96.4567
Explanation:
245 cm in inches: two hundred and forty-five cm are equal to 245/2.54 = 96.45669 inches.
Answer:
I'm sorry I couldn't find it, I looked all over the internet
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4
Reaction:
FeCl3(aq) + 3AgNO3(aq) → Fe(NO3)3(aq) + 3AgCl(s)
Net ionic:
Ag + (aq) + Cl − (aq) → AgCl(s)
Explanation:
The evidence that a double replacement reaction has happened is the formation of a solid, liquid or gas from aqueous solutions. I’m this case case silver chloride is a precipitate.
The compound originally contained KNO₃ solution.
Explanation:
When a mixture which contains either Pb(NO₃)₂ or KNO₃ is added with NaCl solution, no reaction takes place. This confirms the presence of KNO₃ in the solution.
The reason behind the above activity can be attributed to the lower placement of Na (sodium) in reactivity charge than potassium (K). Hence, it cannot displace Potassium (K) from the aqueous KNO₃ solution. Whereas the NaCl reacts with Pb(NO₃)₂ to produce white insoluble precipitate of PbCl₂. This confirms the presence of KNO₃ in solution.
