Answer:
The answer is "Verification of results
".
Explanation:
The scientific system consisted inside an iterative or cyclical process which experimental results and technically confirm a theory. There are four things which scientific design aims people explain:
- Subject of investigation characterization.
- Hypothesis from its consequences of its characterization.
- Forecasts.
- Experimentation which show the precision and consistency of the hypothesis.
Its first stage of analysis involves collecting the samples taken for the current context, that are the focus of discussion, and then testing the samples taken to determine the absorbance of soft and hard salts throughout the water. It is required for water quality to be determined. Therefore, the collection and testing of samples falls under the scientific design category of classification, whereby Shamekha tried to verify the findings.
Answer:
12.0 g/mL
Explanation:
From the question given above, the following data were obtained:
Mass of Rock = 360 g
Volume of water = 150 mL
Volume of water + Rock = 180 mL
Density of Rock =?
Next, we shall determine the volume of the rock. This can be obtained as follow:
Volume of water = 150 mL
Volume of water + Rock = 180 mL
Volume of Rock =?
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 180 – 150
Volume of Rock = 30 mL
Finally, we shall determine the density of the rock as illustrated below:
Mass of Rock = 360 g
Volume of Rock = 30 mL
Density of Rock =?
Density = mass /volume
Density of Rock = 360 / 30
Density of Rock = 12.0 g/mL
Thus, the density of the rock is 12.0 g/mL
there is not enough information to make a prediction as we dont know what side she taped on magnet C
Answer:
H20
water (the chemical symbol, as used in non-specific contacts. 8 equals hydrogen equals oxygen and two elements in hydrogen therefore is known as H2O .
H202
hydrogen peroxide equals hydrogen peroxide is the chemical compound with formula h202. And it's your form, it is very pale blue liquid, slightly more vicious than water. It is used as an oxidizer, bleaching agent, and antiseptic .
Co=
carbon monoxide, carbon monoxide is colorless, odorless, and tasteless flammable gas that is slightly less dense than air. Formula equals Co
