Answer:
Measure the pH of different household chemicals
Explanation:
To demonstrate a chemical property using an experiment, measuring the pH of different household chemicals will be the best way. The pH is the degree of hydrogen or hydroxyl ion concentration in a solution.
Chemical properties tell us about what a substance can do.
It shows if a substance will react with other substances or not.
Examples are flammability, rusting of iron, precipitation, decomposition of water by electric current e.t.c.
Measuring the pH is a chemical property determination procedure.
The pH points to the degree of acidity or alkalinity of a solution.
Answer:
See attached picture.
Explanation:
Hello.
In this case, since butane has two common occurring structures, n-butane and isobutane, there is a way in which the tert-butyl radical can be formed upon the removal of a hydrogen from the isobutane form of butane as shown on the attached picture, wherein you can see that the radical is named by "tert" since the central carbon is bonded to three carbon atoms, that is why we classify it as tertiary. Moreover, it is a radical due to the presence of the bolded dot next to the tertiary carbon suggesting that it is very likely to bond with an other atom.
Best regards.
The PH of 10% HCL solution is 11
A cell is made of molecules and a molecule is made of atoms. That's the simplest way of putting it. More complicated is that a cell is made up of macromolecules, such as proteins, lipids, etc. A molecule is a particular configuration of atoms.
