Answer:
Explanation:
Metal is a material in the periodic table s much as iron or gold. A non metal is carbon in diamonds and graphite for pencil lead.
Answer:
double replacement
Explanation:
The reaction equation is given as:
Pb(NO₃)₂ + 2KI → PbI₂ + KNO₃
This reaction is a double displacement reaction.
In this form of reaction, there is an actual exchange of partners to form new compounds.
AB + CD → AD + CD
One of the following condition serves as driving force for the reaction:
- formation of an insoluble compound
- formation of water or any other non-ionizing compound
- liberation of a gaseous product.
Answer:
Percentage of mass of solute in aqueous phase is 28.57%.
Explanation:
- Fraction of solute in aqueous phase.
= Used volume of aqueous solution
= Used volume of organic solution
D = partition coefficient.
Mass of solute in aqueous phase = 
Therefore, Percentage of mass of solute in aqueous phase is 28.57%.
Answer: (F) chemical energy
Explanation:
Answer:
Explanation:
Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.
