2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
