Horatio used the flat end of a hammer to remove a nail from a piece of wood. This is an example of using a hammer as a(n) lever. pulley. inclined plane. wheel and axle.

Answer:

a. chromium (III) chloride

Explanation:

Chromium chloride is also binary ionic compound composed of only two element chromium and chlorine.

When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.

The anion name is end with suffix " ide".

such as chromium chloride.

The (III) shows the oxidation number of metal. In given compound the oxidation state of chromium is +3 while chlorine chow the oxidation state of -1 that's why three chlorine atoms are attached with one chromium atom.

Four commonplace items that depend on gas behavior to function effectively. Legs, arms, hands, and feet. window, chair, table, and shoes. air brakes, air compressors, air tires, and aerosol cans.

What is gas ?

One of the four basic states of matter, along with solid, liquid, and plasma, is gas. Individual atoms, elemental molecules derived from a single type of atom, or complex molecules derived from a number of atoms can all be found in a pure gas. A variety of pure gases can be found in a gas mixture like air.

If temperature and pressure remain constant, doubling the moles of a gas results in a doubling of its volume. An inflated tire takes up more room than a flat tire. Lungs enlarge as air is absorbed into them. Lung volume reduces when you exhale.

You will investigate four parameters that quantify gases in this activity: pressure (P), volume (V), temperature (T), and moles (n) of gas.

Thus, Four commonplace items that depend on gas behavior to function effectively.
