The first step in the scientific method is Observation, where scientists describe phenomena in the natural world. Afterwards they ask a question, form a hypothesis, conduct an experiment, and arrive at a conclusion.
The first step in the scientific method process is typically Observation, where scientists notice and describe phenomena that occurs in the natural world. For example, a scientist may observe that a plant does not grow taller in the absence of light. Other steps that follow include forming a question, forming a hypothesis, conducting an experiment, and drawing a conclusionbased on the results of the an experiment.

Answer:
1) 6(1/2)
2) 8(4/5)
Explanation:
1) 7 - 1/2 = 7/1 - 1/2 = 14/2 - 1/2 = 13/2 = 6(1/2)
2) 11(2/5) - 2(3/5) = 57/5 - 13/5 = 44/5 = 8(4/5)
Answer:
13.39 mol ≅ 13.4 mol.
Explanation:
Using cross multiplication:
1.0 mole of Cl₂ occupies → 22.4 L.
??? mole of Cl₂ occupies → 300.0 L.
∴ The no. of moles of Cl₂ are in 300 liters = (1.0 mol)(300.0 L)/(22.4 L) = 13.39 mol ≅ 13.4 mol.
Answer: Distillation
Explanation:
Distillation is the process of purifying a liquid by successive evaporation and condensation. Water vaporises at a lower temperature compared to the ink pigment, therefore, the mixture is heated to boiling so that the water evaporates leaving the ink pigments in the flask. The evaporated water can the be passed into a condenser which converts the water vapour into liquid.
Answer: Distillation
Explanation: Separate ink from water using a process called distillation. This is a process of separating two substances mixed together. Water vaporizes at a lower temperature than the ink pigment so if you heat them, the water evaporates, leaving the ink pigment in the flask.
The density would be the same for the whole bar as well as one half of the bar. Density is a identity I believe, by this I mean that it stays the same no matter how little or how much of the same substance you have. Since density = mass / volume, half the bar has half of the weight as well as half of the volume of the whole bar, making the density the same.
For example, a block weighs 10 grams and has a volume of 5 ml. the density would be d = 10/5 or, d = 2g/ml
Half of the block weighs 5 grams and has a volume of 2.5 ml. The density is d = 5/2.5, or, d = 2 g/ml.
See, although there are different amounts of the same substance, their density is the same.
