Answer 2

I have searched the web for your query and found some relevant results. Here is a summary of what I found:

- The query is about a laboratory experiment on identifying simple and complex substances by their names and formulas. The experiment is part of the chemistry curriculum for the 7th grade in Ukraine . - The experiment involves observing samples of different substances in test tubes, such as water, sulfur, phosphorus, magnesium, sodium hydroxide, carbon, iron oxide, iron, zinc oxide, calcium carbonate, aluminum, zinc, calcium oxide, and sodium carbonate . - The task is to classify these substances into two groups: simple and complex. Simple substances are further classified into metals and non-metals. The classification is based on the number of atoms in the formula of the substance and their physical properties, such as metallic luster, malleability, electrical and thermal conductivity, color, etc . - The answer is given in a table, where the name of each substance and its type are indicated by putting a "+" sign in the corresponding column. For example, sugar (C12H22O11) is a complex and organic substance, while copper (Cu) is a simple and metal substance.

I hope this helps you with your experiment. If you need more information, you can follow the links to the web sources below. Have a nice day!
