If I could change something in my previous science classes, it would have been the fact that I struggled in the question concerning exponents. It was simple one, but I don't know how I didn't understood that. For example, if there is a question with a calculation "xy²", then I would first multiply x and y, and then calculate the exponent. I did 3 of the questions wrong because of this, it was when I was in 7th grade. I wish I had not done this kind of silly mistake. I an in 10th grade and understand it well now, though.
The model has resulted into a formula called the Rydberg formula. It also came about from the electron transfer within the hydrogen atom. The formula is shown in the picture, where RH is the Rydberg constant and λ is the wavelength . Thus, the solution is as follows:
1/λ = (1.0973731×10⁷ m⁻¹)(1/2² - 1/3²)
Solving for λ,
<em>λ = 6.56×10⁻⁷ m</em>
Answer:
Insoluble
Explanation:
Like other non-polar molecules such as petrol, wax and grease, most food and dirt is not soluble in water.
