Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>

Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3

The pressure exerted by an object given the force of the object and the area can be found by using the formula
where
P is the pressure
f is the force
a is the area
From the question
f = 2400 N
a = 0.4 m²
So we have
We have the final answer as
<h3>6000 N/m² or 6000 Pa</h3>
Hope this helps you
