Nonmetal, for example, the Noble Gases, or Hydrogen.

It is 100% Nonmetal, why? Because gas is not metallic (so that crosses out metals and metalloids), and can't conduct, in any way.

An irregular chunk of iron has a density of 7.87 g/cm3. A 14.5 gram chunk is added to a graduated cylinder. If the final volume

bulgar [2K]

Answer:

37.96 mL

Explanation:

From the question given above, the following data were obtained:

Density (D) of iron = 7.87 g/cm³

Mass (m) of iron = 14.5 g

Volume of Cylinder + Iron = 39.8 mL

Volume of Cylinder =?

Next, we shall determine the volume of the chunk of iron. This can be obtained as follow:

Density (D) of iron = 7.87 g/cm³

Mass (m) of iron = 14.5 g

Volume (V) of iron =?

D = m/V

7.87 = 14.5 /V

Cross multiply

7.87 × V = 14.5

Divide both side by 7.87

V = 14.5 / 7.87

V = 1.84 cm³

Recall:

1 cm³ = 1 mL

Therefore,

1.84 cm³ = 1.84 mL

Therefore, the volume of the chunk of iron is 1.84 mL.

Finally, we shall determine the starting volume of the cylinder as follow:

Volume of Cylinder + Iron = 39.8 mL

Volume of Iron = 1.84 mL.

Volume of Cylinder =?

Volume of Cylinder = (Volume of Cylinder + Iron) – Volume of Iron

Volume of Cylinder = 39.8 – 1.84

Volume of Cylinder = 37.96 mL

Therefore the starting volume of cylinder is 37.96 mL

Whats the periodic table in order?

Liula [17]

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

hope this helps!

What is the frequency of green light, which has a wavelength of 4.90 x 10

Lina20 [59]

Answer:

I found:

ν=6×10^14Hz

Explanation:

You can consider that wavelength λ and frequency ν are related through the speed of light in vacuum c as:

c = λ ⋅ ν

so:

3 * 10⁸ = 4.9 * 10-⁷ * V

v =3 *10⁸/ 4.9 *10⁻⁷ = 6 * 10¹⁴HZ
