I believe the pH is 7. If you would like me to explain comment.
Isn't it nitrogen AND chlorine? Both are nonmetals, and they need to gain electrons in order to bond.
Answer:
0.109 g.
Explanation:
Equation of the reaction:
Na3PO4 + 3HCl --> 3NaCl + H3PO4
Number of moles of HCl = molar concentration × volume
= 0.1 × 0.04
= 0.004 mol.
By stoichiometry, 1 mole of Na3PO4 neutralises 3 moles of HCl. Therefore, number of moles of Na3PO4 = 0.004/3
= 0.0013 mol
Mass of Na3PO4 = molar mass × number of moles
= 0.0013 × 164
= 0.219 g
Since 50% of Na3PO4 was present in the sample. Let 100 g be the total mass of the substance
= 0.219 × 50 g/100 g
= 0.109 g.
Answer:
Strong acids react faster where as weak acids take time to react with any base.
Answer:
Volume
Explanation:
Volume is how much of a substance something can hold!
Hope this helped, have a nice day! :)
