A Wedge is made by placing two inclined planes back to back.
A Screw is made by wrapping an inclined plane around a cylinder.
<u>Explanation:</u>
- A wedge is an uncomplicated machine that consists of two sloping planes, providing it a thin end and thick end.
- A wedge is used to separate or split apart objects.
- Force is employed to the thick end of the wedge, and in turn, applies force to the object along both of its sloping sides.
- A screw is a simplistic machine that consists of an inclined plane wrapped around a cylinder or cone.
- The absolute mechanical benefit of wedges and screws is invariably higher than 1.

Answer:
0.0526mol
Explanation:
The chemical equation given in this equation is as follows:
Na3PO4 + Sr(NO3)2 → Sr3(PO4)2 + NaNO3
However, this equation is unbalanced as the number of atoms of each element on each side does not correlate. The balanced equation is as follows:
2Na3PO4 + 3Sr(NO3)2 → Sr3(PO4)2 + 6NaNO3
This balanced equation means that:
2 moles of Sodium Phosphate (Na3PO4) is required to react with 3 moles of Strontium Nitrate (Sr(NO3)2)
Hence, if 0.0789 moles of Strontium Nitrate are reacted, then 0.0789 × 2/3
moles of sodium phosphate will also react.
= 0.0789 × 2/3
= 0.1578/3
= 0.0526mol
