the mass of the shells will remain the same because you can not change mass even if you were to leave this planet and go to the moon your weight would change but your mass remains the same
Answer:
1 ) Electrovalent compounds are formed by the complete transfer of electrons while covalent compounds are formed by sharing of electrons between 2 atoms.
2) Electrovalent compounds are more soluble in polar solvents like water while covalent compounds are more soluble in non-polar solvents like methane.
Answer:
the strongest is fluoroantimonic acid and the weakest is hydrocyanic acid
<span>Molds are created to achieve a
specific design of a material. These materials either came from a process of
having a higher or lower temperature. Therefore, the molder must have thermal
resistant properties. Low melting points means that the material to be shaped
came from a cooler process. Wood and metal have higher thermal conductivity and
therefore can easily be cooled. The wax can turn really hard and can be
unbreakable when present in colder materials due to the lipids present in it. Clay
however can become a mold because of its low melting point.</span>
