How many grams of calcium phosphate can be produced when 89.3 grams of calcium chloride reacts with excess sodium phosphate?
larisa86 [58]
Balanced chemical  equation  is
3CaCl2 +2Na3PO4-->6NaCl +Ca3(PO4)2
moles of  CaCl2  =89.3g/[ (35.5x2) +40]=0.805moles
from  the  equation  above  the  ratio  of  CaCl2  to  Ca3(PO4)2  is  3:1  therefore  the  moles  of Ca3(PO4)2  is 0.809/3=0.268moles
mass  is  therefore  0.268  x310.18(R.F.M of   Ca3(PO4)2 ) =83.23grams

QveST [7]

Answer:

Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus

Explanation:

<u>Organelles</u> are membrane bound only in eukaryotic ccells.

Prokaryotic cells unlike eukaryotic cells, do <u>not have membrane bound organlles.</u>

Something that is found in <u>both prokaryotic and eukaryotic cells is the cytoplasm</u>, which is fluid that is inside the whole cell.

Unlike eukaryotic cells, <u>prokaryotic cells have loose DNA</u>, which floats around the cell quite literally.

The only way DNA is stored in eukaroyotic cells is in the <u>nucelus</u>, which is only found in eukaryotic cells, not prokaryotic.

Hope this helps ;)
