Objective: One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner

The Balmer series is characterized by the electron transitioning from n ¡Ý 3 to n = 2‚ where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-¦Á‚ 4 to 2 is H-¦Â‚ 5 to 2 is H-¦Ã‚ and 6 to 2 is H-¦Ä. As the spectral lines associated with this series are located in the visible part of the electromagnetic spectrum‚ these lines are historically referred to as H-alpha‚ H-beta‚ H-gamma and

Fibonacci sequence in arithmetic sequence The Fibonacci sequence is a series of numbers in which each number is the sum of the previous two. It starts with 0 and 1‚ which equals 1. Then 1 plus 2 equals 3‚ 2 plus 3 equals 5‚ and so on. n mathematical terms‚ the sequence Fn of Fibonacci numbers is defined by the recurrence relation With seed values[1] The Fibonacci numbers are represented practically everywhere. In the petals on a flower‚ or the arrangement of leaves along a stem‚ you

Purpose: We are doing this experiment to find the best ratio of potassium nitrate to powdered sugar for a model rocket motor that will create the most thrust. We are also testing if adding fins will affect the flight distance of the rocket. Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson‚ who has experimented with the best ratio of powdered sugar to potassium nitrate‚ has stated that “The 1 to 3 ratio is best for creating the most amount of thrust

Solution: Apply integral test: Z Z ln R 1 X R 2 1 p dx x (ln x) p=1 p 6= 1 let ln (x) = u then ln 2 so that when p = 1 and p < 1 integral diverges by letting R ! 1‚ so does the series. When p > 1 then integral converges to ! 1 p 1 p 1 p (ln R) (ln 2) (ln 2) lim = ‚ R!1 1 p 1 p 1 p so does the series. 2. (18 pts.)

tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds (81 degrees)‚ preformed the experiment for two more
