Set up a container underneath the funnel. 7. Pour the saturated calcium hydroxide solution through the funnel and into the container beneath. All undissolved calcium hydroxide has now been removed. At this point it is essential to calculate the molarity of the acid that will be used in the

Introduction The DAGMAR (Defining Advertising Goals for Measured Advertising Results) process‚ which was developed by Colley in 1961. This process has been very valuable towards advertising planning and setting objectives by placing an increased emphasis on different stages of the consumer decision-making process regarding final purchases. It uses the traditional hierarchy of effects model and suggests that the communication task must be specific and measurable. Therefore‚ it introduces a structure

The reaction mixture cooled 65% sulfuric acid was transferred to the 100mL round-bottomed flask through a glass funnel‚ three boiling stones were added to the mixture and the distillation started.

t-Pentyl Chloride is a compound that is created through an SN1 nucleophilic substitution reaction in addition with Hydrogen Chloride in order to isolate the product. A variety of procedural techniques were utilized during the experiment including extraction‚ washing liquids‚ drying liquids‚ gravity filtration‚ and simple distillation. When a single solute or compound is transferred between two different solutes‚ it is known as extraction. Another technique that was utilized was washing‚ in which

gently heated until the solution was boiling and then refluxed for 60 minutes. The solution was then transferred to a separatory funnel. 10 mL of DI water was added to the funnel. Then the funnel was carefully shaken and vented to allow gasses to escape. The solution was then allowed to rest for two minutes. After resting the bottom aqueous layer was drained rom the funnel. The water wash process was repeated again. Then the organic layer was washed with 5 mL of 5% sodium

thunderstorms and sweltering heat are the breeding grounds for a tornados’ formation. The first sign of a tornado is a strong dust whirlwind along with a funnel growing from the storm cloud. A more organized funnel descends farther from the cloud‚ sometimes even touching the ground. Funnel winds generally move counterclockwise and the funnel can move slowly or at about 100/ft per second. Eventually the tornado becomes fragmented and dissipates causing the end of the tornado. Tornados are the cause

is unlike food from anywhere else. As soon as you come in the gate‚ your mouth starts to water from the smells. They have chicken on sticks‚ funnel cakes‚ caramel apples‚ and much more. My favorite food at the fair is funnel cake. It smells so sweet and taste like heaven. With all the foods to choose from‚ I can never leave without eating a delicious funnel cake. The games are so much fun. I could play them for hours. When you walk around the fairgrounds‚ you can see all the games spread out.
