Question

e precipitate that forms when solutions of Na3PO4 and Fe(NO2)3 are mixed? 43) 2) What is the precini A) Fe3PO4 B) PO4NO3 C) NaFe D) NaNO3 E) FePO4 RUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 44) One atomic mass unit is the same as one gram. 45) In electrolysis, electrical energy is used to drive a non-spontaneous oxidation-reduction reaction to occur. 45) - 46) One mole of iron contains 6.022 x 1023 grams of Fe. 47) The formula mass of a compound is calculated by adding together the number of atoms 40 that make up the compound. 48) During an oxidation-reduction reaction, the oxidizing agent loses electrons. 49) The conversion of Fe2+ to Fe3+ is an oxidation reaction. 50) If the atomic mass of hydrogen is 1.01 amu, a mole of H2 will weigh 1.01 g.

Answer 1

43 ans'- The - reaction is Nazpe (as) + Fe (nog), los NaNo las I + Fepog (5) 30 the pricipitate © FePO4 that forms is 44 ans - False Because I amu equals to 1.66 x 102 AS. Ans - True. In librolysis, enterual elutrical energy is supplied

Date : 1 46 Ans - False I mde of fe contains 55.85 g of 42. Aus True 48. Ans? I False Because the oxidising agent gains electrons 49. Ans: I True Because oxidation number of fe change from +2 to +3. so. Aus False atomie man of th will wagh is 1.01 amu than Imole of hydrogen 2.02g.
