- ..1.. 4.. . I6 Il 7 Scenario 2 The airbags in vehicles contain a mixture of NaN,, KNO, and SiO, When a car decelerates at a rapid pace, an electrical signal goes to the gas generator inside the airbag, triggering a series of three chemical reactions: 10NAN. 10NA +2KNỎ, K,O + Na,0 + Na + SiO, - K,SiO, 10NA + 15N,(g) KO + 5Na O + N,(g) These reactions produce gas (N.) to fill the airbag and convert sodium azide (NaN,), a highly toxic substance, to alkaline silicate (K,SiO ). The quantity of NaN, must be carefully calculated to ensure that the volume of gas is adequate to fill the airbag firmly enough to protect the passenger but not overfill and cause the bag to explode. A standard airbag needs 67 L of N, (g) to properly inflate. notes23 24 25 26 27 28 A chemist prepares a solution of mercury(II) lodide (HgI,) by measuring out 0.00033 umol of mercury(II) iodide into a 150. mL volumetric flask and filling the flask to the mark with water.

- (A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Tap water is more pure than distilled water. The purity and cleanliness of distilled water remains constant no matter where you get it from, because of the process it has undergone. 2. Carbon dating is an application of nuclear chemistry where they use the amount of C-14 in a fossil to determine its age. Nuclear power plants produce radioactive wastes. 3. The density of water is dependent on its temperature. A water molecule has a linear structure because of the neutral charges of its atoms. 4. Sedimentation is a chemical water treatment process using gravity to remove suspended solids from water. Colloids are not likely to settle naturally because of Brownian motion and electrostatic forces balancing the gravity. 5. Uranium is mined. A uranium ore may directly be used as a fuel in a nuclear…for number 10, do we have to match the color of the solution, like if it was red we make it read or should we match it with the color absorbed by the solution, such as green- red, orange- blue, and so on?Timely matter!
