Answer:
3 P atoms
Explanation:
Al₂P₃ => contains 2 Aluminum ions (2Al⁺³) and 3 Phosphide ions (3P⁻³) ... The ions (charged particles) are from atoms that have lost or gained electrons during the bonding process. So, Al₂P₃ => P⁻³ ions from 3 P atoms.
Answer:
Explanation:
The human body is constantly radiating heat to its surroundings, and human comfort is closely tied to the rate of this radiation we need to know this because its part of a daily life.
Answer:
The right choice is c. Water molecules have a weakly positive hydrogen end.
Explanation:
The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.
so
a. Water molecules have a nonpolar bond.
It is wrong choice because water has polar bond .
b. Water molecules have a weakly positive oxygen end.
Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.
c. Water molecules have a weakly positive hydrogen end.
This is the right choice.
d. Water molecules have two oxygen and two hydrogen atoms
It is wrong choice because water has one oxygen and two hydrogen atoms
So, the right choice is
c. Water molecules have a weakly positive hydrogen end.
Answer:
Explanation:
Mass in grams is given by
where
n = Number of molecules
= Avogadro's number = 
M = Molar mass of molecule
Molar mass of 
= 34.0147 g/mol
Mass of 
Molar mass of 
= 64.066 g/mol
Mass of 
Molar mass of 
= 48 g/mol
Mass of 
Molar mass of 
= 16.04 g/mol
Mass of
