Answer:

Energy: Radio Waves least, Infrared 2nd,, Blue light 3rd, Gamma Rays 4th

Wavelength: Gamma Rays smallest wavelength, Blue light 2nd, Infrared 3rd, Radio waves 4th

Frequency: Radio Waves smallest frequency, Infrared 2nd, Blue Light 3rd, Gamma Rays 4th

Explanation:

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

There are two different compounds of sulfur and fluorine.

weqwewe [10]

Atomic mass of F: 19.0 g/mol

Atomic mass of S: 32.1 g/mol

1.18 g F = [1.18 g / 19.0 g / mol] = 0.062 mol F

1 g S = 1 g/ 32.1 g/mol = 0.031 mol S

Divide by 0.031

0.062 mol F / 0.031 = 2 mol F

0.031 mol S / 0.031 = 1 mol S

SF2 Then X = 2

Verification:
F2 = 2*19.0 g = 38 g F
S = 32.1 g

36 gF / 32.1 g S = 1.18 g F / g S

A helium-filled weather balloon has a volume of 512 L at 18.9°C and 756 mmHg. It is released and rises to an altitude of 2.14 km

vazorg [7]

633.97 L

Explanation:

Well use the combined gas law;

P₁V₁T₁ = P₂V₂T₂

We need to change the temperatures into Kelvin;

18.9°C= 292.05 K

5.9°C = 279.05 K

756 * 512 * 292.05 = 639 * V₂ * 279.05

113,044,377.6 = 178,312.95 V₂

V₂ = 113,044,377.6 / 178,312.95

V₂ = 633.97 L
