<span>Science involves Observation. With out observation then you do not have science. So, if you were studying plants for instance, you would be looking at the plants and drawing conclusions based upon your observations and experiments (and the observation of the experiments). Something that is not scientific is the theories of how this world came about. Neither the evolutionist view or the Creationist view is scientific, no one can observe what happened thousands of years ago. The theories of how this world came about are merely faith based. Atheist put their faith in billions of years and Christians to a higher power. So that would be an example of something that is not scientific.</span>
Answer:
0.43 g/ml
Explanation: Density is d = M/V, where d is density, M is mass, and V is volume: therefore d= 32 g/75ml = 0.4266 = 0.43 g/ml
Answer:
Empirical formula is C₃H₄O
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
.
Given data:
Percentage of hydrogen = 7.14%
Percentage of carbon = 64.3%
Percentage of oxygen = 28.6%
Empirical formula = ?
Solution:
Number of gram atoms of H = 7.14 / 1.01 = 7.1
Number of gram atoms of O = 28.6 / 16 = 1.8
Number of gram atoms of C = 64.3 / 12 = 5.4
Atomic ratio:
C : H : O
5.4/1.8 : 7.1/1.8 : 1.8/1.8
3 : 4 : 1
C : H : O = 3 : 4 : 1
Empirical formula is C₃H₄O.
