Goal of the planned mission MIRI is "to explore the Kupier Belt".

Explanation:

MIRI, Mid-infrared Instrument, was designed to play an important role in NASA's "James Webb Space Telescope"(JWST).This is a joint project involving the Space Agency Europe and Canada. This telescope is designed to bring the images of stars and galaxies in infrared light. This grasps a wavelength of 5 to 28 microns. It also has a sensitive dectector allowing to see the red shifted light, stars that are newly formed and the comet that are blur.

Also, to explore the Kuiper belt that is located in the outer solar system that extends from the Neptune to sun. It is believed to be similar to asteroid belt but 20 times broad and 200 times massive than it.

What is the total number of outer (valence) electrons in carbon dioxide, co2? answer?

Anuta_ua [19.1K]

Carbon dioxide has a total of 16 valence electrons.

1. To determine the number of valence electrons of carbon dioxide (CO2), first determine the number of valence electrons of each of the elements in the molecule.

a. We have 1 carbon (C) molecule, and 2 oxygen (O) molecules.

b. The carbon molecule has 4 valence electrons and each oxygen molecule has 6 oxygen molecules.

2. Add up the valence electrons of each of the elements

4 + (2 x 6) = 16
(from C) (2 oxygen molecules, with 6 valence electrons each)

Thus, CO2 has a total of 16 valence electrons.

The number of valence electrons can be more clearly seen from the Lewis structure of the CO2 in the figure below (Source: http://chemistry.tutorvista.com/inorganic-chemistry/bonding-electrons.html). The the dots surrounding the letters represent the valence electrons.
