Chemistry
1 answer:
lilavasa [31]3 years ago
7 0

Answer:

D. 4

Explanation:

Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.

Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface.

Hence, from the diagram provided above, the thin beam of light which illustrates reflection is the fourth because as it hit the surface, it bounced back to the medium from which it was originally propagated with.

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
