1.) the diagonal of a rectangle is 25 meters long and makes an angle of 36 degree with one side of the rectangle. Find the area and the perimeter of the rectangle. 2.) A side of a square is 16 inches. The midpoints of its sides are joined to form an inscribed square. Another is drawn in such a way that its vertices would lie also at the midpoints of the sides of the second square. This process is continued infinitely. Find the sum of the areas of these infinite squares. 3.) A rectangle and a square have the same area. If the length of the side of the square is 6 units and the longest side of the rectangle is 5 more than the measure of the shorter side. Find the dimensions of the rectangle. 4.) Find the height of a parallelogram having sides 10 and 20 inches, and an included angle of 35 degree. Also, calculate the area of the figure. 5.) A certain city block is in the form of a parallelogram. Two of its sides measure 32 ft. and 41 ft. If the area of the land in the block is 656 square feet, what is the length of its longer diagonal? 6.) The area of an isosceles trapezoid in 246 square meter. If the height and the length of one of its congruent sides measure 6 meter and 10 meter respectively, find the two bases. 7.) An isosceles trapezoid has an area of 40 square meters and an altitude of 2 meters. Its two bases have ratio of 2 is to 3. What are the lengths of the bases and one diagonal of the trapezoid? 8.) A piece of wire of length 52 meters is cut into two parts. Each part is then bent to form a square. It is found that the combined area of thee two squares is 109 square meter. Find the sides of the two squares. 9.) A rhombus has diagonals of 32 and 20 inches. Find the angle opposite the longer diagonal. Also, determine its area. 10.) If you double the length of the side of a square, by how much do you increase the area of that square? 11.) If the diagonal length of a square is tripled, how much is the increase in the perimeter of that square? 12.) If...

Maggie Liu
Abstract
The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical...

...THE PURITY AND PURIFICATION OF SOLIDS
MELTING POINTS
ABSTRACT
Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities.
INTRODUCTION
The melting point of a...

...alloys still in use today became available.
The die casting process has evolved from the original low-pressure injection method to techniques including high-pressure casting — at forces exceeding 4500 pounds per square inch — squeeze casting and semi-solid die casting. These modern processes are capable of producing high integrity, near net-shape castings with excellent surface finishes.
The Future
Refinements continue in both the alloys used in die casting and the process...

Unknown Solid – 2
Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water, the solution turned pink which...

...The Purity and Purification of Solids
Recrystallization
ABSTRACT
In this experiment, impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the...
