Answer molecule
Explanation: The combination of two or more atoms, from the same or different elements, creates a molecule. Compounds are a type of molecules made of atoms from different elements held together by chemical bonds.
Answer:
1.07×10²¹ molecules are needed to sound the alarm
Explanation:
Let's convert the mass of CO to moles, to determine the amount of molecules.
0.05 g . 1 mol / 28 g = 1.78×10⁻³ moles
Now we can determine the number of molecules with the NA
1 mol has 6.02×10²³ molecules
1.78×10⁻³ moles may have (1.78×10⁻³ . 6.02×10²³) / 1 = 1.07×10²¹ molecules
The answer is all of them. But in a school situation, A would be appropriate. This is because the smoke gets into the smokers lungs, whether it be marijuana or tobacco, and can cause cancer cells to grow in your lungs and enter your bloodstream.
So A is the answer.
Answer:
Kayla sees afterimages of opposing colors when she stares at a poster for a long time.
Explanation:
The "opponent-process theory" is a theory developed by <em>Edward Hering. </em>It states that<u> three color pairs</u>, which are opposing in nature, are linked by the cone receptors. These pairs are:
- blue/yellow
- red/green
- black/white
This can be done when you stare at an<em> afterimage patch</em> for<u> 30 seconds.</u> Such as what Kayla is doing. Once the color stimuli is removed and she fixates her attention to a dot at the center of her field,<em> she'll notice the colors being reversed</em>. This means that if she sees the original color as<em> "blue,"</em> she'll see it now as <em>"yellow"</em> and<em> vice-versa</em>.
Extended inspection of a color in a pair results to it being <u>fatigued</u>. This allows the<u> non-fatigued color pair to be noticed</u>.
So, this explains the answer.
