Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>

Answer:
0.87mole
Explanation:
The reaction equation is given as;
4Fe + 3O₂ → 2Fe₂O₃
Number of moles of Fe₂O₃ in 138.5g
To solve this problem;
Number of moles =
Molar mass of Fe₂O₃ = 2(56) + 3(16) = 160g/mol
Now;
Number of moles = = 0.87mole
