How to distinguish between metals and non-metals
fiasKO [112]

Explanation:

Metals tend to have 1-3 valence electrons in their outer shell, while non metals have 4-8 electrons in their outer shell. Metals are natural elements that are hard, opaque, shiny and dense. While non metals are chemical substances that are soft, transparent, non-shiny and brittle. You can also distinguish a metal from a non-metal based on its appearance: metals are Lustrous while non metals are Non-lustrous. In other words metals are shiny while non metals are usually dull or simply "not shiny". Melting and Boiling point can also help distinguish between metals and non metals: metals tend to have : very high melting and boiling point. Nonmetals have Low melting and boiling point. Metals are also good conductors of heat and electricity, while nonmetals are poor conductor of heat and electricity. And lastly, metals are malleable and are always hard except for sodium, and nonmetals are non-malleable and are soft except for diamonds.

Which of the following is necessary to do a complete stoichiometric calculation?
jeka57 [31]

Answer:

Write the mole ratio.

Explanation:

The term stoichiometry is coined from two words: stoicheon(atom) and metron(measurement).

Stoichiometry uses the composition or chemical reactions of matter and the moles to quantity the elementary particles of a matter.

In order to do this, we use the mole ratio as the basis of the calculation. The mole is related to different parameters that we can obtained experimentally and theoretically about a reaction.
