It would be: 2*3 = 6 oxygen atoms
OPTION D IS YOUR ANSWER......
We know the volume of one mole of gas at 273 K and 760 Torr is 22.4 L. Using
(PV)/T = constant
We can calculate the volume of the gasses at the given conditions:
(P₁V₁)/T₁ = (P₂V₂)/T₂
(760 * 22.4) / 273 = (288 V₂) / 308.2
V₂ = 66.7 L
Mass of He: 4
Mass of Ne: 20
Fraction of Ne: x
Fraction of He: 1 - x
avg density = (∑(component fraction × component mass))/volume
0.2460 = (20x + 4(1 - x))/ 66.7
x = 0.775
A(n) Business Unit is a dynamic sub-organization that can be created and eliminated depending on need.
<h3>What is Business Unit?</h3>
Business unit is when the company wants its sales in a segmented way. This market offer, or it can be, for example, business area, segment line, market performance cases.
This strategy consists of the form adopted by many companies that divide their activities into independent business units, with different results, strategies and managers.

-------------------------------------------------------------------------
2. The Milky Way galaxy is described as a disk of stars orbiting a central point on the disk. Which of these best explains why people on Earth cannot see the entire shape of the Milky Way?
A. Earth is a part of this galaxy.
-------------------------------------------------------------------------
3. A student learns that the sun is classified as a medium-size star and that many stars are much bigger and brighter. However, the student observes that other stars look very dim, even through a telescope.Why do other stars look much dimmer than the sun?
D. As light from other stars travels through space, it gets reflected.
-------------------------------------------------------------------------
4. The sun is a mid-sized, main sequence star. What stage is next in the life cycle of the sun?
A. red giant

5. In November 2013 an object orbiting the sun seemed to disappear behind the sun. When a satellite did not detect the object, astronomers thought that the object had been destroyed when it passed close to the sun. However, when another satellite detected a small, bright object with a fan-shaped tail, astronomers proposed that the object was not destroyed.What type of object were astronomers most likely observing?
A. A comet
Answer:
Answer: C
Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde.
Melamine formaldehyde is a thermosetting plastic (or thermoset) that strengthens as it is heated during its preparation.
