Amedium-temperature star like the sun would most likely emit its most intense radiation as a. ultraviolet light b. visible light c. microwaves d. radio waves

The correct answer is option B, that is, visible light.

Explanation:

The Sun is a prime source of ultraviolet rays. Although the Sun discharges all of the distinct types of electromagnetic radiation, 99 percent of its rays are in the form of ultraviolet rays, visible light, and infrared rays. The Sun emits radiation all through the electromagnetic spectrum, that is, from extremely high-energy X-rays to ultra-lengthy wavelength radio waves, and everything that comes in between. However, the peak of the emission takes place in the visible part of the spectrum.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.
