOT BE DIVIDED ANY FURTHER.
NOTE... this was renected with the discovery of the proton, neutron and electron as the sub atomic particles.
