Spectator ion are ions which remain unchanged during chemical equation and does not affect equilibrium
chemical equation for the reaction is as follows
NaSO4 +Babr2 ---> 2 Nabr + BaSO4
ionic equation is as follows
Ba ^+2 + SO^-2 --->BaSO4(s)
therefore the spectator ion are Na+ and Br- ions
Answer:
The empirical formula is C₂H₃
Explanation:
The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound.
The reaction of combustion for a CₐHₓ is:
CₐHₓ + (a+x/4) O₂ → a CO₂ + ˣ/₂ H₂O
The moles obtained are
15,3 g of CO₂ × 
= 0,3476 moles of CO₂≡moles of C
4,70 g of H₂O × 
= 0,2608 moles of H₂O × 2 = 0,5216 moles of H.
The ratio H:C is 0,5216/0,3476= 1,5. That means you have 1,5 H per 1C, that is the same than 3H per 2C. Thus, empirical formula is:
C₂H₃

I believe the charge on an electron is negative
The answer is 6.71 moles. A sample of 97.994 grams of phosphoric acid is equal to one mole H3PO4. This molar mass of phosphoric acid is the amount or mass in grams in one mole of H3PO4. The number of moles of the H3PO4 compound can be determined using the molar mass of phosphoric acid:
moles H3PO4 = 658 grams H3PO4 * (1mol H3PO4 / 97.994 g H3PO4)
= 6.71 mol
