Answer:
whole milk ,table salt , maple syrup
Answer:
See the answer below
Explanation:
Conservation is also a topic in Biology and it refers to the practice of managing natural resources - both living and non-living - with the aim of preserving them to secure the future of the human population.
Conservation in Chemistry refers to the property of chemical reactions in which no new matter or energy is created nor destroyed during the course of the reactions, although they can be converted from one form to another.
<em>Conservation in Biology and Chemistry can be likened to each other based on the fact that both deal with preservation. While conservation in Biology focuses on how the ecosystem can be preserved, conservation in Chemistry deals with the preservation of matter/energy. </em>
El agua con hielo es sistema heterogénea .
Answer:
C. Average Speed = 4 m/s
Explanation:
Average speed is defined as total distance travelled per unit time taken
From = 5s to = 10 s
Total time = 10 -5 = 5s
Distance travelled in first 5s= = 10 m
Distance travelled in first 10s = 30 m
Total distance between 5 s- 10 s = 30 - 10 = 20 m

empirical formula is the simplest ratio of whole numbers of components making up a compound
molecular formula is the actual number of components making up the compound
there can be many compounds having the same empirical formula
given options
1. C₂H₆ and C₄H₁₂
ratio of C to H in C₂H₆ - 2:6 --> 1:3
C₄H₁₂ - 4:12 --> 1:3
the simplified ratios for both are same
therefore both have same empirical formulas
2. C₃H₆O₃ and C₂H₄O₂
ratio of C to H to O in C₃H₆O₃ - 3:6:3 --> 1:2:1
C₂H₄O₂ - 2:4:2 --> 1:2:1
both have same empirical formulas
3. C₃H₈O and CH₂O
ratio of C to H to O in C₃H₈O - 3:8:1
CH₂O - 1:2:1
the 2 ratios of atoms are different which means they have different empirical formulas
4. C₂H₈ and CH₄
ratio of C to H in C₂H₈ - 2:8 --> 1:4
CH₄ -- 1:4
2 ratios are same so same empirical formula
correct answer is 3. C₃H₈O and CH₂O they do not share the same empirical formula
