<span>Based on solubilities you can separate naphthalene and NaCl by adding the mixture to a volume of water. NaCl is highly soluble in water, so it will dissolve completely, while the insoluble naphthalen will remain solid. Next your filter the solution, washing the solid with pure water to eliminate all the NaCl from it. The NaCl will remain is solution, and you can obtain it by evaporating the water. The other method to separate naphthalene and NaCl is based on sublimation property of naphthalene: you can permit that naphthalene sublimes freely or use vacuum to accelerate the process. You use a closed vessel to catch all the gas, while the NaCl will remain solid.</span>
Answer:
2
Explanation:
The 1 & 2 are both signifigant becuase they are presented in scientific notation.
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions.
Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.
After one half-life, one half is remaining. After two half-lives one fourth is remaining. So that would be 25%
Answer:
<h3>difference is the temperature at which they melt. Snow melts at 0°C, whereas sand melts at about 1600°C! The temperature at which something melts is its melting point.</h3>
