8.43
58.44g/mol*1/6.93g= 8.43moles of NaCL
Answer:
No additional information is required in order to calculate the molality of the solution.
Explanation:
Mole fraction of water = 
Mole fraction of sucrose = 
From the given mole fraction of water mole fraction of sucrose can be determined.
And from both values of mole fraction moles of water and sucrose can also be calculated.
After calculating the moles of water convert them into mass of water in grams and then change that into kilograms say that be M'.
Finally we can determine the molality of solution ;
Molality of the sucrose solution ;
From this we can conclude that no additional information is required in order to calculate the molality of the solution.
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.
True
the definition of matter is any substance that has mass and takes up space.
