Answer:
true
Explanation:
one reason is because plants need sunlight and water because it is their source of food
Th actual yield of the reaction is 24.86 g
We'll begin by calculating the theoretical yield of the reaction.
2Na + Cl₂ → 2NaCl
Molar mass of Na = 23 g/mol
Mass of Na from the balanced equation = 2 × 23 = 46 g
Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol
Mass of NaCl from the balanced = 2 × 58.5 = 117 g
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
Therefore,
11.5 g of Na will react to produce = (11.5 × 117) / 46 = 29.25 g of NaCl.
Thus, the theoretical yield of NaCl is 29.25 g.
Finally, we shall determine the actual yield of NaCl.
- Theoretical yield = 29.25 g
Actual yield = Percent yield × Theoretical yield
Actual yield = 85% × 29.25
Actual yield = 0.85 × 29.25 g
Actual yield = 24.86 g

<h2>Example of Physical change </h2>
Ice forming and then melting back into water are an example of physical change because the nature of water is liquid. Yet when it freezes then it becomes into solid form. The water which is liquid then freezes to form ice form which is as a solid which is also a physical change.
If we see that when ice which is frozen and in solid form starts to melt by heat then it converts into water which is liquid form. This indicates that water freezes to form ice means liquid to solid therefore its shape changes which is a physical change. When ice melts it becomes solid to liquid it also changes shape and subsequently takes a physical change.
Answer:
Sandmeyer Reaction
Explanation:
When benzene diazonium chloride is treated with cuprous chloride in HCl, chlorobenzene is formed.
This reaction is called Sandmeyer reaction. In this reaction, the diazonium group is replaced by chloro group.
Sandmeyer reaction is used to replace the diazonium group with chlorine, bromine or cyano group.
