Answer:
Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes
Answer:
solid at room temperature (with the exception of mercury)
usually shiny.
high melting point.
good conductor of heat.
good conductor of electricity.
low ionization energies.
low electro-negativities.
malleable – able to be pounded into sheets.
NaHCO3 = 22.99 + 1.008 + 16(3) = 83.99 g/mol
<span>Na = 22.99g/83.99 g weight of molecule =.2727 or 27.27% </span>
<span>3.0 g* .2727 = 0.8211 grams of sodium in sample of NaHCO3
</span><span>0.8211 grams Na + 1.266 grams Cl = 2.087 grams</span>
Answer :
(A) The number of moles of ions per liter is, 0.1 moles/L
(B) The number of molecules of ion is,
(C) The pH of the solution will be, 4
<u>Solution for part A :</u>
First we have to calculate the pOH of the solution.
As we know that,
Now we have to calculate the moles of ion per liter.
<u>Solution for part B :</u>
First we have to calculate the ion concentration.
Now we have to calculate the number of molecules of ion
As, 1 mole contains number of molecules of ion
So, moles contains number of molecules of ion
<u>Solution for part C :</u>
