You have been given an orange liquid and told to describe its properties. What methods would you use to observe, measure, and describe the physical properties of this orange liquid without changing it?

Removing the tree would decrease the water consumption but would also decrease the oxygen production.

What is a tropical rainforest?

Tropical rainforests are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.

Sunlight strikes the tropics almost straight on, producing intense solar energy that keeps temperatures high, between 21° and 30°C (70° and 85°F).

Deforestation has an adverse affect on air by reducing the amount of oxygen and increasing the amount of carbon dioxide as well as contributing to global warming.

Photosynthesis would produce food for the tree and as by - product, oxygen is produced.

Removing the tree would decrease the water consumption but would also decrease the oxygen production.

Answer:

The answer is radio waves

Explanation:

Answer:

Column 1. They have one valence electron

Column 2. They have 2 valence electrons

Transition metal column. Variable oxidation states

Column 3–7. Valence electron ranges from 3 to 7 electrons

Column 8. Completely filled i.e no valence electron

Explanation:

Final answer:

Each column of the periodic table represents elements with a specific number of valence electrons. Columns 1 and 2 have one and two valence electrons respectively, and are known for their reactivity. Transition metals typically have one or two, Columns 3-7 have 3 to 7, and Noble Gases in Column 8 have a full shell of eight, making them unreactive.

Explanation:

We can categorize columns, or groups, of the periodic table by the number of valence electrons, which are the outermost electrons in an atom that participate in chemical bonding.

• Column 1: These elements, also known as alkali metals, have a single valence electron in their outermost shell. These elements are highly reactive due to their tendency to lose this electron and achieve a stable configuration.
• Column 2: These are the alkaline earth metals, which have two valence electrons. They are less reactive than alkali metals but will still readily lose their valence electrons to achieve stability.
• Transition Metal Columns: These contain transition metals which typically have one or two valence electrons, although this can be more complex due to the filling of inner d orbitals.
• Columns 3–7: Elements in these groups have 3 to 7 valence electrons respectively. Many form covalent bonds by sharing their valence electrons with other atoms.
• Column 8: Known as the Noble Gases, these elements possess a stable full set of 8 valence electrons (except for Helium which has 2). They are very unreactive due to their stable electronic configuration.

Yes. I was able to think of non-living things suck as, a table and a chair and a countertop.
