Explanation:
In a single replacement reaction, one element must displace another element from its compound.
Thus, we must consider the reactivity series, because an element lower down in the series cannot replace one that is above it.
In a double replacement reaction, the cations change partners with the anions. All we need consider are the solubilities of the new cation-anion partners.
Answer:
Based on these values and on consideration of molecular geometry, the H-Se bond can be considered almost _____non-polar___ and the molecule is __polar_____.
Explanation:
Looking at the difference in electro negativity of the two elements; hydrogen and selenium, one may be led to the conclusion that the molecule is nonpolar since the magnitude of electronegative between the two bonding atoms is minimal.
However, electro negativity difference alone is insufficient to determine the polarity of a molecule. The structure of the molecule is also considered. Based on the structure of the molecule, it is expected to have a dipole moment. Hence the molecule is polar.
Answer:
TRUE!!!
Explanation:
The transfer of thermal energy is called heat. Therefore, a heating system is a system for the transfer of thermal energy. Regardless of the type of heating system in a home, the basic function is the same: to produce thermal energy and transfer it to air throughout the house.
