A reaction between two pure solids is very rare. For a reaction to occur, the molecules must interact with each other. Since molecules of solids are very compact, they don't have the liberty to collide with one another. However, this is made possible by hydrates of solids. An examples would be CuSO₄·5H₂O. In this case, they have a an intermediate liquid to react them together.

A resistor of 5 Ω is placed in a circuit. The voltage drop across the resistor is 12 V. What is the current through the resistor
Kaylis [27]
<span>Data:

</span>R = 5 Ω
U = 12 V
i = ?
<span>
Formula:

</span>U = R*i → i =  \frac{U}{R}<span>

Solving:

</span>i = \frac{U}{R}
i = \frac{12}{5}
\boxed{i = 2.4A}

Answer:

<span>The current through the resistor is 2.4 Amperes</span><span>
