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.
The remaining 3 % are nanomaterials made from e.g. aluminium oxide, barium titanate, titanium dioxide, cerium oxide and zinc oxide. Carbon nanotubes, graphene and fullerenes have annual production amounts in the hundred tonnes range. Nanosilver is estimated to be produced in about 20 tonnes per year.

Answer:
Cl
Explanation:
Electronegativity increases as you move up and to the right of the periodic table. For example, Florine is the most electronegative element.
1. %yield = actual yield / theoretical yield x 100
= 3 g / 4. 46 g x 100
= 62.11 % percent yield
