Answer:
The Following are the matching to this question:
Explanation:
- It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.
- Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.
- Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.
- The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.
- The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
- It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.
Answer:
Potassium chloride > Butanol >Propane > Ethane
Explanation:
Water is a polar solvent and it is likely to dissolve polar molecules.
KCl is ionic in nature and is completely polar and the solubility of the salt, potassium chloride is the highest.
Butanol can form hydrogen bonding with the water despite having a carbon chain. Thus, butanol will be at second.
Taking about, ethane and propane, both are non polar and least likely to dissolve in water. But, the extent of the London forces increases with the increase in the molecular weight. So, propane will dissolve faster than ethane.
The order is:
Potassium chloride > Butanol >Propane > Ethane
Answer:
It comes from the chemical reaction of The wax and the gas because the wax is made up of carbon-based chemicals so the gas and carbon make the candle light =)
Explanation:
Answer:
3 element i.e carbon (C), hydrogen (H) and oxygen.
Explanation:
The following data were obtained from the question:
Subtance >>>>>>>> Chemical Formula
Glucose >>>>>>>>> C₆H₁₂O₆
Methane >>>>>>>> CH₄
Ethanol >>>>>>>>> C₂H₅OH
Hydrogen peroxide >> H₂O₂
From the above table, we can see that ethanol (C₂H₅OH) contains carbon (C), hydrogen (H) and oxygen
Therefore, the total number of elements present in ethanol, C₂H₅OH is 3.
