They are called the terrestrial planets and are smaller than the others. They are he hottest planets and closest to the sun and take less time to rotate the sun.
Moles H2 required = 3 x 0.230=0.690
<span>moles H2 in excess = 0.750 -0.690 =0.060 </span>
<span>the ratio between N2 and NH3 is 1 : 2 </span>
<span>moles NH3 = 0.230 x 2 = 0.460</span>
Answer:just breath its ok just use brainly
Explanation:
Answer:
The only intermolecular forces present in the compound Hexane are London dispersion forces which are generally the weakest. Hexane's molecular structure proves that Dipole-Dipole forces wont exist as there aren't very polar bonds in the structure.
the balanced equation for the above reaction is as follows;
3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl
stoichiometry of NiCl₂ to K₃PO₄ is 3:2
the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol
according to molar ratio
if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄
then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄
molarity of given K₃PO₄ solution - 0.205 M
there are 0.205 mol in 1000 mL
therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL
volume of K₃PO₄ needed is 4.44 mL
