Explanation: Scientific method are the methods which help us to get acknowledged with thenew facts and theories which have been tested by the scientists through rigorous experimentation.
So the first step of scientific method is proposing a theory in which the scientists propose their facts and views under the name of the theory.
After proposing the hypothesis, testing of the hypothesis will take place by conducting an experiment. After the experiment has been conducted then only they can develop a theory and this will be their final step.
Thus the last step will be the 'developing a theory' .
Well the first step would be proposing a hypothesis, then you would test the hypothesis by conducting an experiment. So that means that the last step would be to develop a theory. Hope this helps!
Balanced equation: Pb(SO₄)₂ + 2 Zn → 2 ZnSO₄ + Pb From the equation we found that 2 moles of Zn form 2 moles of ZnSO₄ so 0.582 mole of Zn will produce 0.582 ZnSO₄ Molar mass of ZnSO₄ = 161.47 g/mole Mass of ZnSO₄ formed = 161.47 x 0.582 = 94.0 grams
