Answer: B) metals, non-metals, metalloids

An example of a metal is iron. A non-metal example is oxygen, which is a gas at STP (standard temperature and pressure).

A metalloid is a bit of a mix between a metal and non-metal element. It's sorta like an element that has both properties of metals and non-metals, or it's in a murky gray area. An example of a metalloid would be silicon.

zavuch27 [327]
Safety glasses should be worn any time you are doing an experiment, especially one that involves chemicals or chemical reactions. They prevent chemicals or other materials from getting on or in your eye, and can prevent anything from mild discomfort to permanent blindness.

Some pairs of safety glasses have magnifying glasses on them, similar to bifocals. They can be used to more carefully examine something in an experiment.

What is an extensive property that can be calculated?
padilas [110]

Answer: The property which depends on the quantity of the substance is called an extensive property. The free energy change for a reaction (Δ G) depends on the quantity of the substance and is therefore an extensive property. It shows the additive nature. The extensive property Δ G is easily calculated from the formula, ΔG = -nFE cell.

What is the wavelength of an electromagnetic wave that has a frequency of
Alik [6]

Answer:

B

Explanation:

To calculate questions like this, you need to make use of the equation below:

ν = c / λ

ν is the frequency, c is the speed of light, and λ is the wavelength

ν = c / λ

2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)

λ = 0.122 m = B
