What is the theoretical yield of NaBr
dolphi86 [110]

The theoretical yield of NaBr given that 2.36 moles of FeBr₃ reacts is 7.08 moles

<h3>Balanced equation </h3>

2FeBr₃ + 3Na₂S → Fе₂S₃ + 6NaBr

From the balanced equation above,

2 moles FeBr₃ reacted to produce 6 moles of NaBr

<h3>How to determine the theoretical yield of NaBr</h3>

From the balanced equation above,

2 moles FeBr₃ reacted to produce 6 moles of NaBr

Therefore,

2.36 moles FeBr₃ will react to produce = (2.36 × 6) / 2 = 7.08 moles of NaBr

Therefore,

Thus, the theoretical yield of NaBr is 7.08 moles

A large weather balloon filled with helium has a volume of 7.00 x 102 L at STP. Which expression should be used to find the mass
balandron [24]

Answer:

mass of Helium = mole of Helium x Molarmass of Helium

Explanation:

Mole of Helium = volume of Helium/ 22.4dm^3/mol

                          = 7.00 x 10^2/22.4

                          = 31.25mol

Mass of Helium = mole of Helium x Molarmass of Helium

                           = 31.25mol x 4g/mol

                           = 125g
