Water has highest surface tension
Answer: Option (c) is correct
<u>Explanation:</u>
There are molecules present in every liquid. Attachment of these molecules with each other gives rise to surface tension. It is the result of intermolecular forces. It is due to surface tension the insects float on a liquid.
The water has the highest surface tension. it is because molecules present on the surface of the water are held together by very strong hydrogen bonds. There is high attraction among the molecules of water.
The statement that best describes the effect of low ionization energies and low electronegativities on metallic bonding is the first one - the valence electrons are easily delocalized.
Due to these low energies and negativities, valence electrons can be moved around quite easily and their positions may be altered quite drastically.
Answer:
Copper(II) sulphate – sodium hydroxide reaction
The reaction between copper(Il) sulphate and sodium hydroxide solutions is a good place to start. If you slowly add one to the other while stirring, you will get a precipitate of copper(II) hydroxide, Cu(OH)2.
Carbon dioxide (CO2)
Argon (Ar)
Hydrogen (H)
Helium (He)
<span>Based on the experience of the responder, to correctly calculate measurements in real-world. Firstly is to avoid errors as much as possible. Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.</span>
