132 cm to 0.00132 km.
there you go, hope this helps!
Answer:
Answer
The limitations are-
1. Privacy of the individuals involved in the research process.
2. Physical and psychological risks should be minimized
3. The subjects should be chosen equitably
4. Only reasonable exposure to risks is admissible.
Explanation
The privacy of the individuals involved in the research must be taken into consideration. This will ensure safety of patient data and information. The risk of physical and physiological well being of the person must be taken into consideration in such a research. In addition to that, the subject must be made to understand every procedure and the risks involved before testing. Moreover, only minimal exposure to risks is allowed and must have been previously tested in animals to avoid deaths.
<span>It exhibits the Tyndall effect. ---> FALSE. IT BELONGS TO THE COLLOIDES.
Brownian motion is not visible in it.--> FALSE. IT IS A PROPERTY OF FLUIDS WHEN MICROSCOPICAL PARTICLES ARE IN IT.
It cannot be separated using filtration.--->TRUE. THE PARTICLES CANNOT BE DISTINGUISHED NOR SEPARATED BY FILTRATION.
It has at least two phases.-->FALSE. E.G. SALT IN WATER FORM ONE UNIQUE PHASE.</span>
Answer:
Salt is the pure substance out of them all.
Answer:
Paraffin > Heptadecane > Hexane > 2,2-dimethylbutane > Propane
Explanation:
It must first be establish that all the molecules listed in the question are alkanes. For alkanes, the intermolecular forces between the molecules of alkanes increases with increasing molecular weight. This is as a result of increase in the surface area of the molecule. Increase in surface area implies a greater degree of dispersion forces.
This is the reason why high boiling points are observed for high molecular weight alkanes.
