A solid will start to melt when it reaches its melting point. For example the melting point of Helium is -272° Celsius and the melting point of Carbon is 3500° Celsius . Helium has the lowest melting point and carbon has the highest melting point in the periodic table.
MgCl₂ ---> Mg(2+) + 2Cl(-)

The molality of chloride ions is 0,02M.
The correct answer is option C, that is, it appears that ants live in colonies.
The statement, that is, pizza is the best-tasting food on Earth is false, as it cannot be tested. The statement, that is, I believe that there is life on other planets is not a scientific statement, as it is just a belief.

The statement, that is, it appears that ants live in colonies is a scientific statement as one can observe and test this.
Answer:
Explanation:
Expanded Structure shows all the atoms and the bonds of the molecule. It is important to remember, each Carbon molecule have four bonds, while the Hydrogen just one. So:
1)
Pentene. 5 Carbon molecules, 10 Hydrogen molecules. It's an isomer, so this organic compound has multiple arrangements.
2) 
Ethane. 2 Carbon and 6 Hydrogen Molecules. Check it below.
The water molecules are moving so slow that they end up sticking together to form a solid
